UPFITTER switchs in my 2003 - PROBLEMS

Hey guys,

Today i decided to tackle installing the 05+ upfitter switch kit into my 2003.

Mounted the relay box - no problem
Run wire loom across dash - SIMPLE!!
Plug into back side of CJB (Central Junction Box) - CHECK!

at this point, with the key in the 'Run' position the switches light up when turned on, and the relay's click when the switch is flipped on and off

HOWEVER, there is NO POWER coming to the blunt cut wire for any of the circuits.

It seems to me that there is probably a fuse somewhere for each of the following:

AUX1 - 30 amp
AUX2 - 30 amp
AUX3 - 10 amp
AUX4 - 15 amp

However, since i have a 2003, my fuse panel doesnt have places for these... where are they located in your 05+ trucks ???

a scan of the fuse/relay pages from your 05+ owners manual would be sweet!!

Also, another issue i think might be a problem, is that in my 03, the relay in the main panel thats for the upfitters in the 05's is for the trailer battery charging circuit in mine...

Has anyone here done this before ? what'd you do ?

ALSO;

I was going over the electrical schematic for the upfitter circuits in the 05's, and it looks like the fuses for the 2 30-amp switches are in a place called the "Battery Junction Box" and the other two are in a place called the "Smart Junction Box"

Anyone have any idea where these junction boxes are?

I hope you are able to figure this out. I am wanting to do the same thing on my 03 also.
