BlueSea Systems Safety Hub 150

I'm an electrical newbie, I generally prefer NOT to do much more than the stereo components, but I'm copying some of the stuff @RainMan_PNW has done on his 21 TRD Pro, namely the Rago Fabrication compressor mount as electrical distribution and a BlueSea Systems Safety Hub 150.

From what I can gather, I need a relay so the stuff I connect to the SH150 is only usable when Ignition is on, which is what I would like to do since I plan on installing seat heaters, running the DD 42" light bar from it, and eventually an amplifier when I replace the stock speakers/amp in my 2019 TRD Pro.

There doesn't seem to be any downloadable instructions on BlueSea Systems website, and an email to their support has been unanswered for a week+ now.

Here's the wiring diagrams as listed on their site for the SH150. How would I go about putting a relay in the right side config that ties to ignition? What kind of relay, or is that a dumb question?

 

That distribution panel supports some high current. Are you sure you're asking for a single relay to sit in front of it? A quick look at McMaster is showing 50A max. Generally, you'd put in a DC breaker before the panel and then install a relay for each sub-circuit after the panel (identical to a house). I would trigger the heater and light relays with a switch/push-button and the amp relay with ignition.

 

Your relay(s) would come after the MIDI fuse on the SH150 to turn on your different accessories. The SH is essentially acting as a fuse block to protect the power feed to the accessory (I have the SH 100 as I didn't need the (-) bus bar feature). You would fuse the ignition feed going to the relay as the trigger as well. Your circuit is now protected. Hope that makes sense

Further breakdown (just how I would do it)

DD light bar: your relay would come after the safety hub. You would have a fused lead coming from ignition that goes through a switch and to a relay placed after the SH MIDI fuse. Now your light bar will only operate when ignition is on and you activate the switch (dont want the light bar coming on every time your ignition is on)

Amp: You have a lead going from the SH MIDI fuse directly to the amp. Majority of amps have a remote turn on feature that receives signal from the head unit once the head unit turns on

Seat heaters: same as DD light bar above

Hope this helps

 

Thanks.

The DD light bar came with a harness, relay, etc. and it is wired as per the directions from the CaliRaised LED lightbar switch instruction video, but will be re-wiring it when I take the dash apart again for relocating the Tow/Haul and Window up/down switches, and the blackout rings so it is ignition protected, and tied to illumination.

On a side note, I really hate having to watch videos for stuff, I would rather have a PDF I can reference, or print. That will likely be a factor in choosing accessories in the future. Did I just date/age myself?

 

haha no, not at all. I prefer paper as well

 

I need a stiff drink, a night without honey-dos, and an hour to sit and think through a sketch here.

as others have said, the power capacity for the SH150 is much higher than a relay can handle - think of it like a sub-panel, not a switched device. Your individual loads can be made to only work if the ignition is on by using an ignition circuit to run the power to the individual trigger switches that then goes to the coil in each device’s relay (and the actual device power feed comes from the SH150).

now, I CAN think of a way to make an IGN-triggered power switch for the SH150 using the same solenoid I’m using for my primary winch power cutoff, but that’s a lot of wasted space and effort for redundant IGN control.
