rear o2s
 

whats the volts run on the rear o2s because i am going to make my own mil eliminators, what does the steada ones make them run at i guess is what i am asking

or does any one have any mills they wanna sell cheap

ebay has some you tie in for like 15 bucks my freind used those and they worked nicly.

the electrical supply is +12V. The signal should be +0.1V to +1V if it follows standards. If you look in the back of the installation manual for Autometer AF guages, they tell you what the output voltages are and what they typically equate to.

Just buy yourself a pair... They come in weather pack wrapping and are really inexpensive. making them will take more effort than the 40 bucks or so is worth.
