1990 7MGE Coil Ignitor compatable with 1985 5MGE?
Need a little help from the GURU'S..
I've done research & have found the part number for a 1990 7MGE Coil Ignitor to be interchangeable with a 1985 5MGE Coil Ignitor.
The only difference I've found is a single plug from ignitor for 7MGE & 4 plugs from ignitor on 5MGE.
So the question is, will a ignitor from a 1990 7MGE work on a 1985 5MGE ?
Are the 2 ignitors calibrated differently for ignition timing ?
FYI, new coil ignitor is 512.00 from Oriely Auto Parts. I got one from a pick and pull for 38.00$ !!!
Thanks for the input

Interesting you post this right now. I'm actually looking to do a tune up on my 6MGE, and one of the things I was looking at was a new performance coil. 83CelWa has modified his, and he says it's a good electrical boost. His P/N is for the Streetfire Ford TFI Performance Coil, #5527. I'm going to be doing this mod either this weekend or next (transmission issues take precedence in this case).
I'm interested in what's said about the 7M coil though. Maybe it's better than the S/F.
Thanks for the post!

Im actually running a MSD Blaster SS coil & stock ignitor & did not notice any improvements.
Still looking for someone to chime in about compatibility between coil ingnitor for a 1990 NA 7MGE & 1985 NA 5MGE.
Are the two ignitors calibrated differently?
Thanks again every one.

Bump for testing 1990 NA mk3 ignitor on 1985 mk2, Is it a good idea?

A coil is a coil. Pretty sure the igniters work the same, so you'd just have to repin the plugs and try it out.

Good deal & thanks for the input, I will post the results on Friday.
If a stock re-pinned N/A MK3 ignitor works with the MK2 stock ignition i will have saved lots of cash by not buying new oe.
Any other technical opinions?

The '85 has many plugs off of it.
I believe your '90 Mk3 has a single square type plug like this one below.
Be careful you don't short the wrong wire. So many bad things can happen.

I actually used the links in your sig to find the pin out diagrams for each year. Thanks for the info which I printed & gave to the shop this afternoon.
The pictures your referencing have the part number of the coil I pulled from pick n pull. -0931 (93) The car has been in the shop for electrical issues & from over heating then blowing my cam seals last summer (113 outside).
Hopefully they will do the re-pinning & testing mk3 igniter on my mk2 ths weekend.
