Speed sensor cable?
You will also need the clutch cable, ELD and a CRX HF VSS. I just finished wiring my '86 CRX SI for my '88/'89 D16A1 and having the Integra factory wiring diagram (the FACTORY diagram, not the Hanes or Chiltons diagram) was essential!!!!!!(!!!!!) Also having the Integra wiring from the engine to the ECU was EXTREMELY helpful!!!!!!(!!!!![!!!!!]) The A and C connectors at the ECU on the CRX are almost identical to the Teg so you can just swap some pins around to make things work, but I ended up using the Teg B connector and all the wires attached to it since this is where most of the wiring changes were made from the factory. Just to clarify, I used a junk yard '88/'89 Integra engine wiring harness and my stock '86 SI main harness, supplemented with parts of the '88/'89 Teg main harness.
