Hey guys, I've acquired and installed an MMCS (Mitsubishi Multi Communications System) into my TL VR-X. It came with a an adaptor plug to allow it to function properly in a Magna, but it keeps changing between inputs of its own accord (FM/AM/iPod) and will even turn itself back on if I turn it off. Anyone else done this or know what may be causing the issue?

Sounds like it's gaining a command to the wire that controls the change of input.

I know jarrad had a look at it all, did you guys have a wiring diagram, or did you guys just make sure there where no crossed wires?

No diagram unfortunately, we just cleaned up anywhere that had just been twisted together and soldered it instead

Id say find yourself a diagram, ask Hayden if he had one or where he got it. That or find out what car it came from and track down a workshop manual
