Hey guys I’m doing a V-8 swap on a 2002 Chevy Astro. it already has the 4L60E transmission in the van and I want to put a 5.7 Vortec in it from a 1996 Silverado I have found a wiring harness by Howell wiring it is #HV57T can I use the PCM off of the 5.7 and wire my engine with this ?

The issue I see is your '96 PCM isn't going to play nice with your '02 transmission. The 4L60e evolved over time and the controls may be different. If you find that they are compatible, by all means use the '96 PCM. I would take the Silverado harness too.
