Auxillary Fuse Block 12V Power Source

[ykf7b0]

I am looking to clean up the factory fuse block in my 69 roadrunner. I have additional circuits including electric fuel pump, nitrous solenoids, gauge lights, and electric fan to name a few that are currently piggybacked to the factory fuse block. It is indeed a tangled mess under there and the factory circuits that I have tapped into don't need the additional amp draw. I will mount the added circuit block near the factory fuse block to eliminate alot of additional lenghts of wire. I have a trunk mounted battery and I was wondering if I could get away with powering a 6 circuit auxillary fuse block from the starter relay post or should I get the 12v source from the starter solenoid, or simply run a source wire from the trunk mounted battery? The output stud on the alternator is not an option because space is a very limited. Thanks!

I ran the power from the battery now located in the trunk. Under the car to just under the drivers seat. (The cable was placed inside of 5/8" heater hose for protection). Under the drivers seat is a cut off switch I placed in a hobby type box from Radio Shack (3"x3"). After the switch I ran one power lead as normal to the starter. Than another 8 gauge lead to an aux fuse block.Before the switch (always hot) I ran a 10 gauge wire to a separate fuse block for the gps and alarm system. Things you never want turned off. There's a tremendous amount of electrical noise if you connect directly to the starter when it's being turned on and depending on how sensitive the downstream equipment is you take a chance on damaging it.
Anyway I hope this helps.
GoodLuck!

As long as you have a big enough wire from the stater to the neutral safety relay stud I'd just take it from there. You could also run the feed wire to your new block threw a relay and wire it into the ignition source so it would kill the block once the key is turned off if you wanted.

Thanks! I will go with either 8 awg or 6 awg. That's a great suggestion with the relay also!
