Where is all the wiring & How do I make my engine bay look like this?

I am also planing to mount the coil underdash utilizing a bulkhead connecter through firewall.

Will also constuct a flip down panel hinged at the rear underdash to mount the MSD,fuse panel and associated relays. Out of sight, out of the way.
Trunk mouted battery as well.

I too have removed all enviroment elements so there is plenty of room.
Still have to figure out some sort of defroster though. But thats for another day.

Yep I was thinking about doing the same thing on my aspen, Summit sells a nice through connector for the coil so you don't take a chance with rubbing wires.
