4 pin and 7 pin ficm

[DT620]

Is there any difference in the two? Or can they both be used on a 2004? Just need some info not too familiar with it. Thanks guys

Mine has had both in it. I just had my FICM replaced with a new one at Ford last week so my '04 has the new style now

Yes you can use either one in any 6.0 however the half shells aren't compatible with each other for obvious reasons lol one has 7 pins and the other has 4 pins. The only thing is if you have a 4 pin and put a 7 pin in your truck it will throw a soft code for FICM software programming incompatibility until the new FICM is flashed to match the PCM programming.

Is there any advantage of having a 7 pin over a 4 pin?

Nope.......

Seven is suppose to be a lucky number maybe Ford was hoping it would rub off on their dang FICM?

Well my cts came in the big brown truck last night and just got it hooked up. The lowest the voltage got down to was 47.5 so I'm guessing its not the ficm going out.

I've had both on my truck with no difference in performance. Mine has never thrown a soft code either.

As far as the 4pin and 7pin I dont think one is better than the other. But....

There are differences in the programming on the logic side of the board and that can be much different between FICM's depending on the last time it was flashed.

Also there are 15amp and 30amp logic boards and that can make some drivability difference as well.

There actually is an advantage to having a 7 pin ficm.

Do you guys want to know?
