94 4L Engine Swap Wiring Problem

Ken,
Sure do wish it was that simple....The AC compressor wire is a flat connector that fits right up front on the AC. The Connector I'm struggling with is round with female pin ends Connector with red center and two wires.....I feel so stupid because its a short portion of the harness right near the back of the Power Steering Pump but I'll be darned if I can figure out where it connects!?!?!!?

That's great! I assume that the starter is working correctly now too.

Bob,
Yep the EGR Version Wiring Harness is NOT compatible with the Non EGR engine. After switching over to the old Wiring Harnass and removing the EGR stuff putting the Air Intake from the old engine on and changing the one Exhaust manifold....The Starter worked right off and the engine sounds great....before when I hot wired it it was not running right on all 6.....So the advice on the Forum was "RIGHT ON"
