There are others Temps [and threads] available but this is similar to stock. The one for the gauge comes from an '80 Monza with a 2.5L I found this by searching Summits site for Monza with no filters other than gauges and lots of reading the numbers supplied.

http://www.summitracing.com/int/parts/s ... odel/monza I wired my Oil pressure switch in a few months back, but I had to come up with an idea for marking the wires for reconnection after a previous owner had, [or had done] cut the oil pressure plug wires for the fuel pump off to fix a faulty switch. Oh yes the cut them flush so there was no turning back, so while perusing Rock Auto's site I see a heading for connectors under electrical and click. and TaDa!
http://www.rockauto.com/catalog/moreinf ... 477&jpid=0 So when it shows up the wires or terminal aren't marked, so after a quick H-Body search I find the terminal layout. Now I have to come up with a way to mark these wires in Blue, Pink, and Purple I have Blue electrical tape and heat shrink but Pink and Purple I can't find anywhere. So while walking through the dollar store I spot some nail polish in all kinds of garish colours, only two bucks each and my wire marking worries are over. So while watching TV I pull out my Connector and Nail Polish, find my cheat sheet from H-Body mark my wires and the next day (Ok somewhat soon after) I proceed out to the car and hook it up with out fighting unmarked wires. May this give you ideas to solve your hard to reach/see wiring issues. Harry
