Hi there guys, I am in need of some advice, I have a Complete Wire Harness out of a 1993 MAF Mustang and trying to convert my 87 Stang to MAF. Well I dont want to strip my car to intasll a complete harness, so I was wondering if i could simply trace the MAF conector wires and unplug them off the 93 harmess and run them to my existing harnes and plug them in like with the Granatelli Harness i saw for sale?

I already have the Computer as well. If the above is possible is there any thing else i should know before i do this. Maybe a diagram on the placement of the pins could help me to.
Thanks Matt

need to know which wires are being refered to in that article i have a red, black, blue/orange and a orange/blue.

a. The Power (+) wire from the MAF meter harness needs to be spliced into the existing red wire in position #37 of the EEC connector.
b. The Ground (-) wire from the MAF meter harness needs to be spliced into the existing black/green wire in position #40 or #60 of the EEC connector.
c. The Signal (-) wire from the MAF meter harness needs an EEC pin which then gets inserted into position #9 of the EEC connector.
d. The Signal (+) wire from the MAF meter harness needs an EEC pin which then gets inserted into position #50 of the EEC connector.

The MAF connections do not exist in the 87 harness. You will need to add wires with pins to make it work.

See Ford Fuel Injection EEC Connector for some help with removing and installing the wires and their connector pins.
