I've managed to source connectors for the stock engine wiring harness for the early FI S30 and S130 cars. I'm just posting here to see if anyone else would be interested in a kit and I'll order in some extras. The kit 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. I'm redoing all the connectors on all my harnesses and I ordered in extra connectors for a few members on the forum who requested a kit. Price will be $50 shipped in US/Canada. There is well over $100 worth of connectors so this is a great deal. If you have a 280Z, 280ZX or engine swap EFI 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.

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. The replacement AFM connector includes the new body and clip as well as new pins to get rid of the many problems this connection causes.

I would also 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 and prevent future problems.

Kurk, great product works like a champ, keep up the good work. Thanx

I got an entire engine wiring harness from a place called Vines Auto in AL. They recycle BMWs there. For about $30, I got enough connectors to do two engines.

I can definately do harness repair. I would think shipping back and forth would be expensive though. Right now I'm making a custom wiring harness for S130 for plug and play MegaSquirt setup then I'll be developing an S30 kit as well.

I'd be interested if you make a MegaSquirt pnp harness to put a turbo L28 into my '75 280Z.

I'm pretty close to a finished product with the S130 harness. I'll get to the S30 harness when I get a chance and keep you guys posted.

For those waiting on backordered kits I have the S30/S130 kits in and I'll be doing an Z31 kit as well for those of you who have the Z31 ECU swap (or a Z31 ).

I would totally be in in this if it worked on my 73.

Just got some new connector kits in. I would like to donate the proceeds from the next two kits sold on this forum (minus $10 shipping) to World Vision - a charity I strongly believe in and have supported since I was a little kid. I would encourage you to consider supporting them as well and/or researching charitable organizations of your choice to make sure the majority of your donations go to those in need (Charity Navigator!).

Thank you so much for sourcing these.

Would like to buy a set for my 78 280z. How do I contact you?

Scratch that. I already got some.

You've already got one?

Is this kit still available?
