Ijust put the wc borg warner t5 in my 85 iroc cant seem to wire up the revurs lights to the switch in the trans iv tried all wires and still notging, fuses are food and it all worked when the 700r4 was in

 

In 85 the reverse light wiring is different for each different type of Car/Engine combo.

All Auto's uses the same wiring, but Manual cars were all different. All cars got reverse light power from a dark blue wire leading from the TURN/B-U fuse. That blue wire then led to the Turn Flasher.

For Autos that Blue wire from the flasher then led to the PN switch

For 4-Cyl T5 cars that Blue wire from the flasher leads to the back-up switch in the tranny thru the C221 connector. ( Black plug, 6 pins near C207 )

For 6-Cyl T5 cars that Blue wire from the flasher leads to the back-up switch in the tranny thru the C100 connector. ( Firewall connector on drivers side. )

For 8-Cyl T5 cars that Blue wire from the flasher leads to the back-up switch in the tranny thru the C207 connector. ( Dash-to-ECM connectors )



Here is what is important to you:

The eaisest way ( IMO ) the get the back-up lights working again after a conversion is to run the Blue and Green wires from the tranny switch thru the hole in the floor for the shifter and Tap/Splice/Solder them to the Blue and Green wires at the original auto PN switch.

Hope that helps !

 

Cool, thank you! Ill try it as sion as im out of work and let you know how it turns out

 

Thats the easiest solution for ALL auto to manual swaps. The same connector also houses the starter solenoid wires for the clutch safety switch any manual conversion SHOULD be adding
