Most of the AC stuff is pulled out of my car. So im going to pull the rest of it out tonight. The box under the dash is all thats left. What I want to know is where can I get ahold of a rubber plug for the hole thats left in the firewall when I pull that box out. I want a rubber one cus I want to cut a hole in the rubber plug and run my bat cable since im running my bat to the back also.

 

get the plug from an eg civic. and run the battery cable thru the existing hole thats hiding inside the passenger side inner fender liner.
