I want to do this right now why i have the time... What is the BEST wire to use under the hood for the 12v switched power wire for the 4 wire 02 sensor? thanks..

just a shot in the dark but maybe try the power wire that comes out of the asd relay it looks pretty big

[SpoolinGLH]

hmm any other ideas..what wire is everyone using when converting to 4 wire?

thanks lol but i mean what switched power wire.... i know im making this harder then it is....just trying to see what is easier

There should be a dark blue 14ga wire that that branches off and feeds the solenoid bank, diagnostic port and other things on the passenger fender. That is a switched source. There may also be an unused connector on that circuit over there; which is what Shelby used on the GLHS' to power the O2 sensor heater.

FWIW, the 88 up 4 wire is fed from this source. Just be sure you run a separate ground from the sensor heater.

Thats exactly the answer i was looking for guys. Thanks. What shelby did on the glhs is good enough for me lol.....
