I did the purple wire coming off the trim button and tapped into my new bilge pump direct ground wire, and Presto,
calibrated it, installed the sensor in my tapped exhaust manifold,

I hooked up the hose and presto it is reading about 11.5 at idle and when I rev it it jumps to about 13.5.
I am going to put it in tomorrow and run it to see where the afrs are at,
I have not installed the RRFPR yet, but I wanted to see where everything is at.

thanks for everyones help,
