I am fixing some old wiring harness issues, specifically my temp gauge and wiring. PO had some issues with the gauge reading and installed a new after market gauge. In that wiring it looks like he clipped the old green wire (see photo) and then ran new wiring etc for the after market gauge. I am trying to figure out where the issue is (gauge, wire or sender). However, I can not tell where the original temp gauge wire plugged in on the connector. Essentially, which slot on the connector should the wire originally have gone into? Thanks.
