Ah little things. when you don't have a wire gutter or wire tray you need one. Used existing holes in firewall. Still need to fill in the missing wedges so its all one piece. The idea is the main engine compartment bundle will come out of the grommet, secured to wire tray and down passenger side. The headlight portion of the harnes will run along the drivers side. Ive got something special in mind for the air cleaner ;).
