Finally got around to putting in those 4thgen seats. Since the car doesn't have power seats originally, I'm just gonna run a wire from the fuse block to the power seats and solder in an inline fuse and a ground to the chasis. What size fuse for the seats? Thanks in advance.

 

on 87' firebirds, the power seat circuit gets power from the same 30 amp circuit breaker as the rear window defroster and power door locks. wiring diagram also shows a 10amp fuse inline between the main fuseblock and drivers seat.

 

I lucked out! I found wiring from a junked car with the ends intact. There's an accessory block behind the kick panel that this harness plugs into, no muss no fuss. I'm gonna add the inline fuse for extra protection.

 

Are two seperate circuits on the factory distribution block. The orange w/black stripe wires are for the power locks, power seats, and rear window defroster.

Other circuit on the block has pink wires and is for power windows and rear windsheild wiper.
