I was wondering the same thing on a gen IV...
Thanks Mark! Now if I could only know what is a brake booster and a grommet and better yet where to look for it ?To the right of the brake booster is a grommet. You cannot see it from inside, but if you push a wire through you will find it on the inside.
The brake booster is the large round cylinder on the firewall, drivers side engine bay. To the right of it is an oval rubber "grommet" (kind of under the plastic cowl area) that will lead you into the cabin above the pedals.
Hope that helps.
Whatcha wiring to the front? Laser detector?
