Temperature Gauge Wiring Diagram

I recently bought a 1967 Mustang Coupe 289 2V. The guy I bought it from had an external temp gauge mounted below the dash. I want to just use the one in the instrument cluster. I disconnected his gauge and put a new temp sensor in the intake manifold and new engine wire harness from the sensor to the firewall but the temp gauge isn't working. I am looking for a wire diagram that shows the wires from the firewall to the plug that hooks up to the intrument cluster. Let me know if anyone can help.

i have a factory electrical assembly manual for the 67 that details EVERYTHING...it's what the factory line workers used when they assembled the cars. Next time i'm at the shop I can grab it and scan the relevant pages for you if you don't have it fixed yet.

Here are the diagrams

Congrats on your new 67, a great year for Mustangs

You can find the wiring diagrams on this website

Also, I want to say, you may want to keep that other temp gauge connected. The original temp gauge has some problems with accuracy and it may lead you to think that your car is running hot. You can find many posts about such problems on this forum.

Take care
