My understanding is the temp and fuel gauges are set up with one wire going to a switched 12v and the other to the sending units. Is this correct? thanks Doug

Not sure why they are not moving to the right as there is power to them yet touching the sender wire to grnd did nothing. Can you tell me which post is the 12v and which is the sending post looking it from the back. Doug | | |
