ok im new to this...i have not messed with wideband, i know how to read it and what it is but i am just wondering if i can just power the prob itself and just use the signal wire on it and get a reading..the reason i am asking is i want to hook it to my AEROFORCE GUAGE ....can i just ground the heater ground wire, and hook the heater + wire to 12v source, and thengrab the 0-5v reading from the signal wire????
