Restorations and build ups. We will test this and see how it goes. A personal forum for members with major builds going on. This way we can keep all the posts together. If you have a major build going on let me know and I will set you up with your own area. If you have threads already running also let me know and I will then move them to your area. See the two I have added to get an idea of what I mean.

on the Mitsuba - gosh, that mariage was close wasn't it ? I recently saw MY wagons with intermittent wipers and the knob was a two tiered set up, unlike my Brumby sourced single tiered switch. Second tier just the rear wiper squirter ? Guess same can controller ? Wonder if your wire diagram reflects the two switches in MY and MV ?

Jonno, you're right there is a 2 tiered switch setup in the wagons, for the rear wiper + washer as well. There's 2 rotary can style switches bolted together inside the dash, with a shaft passing straight through the first one to the switch behind. Each switch has its own plug I think, rear wiper one having only 3 or 4 wires as opposed to front with 5.

Anywhoo...I love it when goodies arrive Takes my mind of being bored not at work and with a nasty cold

This lot cost a pretty penny I can assure you!


And with two of these bad boys I hope to never see a fusible link in my life again! Can be manually operated too to isolate that whole side of the wiring if need be, and that red tab pops out when it is tripped as a visual aid when you're looking around under the bonnet.


As we speak my wiring diagram is getting blown up and printed + laminated in A0 size, picking that up later today.

A wiring loom is born!



A few points worth mentioning:
- I VASTLY under-estimated the amount of wire I was going to need! And the number of different colors, and gauge. I've already doubled up on some colors and run out of others, can't do the wiring for the front fog lights as I don't have a gauge thick enough apart from the 6mm which is too thick Also going to need about every different color/stripe combination for all the relays, sensors and dash lights.
- Not sure if the peg board is really worth the effort. It's a bit fiddly as in you can't "hang" the wires up there, they're too stiff/springy and have a mind of their own, had to tape, zip tie and clip them all together and onto the rope. But for getting the length and position right it's pretty good, not having to thread each wire one by one through the firewall and engine bay.
- I need plain/un-insulated wire splices (picture brass tube) The heat shrink insulated ones are okay but you have to physically cut the wire and then re-join using the splice instead of stripping one wire in the middle of its length and just adding the other one. Having 2 wires in one side that don't want to fit in and one wire the other side which is almost too small for the heat shrink.


I'm thinking about finishing up the longest wires in the engine bay (fog lights) and just doing the rest in the car, being all the wires between the inside fuse box and light switches, relays etc. Since those will only be 30-50cm long at most there's not much point doing them on the board.

Also the other day I peeled the old loom of its tape and covering, salvaged what wires I could but interestingly none of them are very long before they meet a splice or connector, so not much usable came from it. And man, was this an eye-opening experience! The whole lot is so simple and almost pre-historic Glad I'm upgrading it.

What a day I'v got so much done in the last 2 days it feels like I'm making heaps of progress.

I did about all I could on the board (not as much as I thought as it turned out...was hardly worth putting all the effort into the peg board!) Tidied up the wires with strategically placed bands of electrical tape and grouped the breakout points and then transferred the whole lot into the car/engine bay. The loom-to-be measured up absolutely (I mean perfectly) with all the wires exactly the right length and the breakouts in exactly the right place. Created some bracketry to mount the Lib fuse box and went about crimping and installing all the new wires into the Lib plugs for a plug and play affair. Hardest bit was removing the old terminals from the plugs; a flattened and perfectly shaped nail was the only thing small enough to get in there to lift the locking tab. Then today was more crimping, heat shrinking, plugging in, mounted and wired up 3x relays near the battery for high beams, "ON" power (fuel pump, ignition coil, fuel cutoff solenoid) and "START" power (starter motor solenoid) I got relays with 2 x output pins on them sort of by accident but it turned out to be really useful for powering multiple items from 1 relay.

So now the Lib fuse box is installed and 90% wired up. Just need a couple extra wires for the thermo fan relays. I used my test power probe in combo with the multimeter to test all the relays and to see if all the (imaginary at the moment) accessories were getting power from the fuse box, 100% all working perfectly Tomorrow I have to mount 2 x 50A heavy duty relays up near the firewall that will throw power into the interior fuse box, then I can start wiring up the internal fuse box and internal accessories. The 50A relays have big copper spade terminals on them (must be 10mm?) would you believe the "10mm" crimp terminals I ordered aren't big enough! Must be 9.80mm and the buggers just don't go on. Maybe I'll try and get some relay holders for these. One other interesting thing; I went to re-use some wires from the original loom, cut the ends back a bit and stripped them...the copper strands were all dark green! Cut back some more; still green! Almost every wire I tried was pretty much green or patchy all the way through. Glad I'm replacing this!

