so I am installing my gauges today and I have almost everything done. but I started the truck up and the fan cut the EGT wires. Can I use just regular wire or does it have to be a certain length or certain type? these are auto meter gauges. thanks guys, keep those fan belts clear.

 

I hate being the bearer of bad news but thermocouple wire is special. The type "K" thermocouple that is used with your pyro is made from Chromel & Alumel - if you want ANY type of accuracy you'll likely have to order a new thermocouple cable. As the tip of the thermocouple is heated, it produces a very small signal [millivolt (or thousandths of a volt) range]. If you even solder or splice the wire, it will cause measurement errors due to resistance and temperature differences at the splice.

 

thats exactly what I was thinking was going to happen. but I just had to confirm it. no biggie. do you think I can call auto meter and just get another or will I have to order the thermocoupler and all? thanks alot Il button her up until I can order. thanks again

 

If you cut it after the connection between the thermocouple and the harness, I don't see any reason that you couldn't just get a new harness and leave the thermocouple in place.

 

It was my understanding that the harness wires also had to be certin gauge and length. I think my DiPricol's said not to modifiy harness length because I guess they take into account current lose due to distance and resistance.

Theres no reason why you shouldnt be able just to get the cable - they should prolly just give it to ya if you bought a complete set of guages. Good Luck.

 

This is not an emergency. Moving to performance.
