Bus Bar in Fuse Box: Good for Constant 12V Power?

[DINOZR]

I’m running a wire (6 AWG, inline 40A fuse) to the battery, and I’m wondering, can I connect to the bus bar on the side of the fuse box (outlined in red below)? This bus is connected directly to the battery with a short, thick cable. Am I gonna mess up any sensitive computer ******** if I do this instead of literally going to the battery + terminal?

Reason is that I can make the install look super clean if I go this route.

It shouldn’t be different than a direct connection

Make sure to find out what that busbar’s amp rating is. Also determine how close the bus bar is to it’s max with what’s connected to it now.

I can’t imagine FOMOCO using a bus bar that has a higher rating than what loads they have planned for that bus bar to handle. I mean look at the thin gauge of the AUX wires.

This has “voided warranty” written all over it.

Those are fused, and the fuses are rated for the load that the circuit is designed for. If you connect your equipment there you risk overloading the BJB or blowing the fuse.

Didn't realize this. I traced the connection of the first bus terminal back to the positive terminal and didn't find a fuse on that cable, but I must have missed it. I'll just go straight to the positive terminal. Thanks for the feedback.

Looking at the non raptor BJB, The spot that shows to be empty on your PDF shows to be for glow plug control module (Fuse 110) 125 AMP. Just pointing out what i see and in no way am i saying this is what it is... But worth a look.

I believe the 1st lug is connected directly to the battery and supplies power to the BJB.

Valid point. If you connect to C1035A, that is unfused battery power to the BJB. Just be sure the connection is clean and tight; that's a high current connection point.

That's good information. Thanks. Though my "empty" label means that there is literally no metal in the socket to take a voltage reading from with my multimeter. So it's not just "unused," it is no-shit "EMPTY."

Ha! I haven’t looked so I assumed it may have been populated but no lug.