Just thinking...I could almost make a plug and play kit for people to upgrade their MY's to Lib fuse box and relay power, being that I'm pretty well un-employed at the moment

Baby wiring loom in the engine bay

It's a bit of tangle near the fuse box at the moment, but here are the plugs all wired up. I'll sort this out better when it comes to wrapping the loom

Relays and fuse box installed; The dodgy looking bracket holding the fuse box to the strut tower will be replaced with something stronger and prettier, but it does the job for now.

Looking good!

I'm liking this revelation. i will defiantly employ your services for my Brumby

(quad headlight, sports dash, aircon )

Kewl - like it ...

What are you doing for ignition ? - upgrade to Electronic ?

I would also try & run the wires hidden as much as possible - like over top of radiator behind / inside fenders, etc. to help keep it clean & tidy ...

You should checkout the 'Drag Brumby' for inspiration : https://www.facebook.com/Drag-Brumby...3141/timeline/

Cheers, Bantum ...

Heh that drag Brumby is tidy all right, not a wire in sight! I didn't plan on hiding everything so it's probably too late now to run the loom through the fenders, since all the wires would be too short. Not too fussed about hiding them though, once it's all wrapped up it will look neat enough for me anyway.
As for ignition, I'm probably going to do an EDIS programmable setup (megajolt or some such) and do away with the original coil and dizzy...and not only because I put the new fuse box where the coil should be but I've always hated the original ignition systems points or electronic. They've always been a huge failing point and have left me stranded and frustrated more than once. I'm going all out on everything else with this car so why not ignition as well

Todays progress: More relays! 2 x 50A heavy duty ones up near the firewall for the interior fuse box. Making the bracket for them took alot longer than planned since my angle grinder has decided it doesn't want to be parted from its beloved wire brush...had to cut everything with hacksaw and hand file
Also got some relay sockets for the 3 by the battery, looks much neater now.

New heavy duty relays mounted and wired up

New sockets for the ones I did the other day

Plus my intermittent wipers They're wired up according to the plan I made but whether they work or not is yet to be seen. I still need to wire up the switch in the cabin and sort out an intermittent pulsing circuit. I'll order some relay sockets for these to neaten it up and put them all in a sealed box near the wiper motor/fuel pump.


Plus I wired up the ignition switch and used the test power probe and checked that all my relays were working correctly...couldn't help but make a little demo vid

Top effort mate!

I too was going to sugget hiding the wiring but if you're happy with it that's all that matters!

I still can't get over the paint job on that wagon!!

Cheers

I know right! And The more I look at the paint the more I want to see it driving around out in the sun Getting seriously antsy about it now, can't quite believe it's already been a year since it was painted! It's taking a ridiculously long time.

More progress today on the wiring; it feels like I'm flying through it and I'm testing every circuit as I go and so far everything has worked flawlessly. Seriously that test power probe is the single best $50 I've spent so far on this wiring overhaul. Followed by the wire stripper and ratcheting crimp tool with changeable jaws.

Last couple of days has been spent under the dash. I've bussed all the ACC, ON and BATT fuses together on the interior fuse box, now just adding the other side of each fuse one by one as I complete the circuits in the car. I've put a dedicated lead from the battery to the interior fuse box for the rear power sockets I have planned so no splices or cuts in it for reliability. I've also completed the headlights switch, high beam and indicator/hazard switch (plug with 10 wires in it!) complete with new LED flasher cans and front wiper/washer switch with intermittent function. I managed to rig everything up with the power probe to test my 4 relay wiper arrangement and it works perfectly, self parking feature and all It's great hearing all the little relays click on and off working together. Although I can't test the intermittent function until I wire in an intermittent timer circuit, I think Jaycar has a kit for this. As it is now directly wired the INT switch position is just the same as the low speed position.

Have to say this wiring job is coming together really well and I am actually enjoying it, not as daunting as I first thought and the end result is going to be so much better than original. Now I pretty much have to start doing the rear end of the car, for this the main lead back there will be 7 core trailer cable, with a few extra wires following it down for any extras.

All the plugs correctly wired and working. Everything is just mocked up at the moment to get wire lengths right, it will all come out again so I can clean the floor up and put sound deadening down.

Another thought - get a battery box! You don't want battery acid ruining your Purdy paint job!! Plus a battery box looks neat as when you've got the right box in there

I too love wiring, mine is not as neat as that as I've just added what I've needed, when needed and typically laid it over the top of everything else in there. The EJ conversion wiring is another thing though, there's only one thing I'd change in that if it ever comes out of the vehicle again

Cheers
