swaping a lt1 into a 89 trans am few questions
I'm in the middle of doing my first Lt1 swap to a 89 trans am and have a few questions.. I bought a donor car to do this swap it was a complete 94 camaro z28.. we are swapping the motor, trans, and rear end.. My question are...
What wires do I need to use to power the new pcm?
What wires do I need to splice to get the speedo to work?
And for the rear end the trans am has drum brakes the new rear end has disk brakes. Can I just use a proportioning valve off a third gen with rear disks?
Thanks for the help

It was in the sticky in the Engine Swap forum, but not in the LTx and LSx sub-forum. My bad.
