Question about wiring for a chevy blazer

[00stang49660 10+ year member]

I have a 1995 Blazer. I am hooking up my sub and amp but im not sure where to run the power wire through the fire wall. The battery is on the passenger side and i don't see any openings. Where do i run it through? Do i have to drill into the fire wall to run it? Does anyone have pics of their blazer where they ran theirs?

Thanks

Hey shawn!

If you see no grommets that you can tap into then you gotta drill through the firewall...FUNNNN

Be careful! post pics

look in the passenger floor board, there should be a drain plug there, I know my 98 had it. Just knock drill through it...

Yah, Easiest way is to drill through the firewall, Just Verify where your drilling before you do, Like look under the hood at the firewall, see where you wanna drill, then go in the car, and see if you guesstimate where the spot was under the hood, so you know your not gonna drill into anything important

Just make sure you cover where the cable is comming through the hole with some electrical tape, because eventually the metal is gonna cut through the cable

if you look kinda behind the exhaust manifold there should be a spot in that general area where the antenna or something goes through with a grommet. if you do end up having to drill you'll need something other than electrical tape like supposed MECP certified guy said. you can get a rubber grommet or that door edge stuff. it's a bit of a pain but you'll want to cover the sharp edges as they will rub through electrical tape quite fast if it's rubbing. therefore electrical tape won't do any good except may an extra few days at most before it starts on the wire jacket.
