so I've got a distribution block I'm using for my hot wires for tach, fuel pump, roll control, afr gauge and voltage gauge. The other half of the distribution block will be for gauge lights. I will run 1 wire from the block to fuse box for each. Do I need to run a jumper wire from one set block to another to make my hot wires work independently from the lights and lights independently from the hot wires?

this is the block I got.

Can you rephrase your question?

from the distance, what you got is a rule full of individual "junction points". You could make any setup with that, but if you want to "split it up" into two "buss bars" will need to make a cascade of jumper wires for each section from the source you want to make

just like this:

there is another kind of distribution blocks where the attaching points are linked between them with the base plate where all the screws are attached... on this pic is being used to source neg and pos, but could be used for two diff positive sources, one each side. This would save the use of jumper wires cascade

another kind you could use are 2 of these ( one for each source you want to split out ), where a major stud is used for the input signal ( whichever is ) and the screws to attach whatever you want to source. Everything on the same bar plate

sometimes the ammount of wires you need to get into the buss bar is not that huge, and use just a single juntion point for everthing could be quite enough:

just found this distribution block with the jumper system ( same idea of the reply#5 )

and this, where each side will spread the signal you want to split out

I have used the types that Nacho showed in posts #4, 7, 9. Depends on mounting location and parts availability.
 
Thank you guys. Do I need to run a inline fuse between the block and fuse box?

I’d consider that of course, depending on the expected load on each block section

althought dash ilumination got its own fuse already on fuse box. You could change the fuse with a couple of amps more if adding 3 or 4 extra gauges.

I have 2 different types, the big one is for my large loads, amps & fuel pump, I think its rated 80 or 100amps, its mounted to my battery box with a circuit breaker protecting it.
The smaller one is in my engine compartment for my fans & MSD box.
They are all fused circuits.

Even simple terminal blocks have max amp values so do your homework.
I prefer screw terminal connections with star washers on terminal and fuse blocks. Push-on connectors tend to spread and loosen. If you must use push-on style, use the plated steel, "high temp" ones. Never the cheap aluminum ones most commonly found in parts stores.
