I parted a 87 gmc and every wire coming thru the fire wall behind the pass head is not needed . You can remove that complete harness inside and out of the cab . It is a independent harness for the tbi system . Has nothing to do with the starter wire and other electrical to make your truck work . All of those wires comes from behind the drivers side fuse panel beside the steering column .
