Hey Fred. Check my build thread. I have removed all wires and relays on passenger side except the wiper motor wires.
I kept my charcoal canister to help with gas fumes. I relocated it to the firewall so that it's hidden. It's not necessary to keep but have heard that it's possible to smell gas fumes without it.
Driver Side:
Routed wires through body directly to the left of where it goes through the firewall. (See pic)
I only had to extend the wiper bottle and brake level plugs. Everything else is all factory length.
The hood release cable I routed through a hole the was already there. (See pic)
