thanks spdbrake,

that box is a basic "ground bus" I ran all new battery cables (2 size larger than what was on the car) and I didnt want to leave any of the wiring connection to chance since we were installing an efi system, especially the ground circuits, so in addition to running a short ground cable from the battery to the frame in the back(like what was on the car originally) I ran another large size ground cable all the way to the front of the car and that box is the junction point for all its different legs... it basically grounds all the circuits inside the car for everything in the dash another leg for grounding the engine and a couple of empty spots for later if something should come up. I also used these buses under the dash as well to supply key on and constant power and ground to everything that needed to be wired under the dash ie computer. I changed the amp meter to a volt meter because I installed a 1 wire high output alternator so there were some new gauge wiring that used those buses under the dash as well. the 1 wire alternator allowed me to remove pretty much all of the old wiring that came with the car for the voltage regulator and clean up the engine bay quite a bit.. really other than the electric fan wiring in the front there are no other visible wiring in the engine compartment besides the battery cables going to the fused junction box, and that was the look I was going for. second pic is of the buses I used for power and ground and you can see the new efi computer mounted on the side, it is mounted on a hinged base so that once you are done with service or testing you can just flip it up under the dash and out of the way.
