Started putting a 95 harness in a friend's 87 (I know shoulda used the FOX harness but this is what he had) and I'm wondering where to pick up power for the ECU. I have all of the actuators connected just wondering what I might need to do for power and grounds.

On a fox, the KAM gets power from the starter solenoid (there's a fusible link in series. 20 gauge, IIRC). The computer has a dedicated ground that attaches to the driver side fender next to the battery. Good luck.
