Hey all I have a 2000 OBS Z71 Tahoe that I am putting an LQ4 into. Whichever wiring solution I end up I need to be able to read the vin from the obd2 port under the dash.

I've read that I can reuse the original L31 harness by switching a few pins around on the ecm connector as well as adding a few wires. I'm aware the injector plugs will need adapters.

Is there an aftermarket solution for these add-on wires? I'll be using a 2005 Yukon PCM
