8mm head on a bolt usually means M5 bolt, or maybe M6? Hadn't thought about cruise control...I guess I could work it into the system somehow? But would need the control diaphragms cable attached to the accelerator cable somehow
Well I just came in from a frustrating couple of hours
One of the relays I wired in when I first started the wiring was making a loud buzzing sound when energized (key ON position) Some research told me that usually means it's a bad ground. It would buzz with the power probe clipped onto the bolt holding the ring terminal to the body, but not with the ring terminal floating in mid air with the probe clipped to it...re did the ring crimp (and solder this time) cleaned the bolt, cleaned paint off the bodywork...still buzzing. Pulled the signal and earth terminals out of the relay socket, plug directly to relay, no buzzing
Anyway, after re-doing many crimps, earths, suspecting riv-nuts causing a bad earth connection, un-plugging the fuel pump fixed the buzzing
That relay was sending power to the pump, but the pump earth return wasn't earthed...or was it...? There was me thinking the 2 pin plugs on these things had one vertical pin for positive, horizontal for negative. Not on this fuel pump! Didn't help that I didn't know the pump bracket HAS to be isolated from the body. So I had a short circuit...
Note to self, put some rubber washers under that bloody fuel pump bracket
