I Keep popping 15 amp fuse
 
I Keep popping 15 amp fuse on my wire coming off back of alternator going to my "hot" power block

Does my wiring seem correct, it is based off research i did on this site and other forums.

Battery has 2 wires - 2ga to post of starter - neg to frame

Starter has 3 wires -2ga from + batt
- 10ga from big post to back of alternator
- purple wire from factory harness to little post

Alternator has 3 wire - 1 wire in plug that goes into computer
- 10ga coming from large post on starter
- 10ga with 15amp fuse going to constant "hot" power block


Harness only had 3 relays Fans, Fuel pump, IGN. (no other fuses)

- 2 wires coming off relays that called for "key hot"
- 5 wires coming out of harness and relays that called for "12V hot"
- 3 ground wires
- relay ground wire

Headlights/gauges are running off the stock harness/fuse box

Truck is running very rough and will barley idle. Seems to be misfiring

The hot box is running the relays for the fans, fuel pump and ignition. Along with power to the PCM and obd2 port.
