I just pulled my computer to get the tune checked, and when I took of the terminal connectors, the blue plastic inside was in pieces. The red side is intact. Do I need to replace the blue plastic piece, or not worry about it?
Well I found out that these are pin guides or pin protectors. They go over the pins, on the connector, that attaches to the computer. Do they have to be on? The local chevy dealers have no idea what they are or where to get them.
