Convert your speed density system to mass air with this wiring harness. Just connect this harness to your new MAF sensor (not included) and simply plug into your existing speed density wiring harness that connects to the mass air ECM (not included). No cutting wires.

MAF sensor - I know is not included - I'll get one

Mass Air ECM - Not included, but does my SD car already have it or do i have to get that also?

Is there anything else that i definately need to complete my conversion?? Thanks alot, i know theres been a million questions on these, but i want my exact question answered. Do i have an ECM or do i need one, where does it go, how much is it, and can i still get it from a ford dealership parts department??

THANKS GUYS

The computers ARE different. You will need an A9P or A9L computer. You can usually get them on Ebay for around $100.

I Did The Same Conversion On My 87 , I Had To Run Some Wiring With Fuel Pump And Change Some Wires In The Pin Postions On The Eec Harness This Is Posted All Over The Web For The Conversion. Try Lasota Racing I Beleive They Have Good Photos . I think it was the pink wire under the seat to the relay was cut and ran to the eec harness been a year ago

You 100% NEED a new computer. A SD computer will not work with a MAF setup, period.
