Hi All,
Just curious, does anyone know where the actual ECM Connection is located at on a 1983 Z-28,with a 305 Engine.

Heck, I'd like to know too.

It's a flat 4-wire connector that comes from the base of the distributor and connects to a harness back by the firewall. It's often difficult to see, tucked down between things at the back of the engine.

Then you don't have an ECM connector anymore.

Completely wrong-headed, in my opinion.
