Cluster wiring

[biohazardbill]

This might should go in the electrical section however it is specific to these trucks so figured I would ask here. I have a 67 pickup that had a no guage cluster. I have since added gauges to this and now it is time to wire.

The new temp and oil gauges are electric, my question is can I use the factory wires that used to go to the dummy lights as the wires that now would be sending the signal? Ie can i take the wire from the old sensor, hook it to the new sensor then under the dash run that wire to the new gauge.

It may be a smiple question, just did not not know if the wires were of a resistance type like the coil wire where you have to change it out to power hei ignitions.

Thanks in advance.
