Firewall pass through
 

Just wanted to post this up. I was looking for a cleaner way to pass my harness through my firewall. I contact the owner of the business and showed him a design and he was able to produce it. Hopefully this helps others. I am not affiliated with the business or owner .

You freaking rock.

You are the man

I can't tell you how happy I am right now

I will be ordering two of these in the morning.

Thank you!! I use to be heavy into the import scene and a company made these for Honda harnesses but not domestic cars. I contacted the owner of Sharpe performance and told him the potential market for a clean quality pass through and sent him the design you see and literally in a couple a days he had one prototype made.

I contacted motion race works to make them initially and never got an email back.

I was honestly trying to help a USA company expand their product line.

I'm just glad it helped others. I have a few other simple ideas that I'd like to bring to market to.

How does this mount to the firewall?

It's funny as I was talking with the guys at Kwik Wire last week at Good-Guys Columbus and showed them the motion racing firewall grommet and they agreed there needs to be something like this.

Rad Rides has a machined plate that they use on their build with the Circular Connectors. Which is very cool but ''pinning'' each wire would not be fun.

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!

I hope these images help
