iv just about finished the wiring for my ea82t convertion when i released that the harness only has 3 wires for the dizzy. but the plug coming off the dizzy has 4 wires. what i think has happend is that iv got the non turbo mpi harness. Can the engine run properly with out the correct harness??
cheers jarrod

Is it a 4 plug or 3 plug ECU?

If its a 4 plug ecu/hotwire maf, the distributor is the same (has 4 wires) between turbo and non turbo mpfi.

As for 3 plug ecu/flapper maf, im insure how many wires go to the dizzy

ok its a 4 plug ecu
