Is it the same as my 89 Iroc-Z?? My friend has an 85 GN and says the check engine light is on (he hasn't had it long). Do you just jump the terminals on the ALDL connector like I do on my Iroc?

I believe all of those connectors are the same for GM vehicles. I would suggest checking a reapir manual, or buying a code reader. They're quite cheap, and should work with any GM obd1 system. Oh yeah, and this thread'll be locked because it's not thirdgen. Try a GN forum..
