What's up guys and gals, I'm new on the forum and I'm from Louisiana, I'm currently working on a swap into a 96 single cab and I'm really looking for help with how to I splice my old harness into my new harness so my gauges and everything work

 

welcome to site. What harness your trying to tie in? What the donor?

 

I'm trying to get all my basic gauges from my 96 Silverado tied into my 02 Avalanche harness, but I can't find a wording schematic anywhere except all data but I can't get access to it. I need to know what color wires from the LS harness I need to tie into what color original gauge wires for them to work properly.

 

on my square body chevy I have a 89 suburban harness I started with. I used a lot of what was there for pcm power(had 2 to old pcm) that's what new needed. I had fuel pump fuse already so used that to trigger relay. For temp and oil pressure I used the sbc senders. Just bought adapters on ebay. Speedometer should tie in as well. I also used the original hot wire to coil to power the key on/key run/cranking as it stays hot. I got a 95-05 cavalier under hood fuse box wired it in. 2 rows of fuses in it. I took apart made 1 row to the coil wire talked about, other row to positive battery constant power. I used the fuel pump relay in that box too. The way Lt1Swap.com wires in the relays and fuse blocks I didn't do. Instead all the wires connected to what I had or cavalier box. I think your truck probably has all curcuits needed, just figure it out.
