I've tried that dimmer switch thingy also. Worked fine for a bit, then I guess the two wires touched and blew a fuse. I replaced the fuse and made sure the two wires didnt touch, but it never worked again. (I'm bad with electrical stuff,
) Maybe I'll do it again in the Spring when I buy an EGT gauge to switch with the useless air/fuel ratio one....haha. Hey TurboDomestics, how much did you get your Autometer EGT gauge for? Kit or no? I found a Autometer Phantom EGT (to match with Phantom Boost gauge) for about $135 or somewhere around there.
