Wiring up new gauges and other accessories

[69dodge383]

So here is the deal. I have some new items I am going to be wiring into my car, but I am not 100% sure I am going about this the right way. So here is what I have and what I am planning to do.

New items to hook up
1. Summit digital tach with shift light
2. Autometer A/F gauge driver side
3. Autometer A/F gauge passenger side
4. Summit digital oil pressure gauge
5. Summit digital water temp gauge
6. Summit digital volt gauge
7. Oxygen sensor driver side
8. Oxygen sensor passenger side
9. Electric choke
10. Exhaust cut out switch
11. Electric fuel pump
12. Fuel level gauge
13. MSD box

So I am adding quite a bit. I have the relay and the wiring installed for the fuel pump already but am unsure if my approach for the rest of the items will work.

I bought the items below from summit and for the 12v wires was going to run a wire from my 12v source to the junction block (link below) and connect everything to the junction block (link below), I was going to do the same for the ground. My 12v hot is coming from the one side of the ballast resister (i have connected both sides of the resistor with a common wire.)

So now I am wondering am I going to have a fuse issue with the way I am going to do this? I know I am putting a lot of items in.
