ECM Help
 

howdy everyone, i have a question that i am sure you can answer. I have been looking all over trying to find out how to find out what computer/ecm will work on my 1990 5.0. I am looking to upgrade to a Mustang Computer and i still have the speed density so i can't have the MAF computer. The motor and computer are from a 1990 crown vic. Where do i find a list of part #'s of computers that will work. I have found part #'s like 49L and 49P and even e6sf-12a650-m1b, but how do i know if these will work. Thanks everyone and sorry if i posted this in the wrong spot, but i can't get anyone to help.

THanks again

Aaron

A3M
 

I had SD and the FRPP MAF conversion kit I bought came with A3M EEC-IV processor, which is a remanufactured A9L. Most production MAF 5.0's have A9L's.

FRPP complete wiring harnesses for EEC-IV processors are part no.: M-12071-C302

the engine harness and controls package is M-12071-E302 for five-ohs and 351 Windsors.

Sensor and relay package: M-12071-D302
