What are Y'all using as a main power junction up front when the battery is in trunk? I'm planning on running O gauge cable to one and then send wires to starter, alternator from there looking for suggestions/pics of what you have used for this junction.

well maybe I'm not clear those are for going through the firewall - for that I'm going to use a HD grommet, what I'm looking for a a junction where I can connect several leads for starter, alternator fans like a buss bar of sorts
similar to this but with protective cover http://www.remybattery.com/media/catalog/product/cache/1/image/9df78eab33525d08d6e5fb8d27136e95/t/e/terminal-bus-bar-4-point-positive.jpg

I'm looking at running this one.

for my setup I'm running a 1/0 gauge wire direct from the battery to the starter with the solenoid in the trunk. So it won't go near this terminal.
Then I'll be running a fused(or 80A circuit breaker) 8 gauge wire from the battery to one bolt on this terminal and either an 8 or 4 gauge from the other terminal bolt to the alternator. allowing a bunch of other fused power wires to be connected in-between.
And even though no-one will see it, my OCD will sleep good at night.

I'm using one exactly like the one in the ebay link below.

Has a battery jumper post, plus multiple + connections, and a cover too.

I’m using the one in my third link. I’m simple minded so I try to keep things simple... :D
That combined with the bulkhead pass through in the first link gives me everything I need. Let’s me keep my Vintage Air connections inside the car.

I mounted a power distribution block, see first link, on the firewall near the master cylinder.

I also added a power relay module nnear the the driver driver sidee radiator support that provided two fused 60A circuits, one for battery power and another for ignition power. I used to power the fans, A.C. relay, headlight relays, fuseblock, etc., etc.

I went to West Marine and bought something like this for my grounds and positives for fans at the front on the engine bay. I then ran 2 10g wires to feed it. Only issue is its not covered for the positives but haven't had any issues.
