Accelerator Pedal Sensor Wiring Damage - SOLVED

[PopoPackage2011]

Hey everyone,

It seems the wires got pulled out of the connector on my pedal sensor. (see images)
I see you can buy replacement pigtails, I am just wondering what color wire goes to which port? I will need to know what to resplice?

Or does it not matter?

Any help greatly appreciated...

I picked up a replacement pigtail, clips into sensor but wires are a different gauge. Crimping different gauge wires i'd assume is a no-no?

I tried fooling with existing wires and clip, it seems I got all the wires stuck back into the right holes but still giving me the same CEL/ Reduced Engine Power. Id also assume its a pain even with the right tool or impossible to repair the ripped out wires?

You could strip the wires and recrimp the proper terminals on, if there's enough length in the wire.
The proper crimp tool makes a nice precise crimp. I got mine in kit from ebay. It came with a selection of plugs/terminals.

But splicing a replacement pigtail is just as good, plus faster and cheaper.
Are the new wires on your pigtail thinner?

Pigtail wires thicker. I just tried crimping, same problem. Probably a bad crimp.

Are you referring to splicing with wire nuts?

Thicker pigtail will be fine.
I usually butt splice and heatshrink it..
(barrel style crimp connectors, dont get the cheap ones)

This must absolutely be done correctly. As in, correct wires to correct spots on the connector.
I had a busted wire near my Throttle body position sensor connector and crossed a wire replacing the connector with pigtail.
I even triple checked!!

Later on the dealership told me that fried my brand new pedal sensor. They switched it back, and installed a new pedal. I still have yet to pull it apart and verify that they did in fact correct the wiring.

Did you crimp it, solder it, or what was your method of getting those wires together? Also, did your new pigtail clip have larger wires coming out of it than the truck's harness?

Don’t worry about the wire sizes. Use the heat shrink solder butt connectors they sell now. I avoid crimp connectors whenever possible. Especially on these types of circuits/ harnesses.

Mine was soldered. This is one of the places you want the best connection possible. Agree with @89Suburban, the solder-melt shrink style are a great option. I probably would use those instead of soldering in the interior.

Agree again with 89suburban, wire size difference is ok. I'm pretty sure the GM genuine connector did have 16, while the harness had 18. So yes, it was bigger.
I would not use smaller wires on the connector than the harness, obviously, but stepping up is fine.
