Hey all, not sure if this should be posted in this section, but I have a couple questions I need help on, first question is, i dont have the auto dim rear view mirror and wanted to know if i bought one that has it, can i just swap it, or will i need to have it programmed? Second question is, I have a Alta boost gauge that worked for about a year, then it started to give out on me, the needle still goes up and down from starting the car, but doesnt move anymore, it used to flicker and move once in awhile but now doesnt, I checked all hoses and connection and they seem fine, should I bought all the wiring kit again? Or should i check somewhere?

Mirror info on how to replace it and what needs to be done can be found in the Modification section. There are a number of threads there.

Sounds like the gauge is shot. Probably just need a new gauge not all the wiring. But check with Alta, I bet they can tell you how best to test it.
