Whether or not it would allow you to use it with other brands of gauges I can't say. Also if you just want gauges Speedhut also makes a line of CAN BUS gauges that will work.

Well....I installed an Autometer GPS unit for my electric speedometer, and a Painless GM/genIV tachometer driver that feeds off the crank sensor. My diagnostic port stays free this way....and will remain hooked to the Aeroforce scan gauge.
testing tomorrow!
