When this says SWAP INTO ANY VEHICLE, I am looking to marry the 4.6 SOHC engine harness to teh 1988 chassis wiring. Will this garness enable me to do that?

I believe the harness above is only to get the vehicle started. You can use your existing 88 chassis wiring for all your lightning needs.

Thanks for the information. I have all the wiring for lights done, I am now trying to marry the main. If this harness will let me plug n play, this is exactly what I am looking for. Sorry, I shopuld have specified that when I wrote the last time. Thanks again.

Well thus far I am disappointed in these guys. I left a message and an email asking the status of my order and both times no reply. I Called just under 3 weeks ago ordered my harness with an 05+ MAF harness. They told me no problem, 2-3 weeks and we will ship it out. 3 weeks now and no shipping info received this week. I called them and asked the status of the harness. I was told that there is a 2-3 week wait for the harness. Wait; wasn't there a 2-3 week wait from when I first ordered? I asked if there was any way to expedite my order because my car is complete and I'm just waiting on the harness., the response was no and something mumbled about build time. I can understand small delays, a few days, a week, but by the sounds of it they haven't even started my harness.

The called detail and there harness in stock and ready to ship within 48 hours. I'm looking for reviews for people who have used the harness. If the detail zone kit is good and RJM cannot step up my order then I may cancel the RJM and go with the detail zone.

I will post my results in the days to come.

For what you paid, I would cancel the order and go with someone else. It sounds like their customer service is TERRIBLE!

I do not mind paying top shelf prices if the product is backed by top shelf service!

For the money you spent, you could have used your factory fox computer for the fuel side and went with an msd mod box for the COP.

In the time frame they told you it would be done, you could have made your own harness or paid someone locally to do it for you.

I hope it works out for you! Believe me when I say that I am more then willing to share your experience with this company to others online and the tracks that I race at.

I have an entire Mach 1 harness (total car) but I lack the time right now to build it myself. Its the start of the busy season at work. Doing 4 hours OT a day and 11-12 hours sat. Play with the kids on Sat, then not sleep tp work on the car lol.

 

[Svt Fox]

No wonder you paid your hard earned money for a harness you thought would be completed in a timely manner.

 

[Speedtospare]

Yeah, sometimes you need to pay to play lol. I am sticking with the harness for now. I just hope the order is correct.

Harness is in the car and working but it required modifications. A few passenger side injector plugs were too short. There was no plugin connection for the alternator, the harness itself should have been made neater near the back of the motor, its a birds next. The harness just feels like it was designed to work with the motor but not made to fit the motor. There were a few issues and I am peeved about but it does work. IMO for a $900.oo harness it sound be plug and play and require no modifications, ne neat and fit perfectly. 3/5 stars rating.

Hell based on your comments, I wouldn't have even given it a 3.

 

[Speedtospare]

Yeah, I would have stuck with the stock harness if I know I would be modifying it that much

See if you can recover some of your money back because you "had to pay someone to modify it to work" wink, wink

 

[Speedtospare]

Its hard to get a hold of them on the phone. I have to call them back and find out a few things.

Well the summer is over and I would like to place my review. The harness never gave me any trouble over the summer. The car runs great with no issues. Plain and simple; after modifying the harness it fits and works well. The support from this company is the worst I have ever seen. No returned calls. No return emails. I even placed reviews on there website on the harness review page and still no reply. For almost $1000.00 with shipping and duties I expect more.

Edit: One problem for me is that my blue tooth OBD2 connector no longer work in the supplied port. I use a program on my tablet called Torque. It gives me all the info on what my cars vital stats are.

I would use the detail zone harness over this one next time.

 

[Svt Fox]

Sooo glad I went with an OEM harness.

 

[ModFoxMustangs]

Sorry to hear that i also got the detail zone and very happy..

Well a slight turn of events. After posting this I decided to make another phone call, I left a message inquiring about the bluetooth and they actually returned my call. Well I'll be damned. They even game me the pinout over the phone. and told me what whire I need to use to hook up my tach adapter.

I really want to do a DOHC swap, but I am terrified of the wiring and electrical. I need a place where I can bet a step by step... cause now I don't wanna get into it, get frustrated and then quit the project.
