There is no fuel pump module on 94-98s lol.



Plan was to have the ms3 trigger the various functions of the ccrm.



This version of ms3 has relay controls in it. So it has AC, fan, and pump triggers.



If i wasnt deleting the stock engine bay efi harnesses, i was going to do an eec v plug to the ms3 plugs.

Got sick of fighting with 20+ year old wiring harnesses.


So i bought an ms3 gold box and harness lol.



Looking to delete on the stock pcm, run the efi components through the new harness and splice the ancillary controls from the ms3 into the pcm plug.



What all does the pcm control besides the obvious EFI stuff?

I cant believe my luck on this.



Cant buy a reman from anyone. Waste 3 weeks on that.



Waste another week burning money and time in a scrapyard.



Only to end up buying an ebay GUK2 for an outrageous price. On top of the money i burned all ready.


Fuuuuuuuuuuuuuuuuuuck

GUK2 box code
Ml2-872 hardware code

Well thats swell.


Fml


Knew i should have just bought the $200 ecu that i knew worked



Guess a 98 town car or vic ecu would be as equally useless

showing box code VTC5 hardware code mlc-411

Did a side by side comparison of my old j3 port and the current one.



Definitely not the connection.


Could use some input here. Still getting all coil circuits open mil


Still no tach



Car is extremely unhappy with it.

On the 3rd cleaning.



It starts more than once. At least



Still no tach, still missing, still running badly.

Threw errors for a, b, c, and d coil circuits


And acted like it didnt know what kind of injectors and maf it had.


Ran worse than the f150 pcm

So.



Did you know the vics and marquis came with cop's that year?


And mustangs didnt?


Doesnt seem like either would run a mustang right.
