First question to all MK IV gurus:
I found the big control box in the passenger side foot box mounted inside to the top surface and i wonder what functions are implemented?
Answers found in the www: PartNr. E5ZF-12B567-AA is a engine ECU for carbed Mustangs......The 1985 Mustangs,only the 5.0/5 speed manual versions,were supposed to come with a Two Speed Accessory Drive System,which used a twin accessory drive setup,controlled by a computer and electrical clutch,to let all the driven units,alt. A/C, PS, run at half speed under different conditions,to save HP and extra fuel mileage.
The idea was withdrawn,before production. However,some cars got thru with all the wiring harness and the computer control box.
What I can see is that the wiper motor connects directly to the box, is anything else controlled by the box???
Second question:
I removed all emissions devices in the engine bay.
Will the wiring harness still work and the car operate according to ignition and other non engine bay related functions?
I don't want to change the wiring because of a possible rebuilt to original specs in the future, just create a new engine harness with less connectors.
