I just order gauges the other night and was wondering if I could wire it up with my egde egt gauge? If the new gauge has eyelets like the edge connections have could I just put the eyelets together to the respective spots and have both gauges work correctly? I was just going to do only the gauge coming but ni like having the alerts on my edge and also want to use a gauge on the pillar without drillling another hole and having two probes in one exhaust manifold or drilling and other holes for that matter.

 

I was wondering the same thing about trans temp gauge. The best advice I got was;
Connect the original gauge, and see what its sensor reads. Then attach the other harness to that gauge and see what the gauge does. If it jumps one way or another, an accurate reading will not be available.
Its worth a shot, I doubt anything will get damaged in the process.

 

then again it would be kinda neat to know what #1 and #6 are running.... or put one right next to the turbo and one by #6... just saying... i understand not wanting 2 probes though too..
