I have a few questions about the LSX swap. The wiring done was not the greatest so i decided to redo it myself.

Does anyone have a 1989 firebird C100 5.7 TPI Bulkhead Diagram?

Also I have noticed that the vehicle will only start if i remove the Gauge fuse. What goes through this fuse that can prevent the car from starting?

 

Is VATS or something else wired into the Gauge fuse? It seems if i start the car with the fuse out, and then put it back in all gauges work like they should. But the car refuses to start with the gauge fuse in, The Brake bulb test comes on and all gauges test themselves - no ignition.

 

I have a factory service manual for my '89 GTA, if you don't get an answer within a reasonable period, I'll dig it out & see what I can find for ya. (Got family stuff to do tonight though...)

 

Not a problem man, i figured it out. Turned out the C207 Drk Blue Vats Ground was cut. Grounded it into the new harness and she fired right up. Thanks for the response though!
