Megasquirt installment

any advice on how to hide the megasquirt where it supposed to be without messing up anything? I bought my fox with a ms abd its just laying on the passenger side. Its really stiff & won’t even move up. It kinda bothers me seeing the computer & all the wiring there.

Pull all that insulation out of the kick panel area where the stock ECU was and it should fit up there. With the dash out you will have more room to get it up there.

Did you try disconnecting the main harness, feeding the ecu up into the panel and then reconnecting it? The wiring out of the other end will need to just snake down the side to where you can reach it

When stuffed up in the kick panel area, the large grey harness connector should be facing down. Just in case you were trying to stuff it up there backwards.

Mine is in the factory location. Harness aimed down like John stated. Be careful of the vacuum line. You don't want to pinch it shut.


You have a nice rear end there Dave.

I also have the Pimp XS in mine, stock ecu location. I had to put it up in, and then connect the main harness.
