Default 2003 LQ4 Harness diagram

Anyone got one or can get me one? Or maybe the pinout? Thanks.

I just reworked my 2002 Silverado LQ4 harness with the help of this.

Just use any 99-02 F car pinout. Its the same for the truck. Well, it was the same for 2002.

I would recommend getting one of the GM service DVDs. There are always people on here and on Ebay selling them and they usually go for $20 to $25. It will have all the wiring diagrams you need. I believe they are actually referred to as GM ESi.

I bought a subscription to alldata for the 02 escalade I used in my swap. It had all of the diagrams you would need. Send me an email and I can send them to you. I used the dbw but don't know if anything changed for 03.
