I am installing the wiring harness back into my build and have the following mysteries (to start with) - The car is a Sierra 1lt 1984.

Front end almost sorted except I have a Green wire near the starter motor/Carby area and 1 T plug with a Black/White trace and a Black/Blue trace wires in the centre of the firewall next to the T plug for the reverse light switch.

Rear of the car all sorted except a T plug with a Green and a Black/white trace wire.

I can not find any of these on the wiring diagram - Anyone know what they are?

Do they have power with ing on??

If not, earth em & see what light on the dash turn's on..

One could be for the 4wd light ( yes I know it may not have one)
The other could be your fuel sender.

I'd power it up , they may not be needed....

is it a 1 litre harness or a 1.3?

is the green wire part of the starter or carby harness or coming out the main one? might it be green and yellow for the side indicator light? straight green is only used between the flasher can and the indicator switch

black/white is ignition power, black blue is normally EFI power, so youve done well there

same for the rear, black white is ignition power and green only indicators, strange
