I have a 89 GT that i didnt know to much about when i bought it. the guy really didnt know what was done to it, but anyway i had this offroad/stock switch under my steering wheel and thought it was somehow connected near the radio so i thought nothing of it... then i started to change my heater core and seen the computer.. it has an EFI SYSTEMS INC. sticker and says 304 next to it. then i followed the wire and it went to that switch i was wondering if anyone knew what it could be, i looked on there sight and they have a couple of things and im not really sure what it is.
