New member starting 4.6 swap in 90 notch

[WrazelDazzel]

New to the sight, have a 92 fox as my DD. Just bought a 90 notch that I am going to do a 4.6 swap in. Never done a mod swap before so I'm sure I'll need all the help I can get. Especially with some wiring. Reading other posts tho I feel like I'm in the right place.

Welcome to the site. You are in the right place, so make yourself at home. How deep are you going into the notch? Do you know what you want to do with it yet?

Thank you and I'm not wanting to go crazy but have a fun little car like my other. It was a a 2.3 car so I'm hunting parts now. I've already got the 4.6 out of a crown vic and wiring harness, fox length 8.8, UPR suspension, coilovers, tubular k-member for mod motor, all control arms, ect.

Sounds like you are well on your way. I'm looking forward to seeing the pics of it coming together.

 

[WrazelDazzel]

Thank you and yeah I will put some up the more I get into it. First I have to learn how to use the site!

My weak point was the wiring as well. I just spent the money and had a plug and play harness made. 4 wires to hook up and disables pats and it started right up.

Like a standalone harness or a jumper type of harness from the modular harness to te fox?

I wired mine kinda like a jumper an it was only 4 or 5 wires did it only using pinouts and fox repair manual and a buddys 98 GT to probe and check where things went and had it running within 2 hours! Its not as bad as everyone thinks. i also apparently wired past the PATS , i ran it one day by accident without the chip

Were you able to use fox gauges and stuff too? I'm assuming that you kept the stock fox dash harness.

welcome and hope you enjoy your stay.

 

[wtst91]

Yes I used fox dash,wiring, and gauges

wiring will also be the scary part for me also. never messed with it before. But I do have a complete harness from a 98 Cobra is storage with the car.

Wiring really depends on the motor you use. If you go with the earlier style cobra setup you have more options vs the newer mod setup w/ coil over plugs. Use the same PCM to match your wiring harness and motor.

The standalone setups are great but you spend more time tediously wiring everything together. For a cheaper option you can also use a a9p fox body pcm from a 5.0 and a distributor drive setup. I have one for sale if you are interested.

I really like the COP wiring. I'm not a fan of the dizzy setup. The coil pack setup from that 98 Cobra will work as good as any. There are plenty of dyno operators that can dial it in.

The wiring for mine wasn't too bad, just know exactly what you want to have in terms of traction control or anything else. Most of the wires come from the fuse box that comes with the mod motors or the two instrument cluster plugs. It helps a lot to have the connector diagrams from alldata along with the two files that I'm attaching (they're on the site, but very helpful if you haven't looked at them). If you need any specific connector pinouts let me know and I'll try my best to get you a copy.
It's basically figuring out if you need a wire or not, and if not take it out of the connector and remove the whole thing later. It's kinda a do it and figure out method because most of the time everyone's stuff is different or no one really answers quick enough.

Good luck and if you need any help, feel free to pm me, I was very lost before my swap too.
