This is to Rich Bryant,

Rich Bryant sir i have a request, please consider this diligently, i'm wondering if you'll build me a wiring harness for my dodge Omni, i have a 89 Daytona computer with a 14 pin and a sixty pin, i'm asking because power module went down for whatever reason, i called Cindy for one roughly three weeks ago and i still have not receive it i called her and she said she would look into the matter but she never called back, i saw someone selling one on facebook which he said he purchased from you, so i.'m wondering if you still have one lying around or if you would be so kind as to build me one. I'll give you a deposit, whatever you want, and make the final payment when you are finished. i've bought things from you before. but this is a special request. The car has map sensor under the hood, has four wire sensors on the throttle body, it has all the upgrades, the car can get, the power module just copped out on me!Thanks very much my friend, i await your response! Oh my name is Errol Golding!

So you want a smec harness, essentially a Super 60 harness since it's for an omni. I bet you could buy one if the price is right.

I can't imagine what a made from scratch harness would cost. 3k maybe? I have about 100 bucks in materials alone for the alternator subsection of the harness in my lancer now.

Are you going for a factory correct look, or something that an f1 car would have in it?

Errol,
Good luck trying to find a good used or NOS s-60 harness at this point. It sort of sounds like your wiring conversion has already been done? As Brian (cordes) alluded to I'm quite certain they're some floating around being squirreled away for future projects. A new s-60 harness will not be cheap, they weren't cheap ever!
Here is a picture of a rebuilt s-60 harness (with 4 wire o2 upgrade) getting ready for install.
Good luck with your project.

A 1989 Turbo Caravan underhood harness is a pretty good option for an Omni.

A 1988-89 Omni dash harness makes the van harness basically a plug and play.

Thanks
Randy
