5.0L (1979-1995) MustangTechnical discussions on 5.0 Liter Mustangs within. This does not include the 5.0 from the 2011 Mustang GT. That information is in the 2005-1011 section.
Hi everyone, I am new to the forum. 😊 .... and i am in need of some help for my 86 mustang gt.... i need a wiring pinout of the ECU, what i want is a wiring diagram like in the pic below.... and before u say do your research, I already have.. I been spending 3 days looking everywhere all over the web for a wiring pinout of the ECU, and I can't finding anything on the 86-87 with speed density, the only wiring diagrams I find are for 89-93 gt, and their mostly about how to convert to maf, but I'm not trying to do that.. does anyone have a literal diagram of pinout on the ecu?....
I'm not seeing them either. No attachments, nor embedded images. Might have something to do with the forum limiting your permissions... I think there's a minimum post count you have to meet first.
In the meantime, maybe you can upload to a third-party image hosting service (like imgur, etc.) and let us know where we can view them.
Oh, ok.. I understand.. I appreciate you all trying to help.. but I came across this YouTube video that had the answers I need.... I hope it helps other pop too... https://youtu.be/mqx4Y6SKPos
Thank you wbrockstar... but I did find this one threw searching to, and it said it was for a 88-93 5.0 mustang gt..
Its not for a 88-93 for sure.Take a look at the iac valve wiring.86-88 models were the only years that came equipped with a diode wired into the iac valve harness.89+ models came equipped with a diode built into the iac valve instead.If the diagram was for 89-93 models,the diode wouldnt be there.The next thing is a lack of maf sensor wiring in the diagram.86-88 didnt have a maf sensor,except 88 California cars.If you saw a diagram labeled 88-93 & maf wiring is visible in it,its most likely a diagram for a California model,otherwise the maf wouldnt be present.The last visible item that rules this diagram out as being for a 89-93 model is the map sensor label.86-88 (map) 89-93 (bap).........
