probably under teh dash, pointing down at the carpet somewhere around the steering column...that's where it is on my 98, although it's OBDII, I don't see why they plug locations would change...

I think it's under the hood, near the center of the firewall about where the PCM is located.
Should be a black L shaped connector

I agree its under the hood.You will need the chrysler adapter also to hook into it.Rocky

There were a bunch of different procedures for resetting the maint light.Some had a switch some a battery had to be replaced.You need to find out thru All Data or Mitchells etc how to reset it.Rocky

Did my 89 with an old snap-on scanner. Took a while to find the darn set-up, and had to do it twice for it to take.
Good Luck!

I have an actron scanner. What needed to be done with the snap on scanner to reset it? I can reset/clear the codes but not the maintanence light....

I had to do a friend's Ram truck too, and can't remember the exact process.
It was not in the data and codes menu, it was in a separate area.

The snap on scanners can reset those,I think it was under the special functions section.That is a seperate unit from main computer,Turns one by pre determined time/miliege.Supposed to have emission system checked for proper working.(eg)egr valve, cat conv,vacuum hoses,etc.I can look on mitchell wednesday for procedure.Some needed the module replaced,some had a 9v battery to replace,some even had a button you just push.unit is behind the instrument cluster/dash.Light has NO indication of an actuall problem.

90 I believe was a battery replace.They used probally 4 or 5 different setups in those years.I do remember some had a switch ubder the dash that needed flipped and some had a button that needed pushed in.Its in All Data how to reset.Id do a Google search and see what it says.Rocky
