For a 1990 vert.



I need to find somewhere to get the wiring that goes to the MOP. The wiring has one connector that goes to the MOP, then it goes up the front of the engine and connects to the main harness near the alternator.



This length of wiring on my car has damaged connectors, and the wiring itself is starting to develop cracks from age.



I dont know where to go to get a replacement for this length of wiring with the connectors. I'd prefer to get a completely new replacement for it so I dont have any further problems from this wiring. Without correcting this issue my 1990 vert goes into limp home mode, at random. I've confirmed with a multimeter that the MOP is good and I'm loosing current in this length of wire intermittently.

MOP = metering oil pump, most people refer to it as the OMP = oil metering pump

I just call it what the FSM calls it. I would just do the wiring myself, but I can't find the right wiring connectors, and all the RX7's in the junkyards down here already have the wiring and engines removed... FML

If I can't find what I need I'll just have to get the Rtek mod and eliminate the damned thing entirely. But If I'm dishing out cash for that I'll probably just wait till I can get the stage 2 Rtek...

I had to purchase a new engine harness because the idiots I bought the car from hacked the harness apart. I purchased it from a guy online and it worked beautifully. It was about 350 bucks for mine because it's a TII but should be extremely less for a NA if your interested

The problem with that being I dont need the engine harness.



there are six wires, with a six pin connector on each end (it connects the MOP to the engine harness).



I can remove the wiring from the car by cutting a ziptie (holding it in place, and away from the belts), and unhooking the connectors from the MOP and wiring harness. Its a two maybe three foot length of wiring. It takes like two minutes to remove it.



I can get some pictures if that would help.



If I have to replace the entire harness (which I wouldn't use) to get this small length of wiring, it would be like having the adapter wiring for the radio mess up and having to replace the entire chassis harness to get the stock to aftermarket wiring adapter for the radio.



now on the other hand, if I provide pictures installed, and unistalled with measurements and they can make me this section of wiring, I'd be very interested in that.
