wiring

OK,

I got the motor in and everything hooked up the carb, fuel lines , exaust-ext-- i removed the tpi computer and the wirring to the tpi from the car.

now here is the challenge when I turn the key on I have no power to my heating and air unit or fuel pump. I do have power to all the lites, radio-tape, and the coil. The fueses are good.

whats up with this 1987 TRans AM, I want it to go to paint so I can cruz it!


thanks in advance

Your fuel pump was relay-controlled by the TPI ECM, so you'll need to build a way to switch power to it without the ECM there.

Your heater/AC blower fan is powered by a big red wire off the TPI's engine harness, which you removed. You'll need to find the connector on the blower fan harness, and get a fused 12VDC feed to it.
