I have a 19 tundra crewmax, where have you run wires through the firewall to run off-road lights and switches?

Assuming wires are going near driver, there is a big grommet through the firewall under the ABS module that comes in near the parking brake. Be careful not to damage existing wires making your hole.

The harness comes where you can disconnect the main harness about 2-3 feet from the switch, that connection is about 3/8-1/2 inches wide. And yes it will on the drivers side, not sure where I’m putting the switch.

On my 08,I took a coat hanger taped the wires to it and went through the grommet where the parking brake went through. The hole for this harness connector will have to be larger.
