Just like the title says. I am installing an electric cutout with my Borla catback and wanted to check what the best routing for the wiring would be.
I dont know if it would be better to route it thru the spare tire well into the cabin to the center console or if to do it under the car.
Would also appreciate suggestions as to where to mount the switch.

 

Well, I did it the following way:
Between trunk floor and muffler heatshield to the driver's side, over axle and the panhard bar, zip tied it to the brake & fuel lines all the way up to the shifter.
Then I drilled a 1/2" hole on the floor next to the shifter opening (M6 car).
Ran the wire thru a grommet to the CD storage compartment in the center console.

 

Well I went through the spare tire well into the car, along the pass side door sill, under teh pass seat below the carpet into the center console and mounted the switch in the ashtray.

 

Stock grommet under passenger back seat, under carpet, cut a slit in carpet under console, ran it under the console, back behind the 93-96 console "cd holder" or whatever, and mounted my switch below the cig. lighter.
