i want to go to isspro gauges but i have auto meter sittin on my dash right now. i was wondering if the thermo coupler and red and yellow wires would work from the autometter to the isspro. i need to get a new boost gauge since i broke it...... some how i blew a seal up inside the gauge and i want isspro gauges since i think the look better and hopefully profrom better. thanks guys

 

Yep it is the same thermo coupler

 

how can you tell if the gauge is bad or if its the thermocoupler? can i unhook it and read some kind of ac or dc voltage while the motor is running. one rig is doing the intermittent thing and the other never has worked.

 

well i was talking about the cheapy boost vacume gauge i have. i was able to get condinsation in the gauge wen i peg the neddle past 30
