I'm about to install my gauges (FP, boost & egt) in the pillar and was wondering where ya'll have been running the hoses and wires through the firewall. Drilling new holes or running through existing rubber boots. Does anyone know where to buy rubber boots in different sizes for new holes in the firewall. Just looking for ideas. Thanks for the help

 

The dealer already had poked a good sized hole in the existing boot for my Jake Brake so I used it again... Oh well...

You will need to pull the dash cover and the headlight switch to make life easier to pull the tubes and wiring through the dash...
