I Need Help Wiring an Aftermarket Temperature Gauge in a 1967 Ford Mustang

Quick question. My original 1967 water temp gauge is not working. I was thinking about buying an after market sunpro temp gauge. Would I be able to just run the sending unit to the gauge and have it work? Or do I need to power it from the battery. Just wondering because thhe. Wires are all wrapped and a mess .and I could easly run a single wire from the sender to the gauge.. thanks!!!

you need to use the sender designed for the aftermarket gauage and it need a power wire run to the gauage.

A sending unit should come with the gauge, use it and not the original one for your stock dash gauge they may be set different. You'll need to drain some coolant before removing the original sending unit, enough to get it below the intake level. Pulling the top rad. hose off may drain enough, be sure to catch it all though.

It looks like you'll need to tap into a + source for the gauge from your ign. on or accessory wiring for the Sunpro gauge. Here's some Sunpro instructions from their website.


'67 Coupe 289 stroked to 333, AOD, 9" w/3.50:1, PDB, Candyapple red w/red deluxe int., PS, ext. decor group, light group, foxbody seats.

Since you have already tackled this problem with your temperature sending unit, I have a similar problem except that the wire to the sending unit under the hood is missing and I need to know where the original wire originated from. I know that the color of the wires at the gauge but I can't find that same color wire under the hood. You help would be greatly appreciated.. jim
