Ok I have a six gun pda system and I also got a couple gauges for the cab. The six gun system came with an EGT probe. Would I be able to run my EGT gauge off of the same probe or will I have to drill and tap twice. (Note* I will be playing it safe and be removing the exhaust manifold to make sure no shavings find the turbo.)

no answers?:rolleyes:

yes you can run it off the same probe

Banks sells a EGT gauge that will work off of the six gun module. I have heard of people running two things off of the same probe, but I don't recommend it. If you don't have a Banks gauge think of it as an opportunity to buy the BD manifiold with the probe hole in it for one and tap the passanger side manifold as usual. ;)

how?

why is it a bad idea?

They read on resistance and with 2 gages it may throw both readings off!

so it looks like my best bet will be to drill and tap twice.

Thermocouples are not resistance-based sensors. They output a very small (millivolt) DC voltage. As long as the displays have a high enough input impedance, you can connect two or more readouts to a single thermocouple by simply connecting the readouts in parallel to the thermocouple. To check whether the displays are loading down the thermocouple signal, just connect one display to the thermocouple and make note of the temperature reading. Then connect the second display in parallel to the first. If the temperature reading on the first display stays the same, you are good to go.
