Funky Conversion Questions

[Dupree, Robert A.]

You want to swap?  I'm game!  I saw the tranny that was pulled off the
engine.
Certainly would make my life easier.

		Steve,
			Just saw that you have a 95 Camaro PCM programmed
for the 4L60E. I have a 95
		Camaro PCM from a 6 speed car. I was going to have GM
reprogram it. The PCM's
		are the same just a firmware difference. Where are you
located? Maybe we should
		swap.

			I made up a table showing the pinout of the four
major engine harness
		connectors. It has the Pin#, Color, function, and GM F-body
page reference for
		each pin. I also just got the Forward lamp harness, and I am
using it for the
		relay panel and connecors.
