Firewall plug wiring diagrams needed!

I am in the middle of my conversion to a 4.8L engine in my 1996 short box step side. I removed the old 4.3 V6 ECm and I still plan on using the v6 A/C (with Lextech's bracket) and the truck's original HVAC controls and anti-lock brakes. I wanted to remove the wires I am not using as opposed to snipping them off and waiting for a short to occur. Does anybosy have a wiring diagram to the 2 firewall plugs? One rectangle one on the passenger side and one square one under the brake booster on the driver''s side?
