Set the meter for beep test or resistance (lowest setting) connect the black wire on the meter to a good chassis earth and prod the wires with the red probe. If it beeps or shows a low reading then its probably an earth wire. No beep and it'll probably go live when its all reconnected and the relevant switch is operated.
ANYTHING not brown or black that beeps will need to be investigated.
If the car was running before you started investigating the faults then most of the loom is probably sound.
Have you got a haynes manual for it or a wiring diagram?
Cheers for this. will set it to the resistance/beep setting and give it all a good test. It is something i want to get better at and understand more.
I do have a haynes manual which i was checking stuff with. Only played attention to the cig lighter and it had a black and red wire going to it just hard to figure which way it would go round but i'm guessing the sold bullet connector wouldnt be for an Earth haha.
