Another idea I'm throwing around for my Rx-7 is redoing a lot of the wiring. My connections are soldered and reliable, but there is so much hardwired crap that servicing stuff is kind of a pain, especially behind the radio area where I have a ton of wires for aftermarket gauges. So I've been looking around online trying to figure out how I can use OEM grade electrical plugs. Here is what I have come up with.

First I went directly to the Tyco electronics catalog (Tyco makes the ECU connectors on my 7) but that was pretty tough to navigate. I eventually found Ballenger Motorsports, which carries a TON of injector connectors, MAP sensor connectors, etc. -- the majority is GM/Dephi, but they also carry Bosch, Denso, and Tyco stuff. http://www.bmotorsports.com/



this is an OEM 4 pin plug (both male and female side), with all the pins and insulators. I could use this to make a quick disconnect for the 4 analog input wires (2 channel exhaust temp, wideband power and signal ground) I will be running to my datalogging system. Right now I have ghetto radioshack quick disconnects which look like crap and are already starting to come apart from repeated connections and disconnections.

As far as tools go, I am going to use this process: http://www.youtube.com/watch?v=KEm2PuHBt4Y but with a proper crimper (it's a very reasonable $29):

and then I will want proper pin extraction tools ($20 for the kit):

so that's the idea I've been throwing around, and honestly it's less expensive than I thought it would be (although the professional grade tools are like $300). It may be a while before I can mess with this stuff because I'm so behind on getting my motor together.

sounds like a great idea. hook me up with the tools when your done .

I used molex connectors for a harness once. They suck when you want to separate them, and are not waterproof.
