Hello all, Been out awhile and come back with questions. Lol I’m going to pull a gt40 upper/lower intake tomorrow off a 96 exploder and was planning on getting ecm, harness, air intake tube with mafbto put on my 87 5.0ho I know the firing order is the same on the ho and w badged motors so I think it should work. I have a AOD right now, will I need the aode from the explorer to match the ecm?! Any and all input is appreciated ; anything I’m overlooking?
What year/model is the AOD that you have now, out of? Do you have an ECU that's controlling your '87 5.0 now? If so, why do you need the '96 ECM and harness? I believe the '96 Explorer has an AOD/E which is controlled by a TCM, which is controlled by the ECM.
I’ve got a ecm out of a 88 lx 5.0 and the AOD (54k orig mikes) a friend changed his car to 5 spd. My motors out of a 87 and speed density. I’m still gathering parts and don’t have the engine harness yet. I’m not sure what works with what
Ford went to m*** air in '88 for California only cars. In '89 they went m*** air in the rest of the country. It sounds like the '88 ECM and AOD you have, both came out of your friends Mustang. You need to get back with him and determine if his car is actually speed density or MAF. If it is MAF, you're golden! Just use your current '88 ECM and AOD and install a MAF. If it's speed density, you'll need an '89-'93 Mustang ECU which is designed for MAF. For an automatic trans it's an A9P. You'll also need the accompanying '89-'93 engine harness. An '89-'93 MAF would be good too. I'm unsure of a '96 Exploder MAF but I ***ume it would be the same. You should look into that. A '96 ECM and harness will not work for you and you certainly don't want the AOD/E. The GT40 intakes should be good though. Here's a pic of my '93 A9P ECM and accompanying engine wiring harness............
Here’s a pic of ecu. I’m just trying to get a ecu with harness or a harness that will fit mine. I’ve been unable to locate the harness for speed density and not knowledgeable enough to know what switches. I’m ok without maf just getting everything out of picnpull and thought that ecu with harness might work. Wasn’t sure if it would operate without the tcm hooked up. Thanks for all your info. This is my first efi swap and just trying to get everything to fit correct
JFYI, The '96 unit Evintho Mentioned wouldn't work is actually the first year for the OBDII operating system. Prior to '96, the system also used a separate ignition control module which became internal with the computer in '96. (possibly '97?)................at least for Lincolns.
Any '87-'93 Mustangs at your local PickNPull? If not, here's a harness............. https://www.ebay.com/itm/373807726037?hash=item5708ad3dd5:g:UmMAAOSwkZBhovCC And, don't start the project unless you have one of these.......... 1988 Mustang factory wiring diagram
Many years ago I installed an EFI 5.0 H.O. engine in my ‘33 coupe. Did this when the new EFI first came out, pre m*** air. No kits available then and used the mustang harness and ECM including all sensors and smog controls. Was a big job and car ran fine. Last year or so when thinking of converting to M*** Air, my friend Ron told me about the Holley Terminator X system. No, I don’t have an AOD but a C5 in the coupe and it all worked well. With that in mind, I don’t see a need for an AODE with your change. Suggest you take look at the Holly Terminator X as it worked really well for me. Easy to install and infinitely adjustable. I did have the car Dyno Tuned by a Holley Expert after installation and that was well worth the money. Good power and runs like a dream! Pics show the mess of wires we removed and then after finished. Bottom line is you will not need the M*** Air setup.
Thanks for all replies. I’ll be getting the harness evintho sent if it’s there this fri. That’s all I’ve been missing. I haven’t found any on eBay for awhile now that looked decent. Thanks evintho for sending that link.
Comparing the AOD to the AODE https://www.becontrols.com/aode.shtml the AODE is beefier internally so using the harness is a good play.
