You drill a 2" hole in your firewall, 2 holes for the mounting screws. Mount the firewall pass through on the engine side around the harness, have a buddy tighten the the nuts on the inside of the car and your done.

Ohh so its just the 2 bolts, no sandwich plate on the backside to keep help pull the firewall flat if its not on a perfectly flat spot. The thinner passthroughs have more bolts and conform to the firewall, my concern is the 2 bolts may not suck it perfectly tight to the firewall. That would be remedied with a 1/8" backing ring with the 2 bolts. I can easily fab that up. I'll consider picking one of these up. Thank you!

There's also an ebay seller that sells one for a smaller diameter harness(for Hondas) that I'm going to be using on my main vehicle harness. The item is listed under "k tuned firewall grommet" . I would post a link but I hate posting up links then they expire.

Got mine the other day and it will be mocked up this weekend and then off to get Anodized black.

These are very cool. I see on his website there's an option for hidden or visible fasteners, which one do you have there? I was looking on his site but see no way to contact him to ask. I'd like to see a version of both of I could.

Thanks!

So the pictures I posted are the hidden hardware version as you have to tighten the nuts from inside the car.

And the version that Ahmad B posted is the version with the bolts inside the engine bay.
