First you will want to connect an 18 gauge wire to the Temp Sender mounted on your vehicle. You will then route the wire through the firewall into the passenger compartment where the Temperature Gauge is mounted and attach the Temp Sender wire to the terminal marked (S) on the gauge.

Then you will attach an 18 gauge wire to the terminal marked (-) on the gauge, and attach the other end of the wire with the black wire coming from the gauge light to a suitable chassis ground.

Last, attach an 18 gauge wire to the terminal marked (+) on the gauge, and attach the other end of the wire with the red wire coming from the gauge light to a 12V Switched Ignition source.

You may need some 18 gauge wire like # DW02923-1.

I have included a diagram showing the proper wiring details, as well as the installation instructions.
