Hello I have been looking for a wiring harness for my 1986 rx7 nt and was wondering if anyone knows where i can buy a new one for a fairly cheap or a decent used one, i plan on doing a motor rebuild with a motor that has 225k on it, im afraid that while removing the harness that its going to crumble in my hands from poor care.

 

Good luck with that! There are two maybe three different engine wiring harnesses in the engine bay. These wiring harnesses are NLA from Mazda. You might want to checkout Rhineharts Auto Parts (Home), Rotary Resurrection (https://www.rotaryresurrection.com/), Catalina Auto Recycling (Catalina Auto Recycling) or Ebay, but Caveat Emptor. Let the buyer beware when buying used electrical parts
