Installing junction box for battery needed connections
I recently rebuild the engine harness in my 1987 Chevrolet V30. My goal is only have one wire running to each terminal on the battery, however with the newer accessories (H4 upgraded headlight harness, HD power window kit upgrade, etc.) I am finding this may be a challenge because all of these accessories are required to draw power from the battery.
I was going to install a Stud Type Plastic Junction Box in the engine compartment to run all these connections there. Is this how people are handling these type of situations? Any tips or recommendations - I am all ears. Thanks everyone. |

That's what I did. I mounted a 4 lug distribution block on the core support by the headlight bucket. I still ended up useing batt terminal extenders. I am running electric fan relays, headlight relays, Vintage Air A/C relays and LED light bar relays, which of course, say they need direct battery power. And when I add the Amp for the stereo, there will be another batt connection.

I'm curious what hardware you guys used/are going to use. I've got this in my cart at Summit. Was also thinking of using a single stud type distribution point. Thanks, -klb |

I have one of these under the hood in my 70. Each circuit gets it's own fuse. Nice and clean. I want to do a second one in the cab for accessories.

Noticed my electrical system responded quite well. I must have gained 50 hp and 2 seconds in my 1/4 mile ET.:metal: |

Currently connected to my fuse block: low beam relay: 2x 35 watt = ~6 amps => 10 amp fuse High beam relay: 2x 55watt = ~9 amps => 20 amp fuse Fog Light relay: 2x 55watt = ~9 amps => 20 amp fuse Factory in cab fuse block: 30 amps. Kind of a guess. Biggest fuse in the fuse block is 20A. I should probably see how much I actually draw with the HVAC fan and wipers on. Ammeter: 5A - That's what was there before. |

I'm using this "industrial" piece. I like the quality over typical automotive types. I have a short 4 guage jumper from the battery to the large primary hole. Then I have 6 outlets to run my accessories. It is a clean, durable piece and I prefer the setscrew locking feature. Keep in mind you must use in-line fuses on all the outlet circuits.
