On my 1982 US car.....I have pretty much figured out and repaired all my wiring and lighting issues with the car other than the backup lights.Looking at the WSM schematics and what I actually have back at my 4 prong plug ,nothing really matches as the PO has been in here also! At Connector T4a in the spare tire compartment I have this....... at position 2 I have 2 brown wires on 1 side....1 comes out to a weird connector ( PO installed?) ,then loops back around and is tied into 2 gray/brown wires...1 leading back to the wiring loom and 1 leading back to position 3 on the same terminal ( T4a position 3) . Can anyone make out why that is run like that and how it should be? I,m not seeing any unused or unconnected wires back there and everything works except back-up lights and any indicators on the dash and my shift light. Its an automatic car. I feel something has been F...ed up back there,just not sure why and how to fix it. Thanks ahead ! Chuck

ps...also, the 6 pin terminal next to it ( T6c ) at position 3 has a black/blue wire coming in one side and nothing come off the other side?! . what the....?

 

Do the backup lights and dash gear indicator work when the lights are on?

 

Gaz, they dont. I was suspecting the switch on the tranny but when I took a look at the terminals in the back ,things looked a little wonky. I repaired one of the wires to get my brake lites up and running but it looks like the PO put that connector in there for who know why.
