Run the power wire under the car and drill a hole in the back. Some convoluted tubing and through the frame rail is how I did mine.

Unless you got something else planned.

Last kid that tried to drill through the firewall ended up having to buy a new brake booster. Goofball drilled right through it. Years back though.

There really isn't a decent hole in the firewall and water is always an issue, in the back it's not as big of a deal and you can see both sides to RTV shut if need be or use a proper grommet.


Just please don't zip-tie to a fuel or brake line, big no no there.

If you have an automatic there is a hole where the clutch would be. It's just covered by a rubber piece. If you take that out you can easily drill through the plastic and it comes out to a very open spot underneath the fuse box. Good access there. I used it for my N2O install. Here's a really close up shot.

Just get an air-powered drill and some diamond tipped, titanium-bodied drill bits and get it going! hahaha.

No, but really, I think that there is a couple pilot holes on the right side of the firewall..... if I'm not mistaken...... because I think ford used the same print-out for the front clip for LHD and RHD..... but I might be wrong.... so if I am, just ignore me.

don't think you would want to drill on the right hand side because if you have a leek, thats where the computers are at...
