ECM Harness HELP!

OK, so i took it all out of the car, switching to carb.

Anyone know how to fix the lockup on the tranny and wire up the fuel pump.

And do i need anythign else of the harness.

And what are those 3 other plugs right in the dash with wires going to the ecm and the engine comp.???

Can re-wire the fuel pump relay to the igniton switch. Ignition on, fuel pump on.

As for the TCC there are several methods: rewire for lockup once in 4th (tranny harness), use a vacuum switch to activate, separate controller. Tranny board has some additional info on this.

The ECM harness plugs near the dash are for the VSS, SES, ALDL, Bat+, Ign, stuff like that.
