What year is your harness? There's quite a few guys on this sit that have done the swap. Myself included.

the harness came from a 05 chevy work van with the motor, i was able to connect the basic plugs.its came down to the wires going to the main fuse box in the engine bay, i not sure if i need to get the smae year fuse box that came with that motor or is there a way around that if you have any tips or advice i would really appreciate it
You need a 99-02 truck harness. That's it. No if, no buts. 99-02 truck harness.

Ok cool I'm gona try and get one I'll keep you postedOriginally Posted by Frenchy
finally got the harness in with no problem the only thing i had to swap out was the oil pressure sensor and the AC pressure switch also i ended up geting the 99-02 computer.... started right up....for abot two seconds.still need to install the pressure switch. does any body know if i need to flash the PCM or the body control module
if it started and ran for two seconds and then died you most likely need to have the VATS/Passkey disabled in the tune.
