well i just did my gte swap, now when i turn my head lights to the off position, the runners and dash lights will go off, just not the head lights. when we unplug the relay you can hear it click, and when we plug it back in, it cliks again and they just go back on. also, i am getting no tach reading, im not sure if they are related.

thankyou

im not sure what year the harness is forom, it was just the engine wiring harness no the interior harness, but if it was a pre 89, what would be the fix for that ?

You would need to find a 89+ harness for the engine and the correct sensors for the harness. Does the engine harness have Yellow or Gray ECU/ Dash plugs? If it has Yellow, then its a pre-89 harness, if its Gray then it is a 89+ harness.

As for the tach, the NA vs Turbo have different ignition systems, the NA uses a distributor and the Turbo uses a Cam Position Sensor so to fix the tach you will need to find your self a factory Turbo tach, or pull your tach out and replace some resistors.

Good luck.
