After market gauges

Want to put “aftermarket” ELECTRIC gauges in my 66 GTO. Not sure what manufacture to use yet; maybe Auto Meter or Sunpro. Any suggestions is appreciated....My question is; can I use the engine harness ? That is, using the temp sending wire from the engine harness to run the aftermarket temp electric gauge; instead of wiring it with a new wire…. Same thing with the oil sending unit wire. Hope this makes sense...

I have been looking at Dakota Digital.
They have a kit for our cars, and provide any adapter to sensors based on your needs, it is improtant to me since I am doing an LS swap. They are worth calling.

Gauges

New Vintage USA:
I like the 1967 series and they can custom make any face you like and install led lights in the gauges.

The sky drive system is a great idea and I like the G/Stock series

Thanks for the new info..I really like the New Vintage series 67 gauges....I think that's the one! Now as for my question stated above.....can I use the excisting engine harness, without having to run a new wire....I think if I just tap into it on the other side of the firewall ( inside the car) , it would work.......what do you think?

My 69 GTO uses a printed dash ciruit. A previous owner installed some aftermarket and had to run new wiring. I'm not familiar with the 66 GTO, I don't think you have a printed dash ciruit. So, you should not have to rewire the gauges. I'm not sure, I'm just guessing since you don't have a printed dash circuit.

You can indeed use the wiring that's in place on your '66. You may need to make up connectors for the gauge end of the circuit. I take it you have lights right now, and not a rally cluster? If so, you'll need different sending units for the oil and temp.

thanks guys for your input. This new tri power I bought from Mike's Tripowers will look much better with one electrical wire running over the intake/head area than the mechanical tube line. Welcome - Pontiac Tripower.com - Your One Stop Tripower Shop
So far I'm real happy with his workmanship and attention to detail..... I will post more after the install.........If anyone out there has done a changeover to a tri power, I'd appreciate any advice you may have......overlooked parts I may need etc.....

It is best to have lights and gauges. The light will get your attention to monitor the gauge if something goes wrong.

How would you wire both? Do I need two different sending units for each, the temp and the oil? Can I run them through the same harness wire? thanks for your input......

you need to use two sending units for the water temp. On the oil use a metal ussually copper line on a 1/8" pipe T with a idiot light sending unit on the other end or connect to two locations. no big deal. no one sits and just looks at there gauge. a bright red light gets your attention.
