Wiring EFI harness to battery and alt Q?s

[ks65stang]

I'm gathering parts for a mass air EFI swap to my 289 (stock cam if possible) & T5, to perform late spring or early summer. I just purchased a 91 mustang upper and lower intake complete w/ fuel rails w/ the mustang stock injectors & a 1989 - 1993 mustang 5 0 mass air A9L computer & harness.

I still need to get a stock throttle body, mass air sensor, distributor (will swap gears), coil, injector harness, o2 sensors (o2 harness?) and fuel lines and pump setup ect.

My new questions are can I keep running my stock 289 alternator? Is there any special wiring issues with the stock alternator? Will some one educate me on wiring the harness to the battery? I have read I need to relocate the battery or run lengthened wires. I have also read something about relays?

Only mods I plan are headers till I get comfortable w/ EFI

Any links greatly appreciated, I have been reading on http://fordfuelinjection.com/

I’m also looking for CHEAP stock parts for this swap if you have them. I thank all of you for all your help and I will return the favor to other EFI nebies in the future.

You can get the stock parts real cheap off of ebay. Another cool thing you can do is get the parts powder coated... Post a list of the parts you are looking for... I may have them laying around...

I am currently stalled on my own EFI project. Have the parts I need, now I just need the time. I can fire it up as soon as I plumb the fuel system. I modifed a 95 GT harness for my car.

Anyway, you cannot use the stock distributor. You need a distributor from a late model 5.0L car. <93 is best because the TFI module is mounted directly to the housing. 94-95 will work but it has a remote TFI module so if you are buying used parts be sure you get that as well.

As far as wiring to the car all you should need is +12V Constant, +12V Run/Start, and - Ground

www.fordfuelinjection should have all the parts and info you need. Download the mustang harness manual from them as well. It is a good source of info for modifyinig and hooking up your own harness.

Did you weed out the unused wires from the harness, and did you use your stock alternator?

 

[68rustang]

The engine is a 93 Tbird long block, GT-40 lower, Exploder upper and tbody, homemade intake tube, summit long tube headers, and 3G alternator.

I'm not sure I remember what stock looked like

Oh, and yes I did weed out unused wires..
