99 4wd 4d auto with factory fit keyless entry,more on my problem.Having had the car on a tech 2 scanner, it came up with code u1064 ,loss of communication with BCM.
Does anyone know where the the BCM is located on this truck, thanks anybody.

Check the 10A TBC fuse in the underhood fuse block. Also taped to the harness going into the body relay block (huge connector, front of dash, your left knee (or maybe a bit more to the left) would hit it if the dash wasn't there) is a splice pack with 11 different colored wires tied together (in the schematic and diagrams they show it outside the harness anyhow) That splice pack is where all the modules tie together for communication. Diagnostics say to start there and look for a bad connection going to the offending module. (light green wire goes to the BCM)
