Does anyone know of the availability of an affordable adapter wiring harness to hookup the factory 5.0 EFI setup to a '67 Mustang factory harness? I know many firms offer modified harnesses, but most are well over $600!!!!! Several years ago, these harnesses appeared on the market, and the cost was almost justified due to the amount of time & effort involved in creating them. Just seems like the price should have softened by now, but places like Mustangs Plus want well over $700!!! Any alternatives???

I have an HP book titled Ford Windsor Small Block Performance. It has an entire chaper devoted to this conversion and they recommend a place called Windsor-Fox performance enginnering. I've never used them or anything but it sounds like they should have everything you need. They provide a "No Brainer" wiring harness complete with a 22 page instuction manual, and all critical wires and sensors are individualy marked. The only problem is that the book doesn't leave any contact info for the company. It says they have been doing it since 1991, so I would imagine they should have some cheap harnesses. A simple internet search should find the company though. I hope this helps some.

I found the contact info!

I installed a 88 5.0 in my 68 convertible about 8 years ago and used Windsor-Fox. I didn't buy the harness from them, instead I shipped my 88 harness to them and they modified it for approx. $300. They did a great job, BUT I had to buy a pile of other little expensive items to get everything right, I also had to do some fabrication of my own because at the time not too many companies sold items to help the swap. But now that it's done the car runs like a new Mustang, in a few weeks I'm trading my convertible for a 70 Mach1 (hopefully it doesn't fall through).

Keep looking for a wrecked doner late model mustang. I picked mine up for $800, sold $600 worth of parts, still have a nise T-5 to sell plus I got all the little parts that make it go well. As far as the electrical wiring goes, its very simple. If you know about basic electricity, you could do it. Heck, I bet Midlife could do it, its so easy. You dont need the fancy harness.

The '87-'93 Mustang wiring harness is basically self contained.
I used an '88 California harness for my conversion. If you can solder a bit, adapting this harness to many applications is trivial. I have used a '89 setup in a Volvo with no main harness modifications.
You can buy the Ford Motorsport EFI harness (basically a '92-'93 Mustang harness) for $200.
The no brainer harness is for those who are too paranoid of electrics, have too much money, or very little time. If you have a brain, you can do it yourself?

If I had to rely soley upon Windsor Fox for my conversion, I would have never attempted it as it would have been far too expensive for my taste.
