How many of you who installed a gauge or set of gauges went through the factory firewall grommet? I'm entertaining the idea of doing the evomoto 2nd firewall hole mod... comments? Is it necessary?

I'll be running 3 gauge wires through there to my control link...

 

There is a decent hole on the passenger side.. you could make it bigger but it might be a PITA to get a drill in there. I just like the fact that is away from everything. I have a pic if you're not sure what I'm talking about.

It should be more than enough room depending on how many/thick the wires are.

 

hmm, I dont know what hole you are refering to without seeing it...but I went thru the grommet on the FAR right side of the passenger firewall. The one that is practically impossible to get to from either side...I have a pic you you want.

Good find, I couldn't find it myself -- I may be dumb today

Thanks for the info guys, I decided not to run the wiring today but I did get my CH panel + gauges in the car and the radio relocated.

I will likely follow the evomoto write-up on creating your own firewall hole since I need to run 4awg through there next week for the amp install.
