CA 89-93 Mustang 5.0 A9P EFI computer, and harness/computer combo

[mattt]

89-93 Mustang 5.0 mass air ECU A9P computer for sale. From an Auto trans Mustang but can be used in either application with a Bronco. Tested and verified good in my Bronco. Only Code 11 showing, which means all clear.

$165 shipped to non-remote delivery area via UPS.



Also have a factory 90 Mustang 5.0 EFI harness & matching A9P computer. The harness is complete...all 3 sections; EEC portion, injector harness, & O2 harness. The O2 harness has some chaffed wires that I was going to repair for sale. Injector harness has one clip broken on an injector plug, but I have a good injector plug to replace it with...I just haven't looked at how to R&R the injector plug yet. Other than those 2 minor issues, this harness is in very good condition given it's age. I'm geographically close to a harness "magician" if you want it re-worked, I could drop it with him to work his magic on it.

$325 shipped for the complete harness & A9P EEC computer.

Matt, I have an A9L mustang ECU in my EB and it works great. Rig is running a little rich though. Is that an odbe 1 scanner? How did you plug into your A9P for testing? Sorry still a nubie and have tons of dumb questions.

Yes, that code reader is OBD1 code reader & an OBD2 scan tool. It does both which is why I bought that one. For the OBD1 stuff all it does is tell me what codes the computer is throwing out there....no real time data like OBD2. I had to hook the A9P into my running Bronco, then hook up the code reader and run both KOEO & KOER tests. Have you pulled codes yet? That is your first step. The reader makes it easy, but you can also pull codes with a jumper wire and a light bulb.

How do you know it's rich?

You can just tell from the smell at idle. But it runs good. Long tube headers into 2" stainless exhaust all the way out. Not CAT so maybe I'm just smelling what a CAT would normally burn off.
