Do you have the 3.0L SHO? I looked at the wiring diagrams for the 94 3.0L's...the SHO is the only one that shows having the IMRC...is this that the diagram you need?? The other 3.0L's(normal and flex fuel) don't show an IMRC in the engine control diagrams.

Sorry, reading through the forums on the issue I'm having I might have the term wrong.

It's that relay control box at the radiator. And it is a 3.0L not an SHO or Flex Fuel.

I haven't received any replies on my other post, but searching through here I found a couple others had similar issues
with engine running rough or not at all. And with the key in ON position, the cooling fan and fuel pump are always on.

Turns out it may be a bad ground somewhere where PCM pin 40 and 60 tie together, and something about S114 and S115
connections. So I'm trying to locate a schematic that show those connections to help me trace it down and check/repair it.

Sorry if this is way more info than you wanted, my fingers just kept typing. :blush:

Thanks for your help!
