i will move the battery when i make the trep a project car. that way i can do a single ram air intake to each throttle body. anyway, probably the best bet to run wires throught the firewall is to either take the grommet where the hood release goes thru or else drill a small one. if you have the tool, drilling a custom-size one is almost better because then you can put it exactly where you want plus you don't have to worry about putting undue pressure on a fairly important wire. you wouldn't want your hood flying up on the freeway or anything is what i mean. just remember if you drill you want to throw the wire thru, then put some caulk in the hole so she doesn't leak water or air.
