Where does the underhood fuse block get it's power from? I'm trying to wire up my '88 Trans Am with a '94 LT1/T56 and the motor came with the underhood fuse block harness also.
The PCM gets the power for the injectors from the 2 7.5 Amp fuses in the underhood fuse block, and power from the Ignition fuse (10 amp) too. I have the 4th gen C100 connected to the engine harness I just don't know where the power will come from.
There's a lot of fat red wires that go to the relays in the underhood fuse block....do these fuses (9,10,and 11) get power from those red wires too?
