For an upcoming project I've grabbed EDIS6 modules from three different vehicles at the junkyard. They have three different part#'s and the label is three different colors as follows:

Mustang 3.8 Gray F4ZF-12K072-AC
Aerostar 4.0 Green F4ZF-12K072-BC
Ranger 4.0 Orange 91BB-12K072-BA

Is there any difference between these parts?

I was searching on this topic some more - came up with this...

I also have these two modules for an upcoming install, so I just did some bench testing with both to make sure they were both working and see what the difference was..

Identical test setup from one to the other, just unplugged the EDIS conenctor and changed modules, no other changes were made.

Despite what I have read around the Net, They *do* have different RPM capabilities from my testing.

The "Green" EDIS-6 (Part# F4SF-12A359-AB on mine) went up to 7600 Rpm before cutting out
The "Orange" EDIS-6 (Part# 91BB-12K072A-BA) went up to 8800 Rpm before cutting out.

Once the spark had stopped, the RPM had to be bought right back down to about 2000Rpm before they kicked back in and started sparking again, so if you hit the EDIS's RPM limit, you *will* know about it.. it wont just be a misfire at high-rpm.

There may be other differences with Dwell Times, Low RPM Multispark and so on, but it seems most people are mainly concerned with the High-RPM limits, so theres some verified data for you.


And just for reference, it seems there's also a yellow one - here's the full list...
Yellow 91BB-12K072-AA
Orange 91BB-12K072-BA
Grey F4ZF-12K072-AB
Green F4ZF-12K072-BB
