Wiring: ? about the plug that has the tach signal and PCM power.. Its a rectangle plus on my 99 harness. It houses the orange pcm power wire and the white tach wire(along with a few others) well after converting my harness last night I needed to remove those wires to splice them into the RX7 body harness. After removing all of them I was left with a gray/black wire which I traced back to Pin# 53 on the RED connector and its the SPARK RETARD SIGNAL. Does anyone know where this goes..or used to go on the LS1 Fbody?
