Hey guys, I have a 2000 mustang that's becoming a dedicated track car. I'm trying to figure out if it's safe to completely remove the GEM. I can't even find a wiring diagram/pinout for it. Any info would be great.

Any info is great....well here’s mine!

I kept mine and just cut out everything I didn’t need. I wanted to keep windows and door locks, power mirrors, and that’s about it. Haven’t ran into issues yet when done properly.

Thanks for the replies. I want to have as little excess wiring as possible but I'm not ready to rewire the whole car. I'll be doing that eventually once this engine blows up (however long that takes).
I've been looking for a pdf version of the Haynes manual/etc so I can easily search for what I need, but I can't find one. But has anyone actually heard of problems when completely removing the GEM? Pats is already disabled so I'm not concerned about that.

Alright, so I got the book yesterday and got to work on the wiring today. I've removed all the wires I don't want but I was wondering if it was alright to rremove the light blue/white wire that's for ISO 9141, which connects to the OBDII. I know that this is so it can scan the body control module for errors, but if I remove this will it affect tuning the vehicle?
