ok if you got a test light the pink wire should have voltage with the key on if it does light then the center terminal is the ground hook the test light from the center to the pink wire if it lights both wires are good if you dont have access to a test light a volt meter can be used the other option is to pull on each wire one at a time neer the plastic on the plug that is where they usually break also make sure all air cleaner tubes are tight
