On the 03 harenss I spliced the wires from C2 on the Park/ Neutral switch. Which is white, gray, yellow and black and white wires to were the 97 wires went to the fire wall under the evap. On C1 at the trans (looking at the connector veiw) A to G, B to B, C to C, D to D, E to E, F to F. G to the starter relay.

got this info from a member in here wayoung.. he did a 4.8 into a 97 burb. im doing something similar and im also at the wiring part of the swap. i already modified the facory harness just haven't had a chance to install it.

i went through and relabled this for my own benefit later lol the colors are the wires from my 97 that i need to chase down and pin to the 02 ECM
