These Firewall Passthrough grommets were designed for use with the Megasquirt Goldbox wiring harness but can be used for any ecu wiring you need! The inside diameter measures out to 22 mm or 0.85 inches and helps to securely hold your wiring in place as well as act as a weather barrier to keep any water from your engine bay from entering your cabin.
The passthrough is made out of a flexible material to help relieve any strain on your wiring, as well as improve the ease of installation into the firewall itself.
View our Megasquirt install video here for an idea of how the grommet is installed.
