Ok I have an 88 7mgte. The previous owner put a new wiring harness in and the male connectors for the harness are yellow as well as the ecu plug ins. Now with that being said I just read another thread and it said something about the 89-92 having the yellow plugs? My quetion is what color plugs should my 88 7mgte have for the ecu connections and if it is wrong could it make my car run like dog crap?
