I'm planning on using the 2" hole in the firewall that is to the left of the brake for my Edge EAS sensor wire. Does anyone know where to get a grommet or plug that would fit that? Or does everyone just leave it open?

 

Harbor Freight has a section of one of their aisles that has a decent selection of plugs and grommets, sold individually or in multi-size kits.

 

Many trucks have a few " pass thru" wires already in place. Check the harness behind the master cylinder for taped back wires that aren't connected, pick a size/color and you should find the other end under the dash near the parking brake pedal mount.

 

I'll have to check out HF, good to know. I don't have one near so maybe I'll call.

I found those wires, but I need to actually pass through the cable for the Insight so that won't work.

Any aircraft maintenance supply or pilot supply
should also have a good amount to pick from.
Or give this guys a call
Pilot Supplies, Avionics, and Homebuilt Aircraft Parts from Aircraft Spruce and Specialty Co.

I don't know why I didn't think of McMaster, they have one for $15.27. Thinking about it, do they make any with a membrane in the middle? More a rubber plug I guess? Then I could slit it and it would still kinda seal around the wire? Maybe I'm just overthining all this... I just want to do it once and be done, don't like having to do things multiple times and waste money.

 

Hmm, I'll keep searching but I found something promising:
Grommets DG, PG membrane - AVT Industrial Components
Just need to find someone that sells it, LOL.
