Fuse/Relay Box for accessories

I have been looking, scheming and reading about fuse relay boxes to run accessories. After looking at some of the real nice stuff out there I decided to go with the inexpensive way and use the power distribution panel out of a Cherokee at a junk yard. I only paid $10 for it and it came complete with fuses and relays. I went to Radio Shack and dropped $6 on two terminal strips and then to Home Depot for 10' for 18/7 and 10' of 18/5 thermostat wire. All in all I spent around $25 for everything.
I got 9 relay/fuse pairs and 5 fused terminals using all the available slots. I decided I would make all relays activated by supplying +12v and just cut and soldered wires. The terminal strips I mounted on the outside of the box for easy access to add accessories and I will use the thermostat wire to run to the switch panel in the cab. (as yet to be fabbed). These wires along with a 10 amp 12v lead to supply the switches makes for a nice neat singl entry point through the firewall. It also give me 3 extra wires running from the cab to the engine bay future use. All this will be wrapped in loom and hidden. The bow I will make a swing away mount above the battery to keep it high and dry but still give me access if needed. All in all it was a very inexpensive way to add circuits and I doubt I will ever use all 9 relay fuse pairs but they are there if needed!

Do or do not. There is no try.

Thank you, I didn't go into more detail only for the fact if had to explain more then the reader probably shouldn't be doing this. However, it only took me a few hours and really just knowledge of how relays work and how to solder. To add an accessory I just have to hook the +12 from the switch to "Sx" terminal and the power to the accessory to the matching "Px". The ground for the accessory will be whatever frame ground is local. Or if I need just a fused circuit one of the "Fx" terminals
