Back in March i bought a 00' Escalade with 186,*** miles, 800-1000 miles later my bottom end shat the bed. Brought it to a buddies house, pulled the 350, "dropped in" a LSX 5.3l out of a about 00' Silverado. Brought it to another buddies house for wiring. Now I am running both computers. The 350 computer is running the body and 4wd (so i think), and the LS computer is running the engine.
My dash engine temp gauge isn't working and am getting an ECT sensor code from the LS computer along with a TPS code from the 350's computer. Now I pulled almost every wire from the 350's harness that had anything to do with the engine running (we spliced in a "few" things for all my gauges to work) so i have no clue why just TPS is popping up and not everything else.
Lastly, my 4WD doesn't work. I turn the key, all the lights on the switch light up and then go out and that's it. I've been trying to do some research, a lot people said it was the switch in the dash or the front diff and rear diff solenoid/actuator. I've so far replaced the dash switch ($60) and front actuator ($180) with no luck. I talked to my dad who's a GM mechanic of 20+ years and he said it's obviously not getting power so start from there.
I also cannot find a wiring diagram for any of the connectors in the firewall, ie: the big one behind the fuse box going into the drivers side wall and the passenger side one that's underneath the coolant reservoir.
This is very frustrating and am just looking for some help or hints. My tuner said he rather not tune it with the 4WD not working because he said last time he did a tune like this he got stranded in neutral away from his shop.
Feel free to text me or call at a reasonable hour as I'm located on the east coast

I'm about to do things the hard way and pull both harnesses tomorrow and start chasing wires. But before that I'm going to get a light tester and see if the 4wd connectors are even getting power.
