Thanks Bruce. This topic is very helpful to me as I had the same concern as Troy. I do not want to lose the capability of my gauges though. Do you have any recommendation for using the GM sensors to supply readings for the gauges?Bruce Bowling wrote: ↑Wed Sep 26, 2007 3:27 pmYes, a lot of the temp sensors designed for gauge use have one end grounded to the threads for contact in the engine block. This is fine for gauge work, but for EFI you will notice that the majority of the sensors have two terminals (and insulated from the case/thread) such that a separate ground can be implemented. It is for this exact reason you indicate - to eliminate the possibility of an erroneous ground path.diztroy wrote: The stock setup on my motorcycle is a one wire sensor to drive the temperature gauge. I was planing to use the stock sensor, but after reading your post I'm now having second thoughts. So from what your saying this will cause the low current sensor to be connected in a current path with high power components.
It will be somewhat difficult because the space on my motorcycle is at a premium, but would I be better off installing a 2-wire sensor that can be grounded to pin 18 the AMPSEAL?

It really would be best to go grab a GM sensor and install it, it will make life easier in the long run...
