L92 wiring harness help!!! Guys, got an L92 wiring harness off an 08 escalade that I'm putting on my LY6. I've got the wiring diagram and found 95% of the connectors.
There's a big 20+ pin harness that connects to the gas pedal somehow. I've got the pins that go to it but not connecting that to gas pedal. On that connector is also two data line wires, and three other wire that go to a connector that's on the harness that's near the MAF.
I can't find what that 3 pin connector connects to or where that 20 pin connector goes because I don't have the other end. It's a 3 pin pink/brown/white that goes to that 20 pin connector.
Any thoughts what that is, or what the 20+ connector connects to?

That connector would go to your cabin harness...which you probably will not use.
I just did my L92...not in the vehicle yet.
I depinned that connector completely. I did have a tahoe harness to yank the pedal connector off of and I extended the wires on that and connected directly to the ecu connector.
Does that make sense. Basically you just ditch the middle man.
There are other signals coming through that coupler. I think the brake switch and can lines(for the DLC connector) is on there as well.

Just trace the wires in that connector back to the ecu connectors and use the L92 wiring diagrams to make it make sense.
Well, I was gonna post a link and cannot find it. If you pm me your email I'll send the diagrams to you.

It's the connector that splits out of the main harness with the Passenger O2s and the MAF sensor. There is also a blue and brown/white connector that go back into that cabin harness that I have no idea where it goes. Other than that, my wire diet is done

Brake switch is light blue with white stripe.
PM your email, I'll send you the 5 page 07 Escalade engine harness diagram I have.

Found it on Rockauto....they have pics of the connectors.
I was trying to figure them out for the longest as well.
The two pin(blue and black/wht) connector to be the same as the compressor clutch cycle switch.
The three pin(pink, brown, white) is the "battery connector". I assume its a battery charge indicator. It would shut the electrical system off if the battery started getting too low.
