Datsun 240z To 280zx Wiring Harness Repair Kit - Ev1, Tps And Afm Connectors on 2040-parts.com

I've managed to source connectors for the stock engine wiring harness. It will include nine EV1 connectors for the fuel injectors, cold start valve, idle air and thermal switch, a three pin connector for the TPS and the seven pin AFM connector.  There is well over $100 worth of connectors so this is a great deal. If you have a 240Z, 260Z, 280Z or 280ZX and you haven't replaced the 30+ year old connectors on your car yet you need this kit! A lot of the problems on the car have to do with corroded or loose connectors. Cleaning the male side of the plugs is possible on the AFM, injectors, TPS, etc however cleaning the female side on the connector is difficult and doesn't often last. The reason is that the male connector is easily accessable and are usually solid brass. These can be cleaned/polished to new condition. The connector side is plated and the disimilar metals cause corrosion and the plating is destroyed in the process. Cleaning the corrosion is difficult because they are physically difficult to access and with the plated material missing the base material will quickly corrode and the problems will come back.

This version of the kit includes a AFM, TPS and 9 EV1 connectors, seals and pins.  These are an upgraded version of the stock connectors with a quick disconnect squeeze tab and weather proof seals.  Please contact the seller if you need any further help or have any questions.

A lot of the problems associated with the idle and running of the car are associated with the AFM connector. Often the clip from the connector is missing causing poor a poor connection which can cause intermittant faults which are often difficult to track down.

I would highly recomend replacing the stock negative battery cable with a heavy cable to the starter and one to the chassis. I also recomend a ground cable from the chassis where the battery cable mounts to the ECU and from the ECU to the ground point for all the sensors on the manifold near the Idle air valve. Replace all the connectors with this kit and you have an excellent base for your electronic fuel injection system.

Replacing your connectors isn't going to solve all your electrical problems but it will give you a good solid base and eliminate a lot of potential problems.
