Coolant sensor and coolant gauge help

[JMiller]

I just completely re-loomed my harness on my 92. Mine has a single black wire that runs over top of the driver side valve cover tying into the alternator wires and then the a/c wire and other temporary sensor wire. All of those wires run parallel to the passenger side valve cover to the fire wall.

Just rubbed a little spit on my wire, it is green not black.

So its a single dark green wire that goes from the sensor, ties into the wiring harness for the alt then joins the AC harness as well? any pics by chance?

 

[nicklatech]

yes, picture with plug color would be great

does the plug have two wires ? i know the sensor has one wire, but i better ask.

Sorry about the duplicates. There are two locations on the firewall where wires come through one on each side. Most likely the green wire will trace back to the plug on drivers side of the firewall. Not positive on that but it's logical sense that is closest to the gauges.

does that temp sensor plug on the head have a blue clip?

That was seriously the most PITA thing I have done so far. If you decide to do it, take lots of pictures of how everything is routed before you take anything apart. I took zero pictures and regretted it everytime I had to reroute everything until it all fit.
