There are two different types of computers and harnesses between 99-07. We need to know which one you are using, 99-02 or 03-07.

Oil pressure sensor is different. IIRC the AC compressor is different. The 99-02 harness doesn’t match up with the 03-07 PCM and vice versa

I know yall have plenty junkyards in Texas bro, go to the junkyard you will find those everywhere for little to nothing. When my truck caught fire a while back I got everything from the junkyard for under 100 bucks. Including fuse box and all the plastic pieces under the hood.

I will be using an aftermarket oil pressure sensor as I build my own standalone harnesses. I do currently have a 411 computer which came off of a 01-02 dbc engine but I have no harness.

Then you will want a 99-02 harness. The 03-07 harness has a completely different PCM pinout.

I have a new harness from Alabama LS Swap. It has the Red/Blue plugs and I had him put EV6 injector plugs on it. Also have the Red/Blue PCM that has either cable or DBW capability. I changed engine setup and will be using a E38 computer and harness.
$250.00 plus shipping and paypal fees for the harness and PCM.
