Hi, first of all... I'm not the one working on my vette so I hope my question is clear. I know nothing about the subject.
I have a 1986 and have made many changes to the car. I ordered a chip from PCMforless but the guy working on my car is not sure about how to plug in that chip.
does it replaces the old chip?
Do I need to plug that new chip and the old one in also?
Anyone has clear info on the way to do it with the 86?
thanks a lot for your help, always appreciated. Maybe one day with all your help, I'll know what I am doing
There are instructions with pictures on the above install site. From what I remember the new chip plugs on the adapter and the stock chip then all that gets plugged into the computer.
