I am getting ready to hook up my boost and AEM AFR gauge. They are going to be mounted in the Autometer A-Pillar. For those who have done this, where did you bring the wiring/vac line through the firewall? Also what power source did you tap into? Any help and/or pics would be greatly appreciated.

 

I brought my wideband harness and my 4 gauge amp wire through the firewall with the rest of the factory harness right behind the battery. You have to take it out to access, but no drilling is required.

 

So after coming in the passenger footwell, how did you route the cable to the drivers A-Pillar?

 

I only ran mine to the center console, but just snaked it up and around the various brackets.
