Reverse light wiring help needed

Hey guys, I got some flush mount LED lights for the back bumper of my 19. Got them mounted up all nice to my standards. I went to tap them in from the 7 pin and read something online that said the purple wire was my reverse lights. I spliced into the purple and it's actually brake lights. Does anyone know what color the reverse light wire is on the factory 7 pin?

 

What I would do, but OSHA wouldn't recommend it:
- Assuming it's an auto ...
- Put it into reverse, engine running.
- set the parking brake hard.
- rig an test light, ground one wire.
- poke the other wire into various contacts in the trailer receptacle.
- when the test light comes on, you've got the correct contact.
The center contact should be your back-up lights.
Use this method at your own risk.

 

Center wire...

 

That's the easy part. The backs are a little offset from the front

 

Thanks for this, exactly what I was looking for.

 

Disconnect the T12
De-pin the terminal
Carefully remove the terminal from wire
Add smaller gauge wire (extra length)
Crimp both to new terminal
Insert into T12
Mate T12
tie/secure the wires to harness and at new connection LED's. No flopping around.

 

Worked like a charm. You Tha man @caribe makaira

 

Didya do the de-pin/re-pin wire add deal?

 

Anything special about that 280 series Metripack? Just a regular 280 it looks like (10-12g)?

 

Nothing special, just as you've noticed, larger gauge.

 

Cool. Learn something new everyday I knew those were Delphi, but I guess I never realized they were 280 series.
