NO juice update, any suggestions?

Ok I just shot the wires. I have continuity from the battery, in and out of the kill switch, and also both in and out of the starter. Then out of the starter the large wire goes to a little silver box on the inner fender well. (relay switch)? That little box has 4 posts. The large post to the rear has the starter wire hooked to it, middle post has a small ground wire, and the 2 small posts to the front (one is above the other) is the PROBLEM! I have continuity at the large post that comes from the starter but NOT to the front 2 wires. Bottom wire is yellow smaller diameter about 18ga and the top one is brown and yellow wire about 14ga. They both go to the black box on the firewall one goes to the 1st series from drivers side 2nd down from top. The other goes to the 2nd row from drivers side 2nd down from top. Another words they are side by side.
I'll continue in a sec
