When I removed the wiring loom from my bus I removed and labelled all the wires from the diagnostic socket. Now I’ve refitted everything but before I un-label all the wires I thought I’d post up the terminal numbers and colours as they maybe helpful to anyone doing the same. Terminal numbers and colours as follows: (1974 1600 bus) 5 blue with white stripe 6 grey 7 yellow with red stripe 8 brown with black stripe 10 black with white tracer 11 black with green stripe 12 black with red tracer 13 grey/be1ge with green stripe 14 black 17 brown with white stripe 21 & 22 yellow to sensor on bell housing. there’s also 2 large terminals in the centre- red/white (b+) and brown (earth).
I hadn't got the heart to take them to my flywheel sensor, so just neatly coiled up the cable instead
Yea I know it’s totally pointless- I don’t suppose it was a particularly accurate way of diagnosing anything even back in the day when it was considered cutting edge technology but since my socket and wiring/terminals were original and intact, I didn’t have the heart to take the snips to it…..

I did a complete rewire on mine so the decision was easy. Usb chargers and blade fuses were top of my list. I did put my diagram on here somewhere I think.
