Keyed 12 Volt Source Under Hood

[joe04]

Anyone give me a clue for a 12 volt keyed source under the hood. For seat heaters, power lumbar, snow plow controller. Don't want them tapped into dash fuse panel. Sparkstech?

Just make clear you are looking for a 12v source to add those 3 componets in?

yes. I had them tapped into the dash fuse panel, Plow on the 15 Amp 4wd fuse, and the Balance on the heater fan fuse. I wanted them to be independent of the dash panel box, and wired in a stand alone panel for 6 additional fuses, but still would like them to turn off with ignition. Any ideas? I also looked at underhood box, but both stud 1 & 2 are hot all the time.....

Do you have relays on any of these componets?

No, I have been looking at my plow set up. It goes through a solenoid to turn power on. I'm wondering if that would be a solution. I have the new fuse panel wired through a circuit breaker, I tapped into the battery, but not thinking until I had it all wired, everythings protected, but hot all the time. If I forget the seat heaters, or plow, I'm sure the truck would let me down after a day of sitting there. Thanks for your help....

Is there a high enough (40-60 amp) source keyed under dash as an alternative?

Since you have every thing wired up to a new fuse panel the best thing would be to use relays and tap them into a circuit that powers on when the key is on. By doing so you reduce the chance of overloading or melting wires.

 

Great job add on a fuse block. Most people will just tap into any power wire they can find which can cause more problems and more money.

Would that be at the dash fuse panel? I've never gotten into using relays in the past. Do you have any suggestions as to where to tap into power for this? I like good mechanical connections, with a stud and nut, instead of fuse taps, which I've seen too many problems with in the past......Again, thanks!

the relays that you would be using looks like this. One 12v power wire from the battery with fuse, One wire to the componet you need to power up, One power (Switch Wire) wire from a switch or ignition power source, and One ground wire. SEE PIC

 

Gm does not have all the wire diagrams loaded up for me to find the perfect wire to use. Your best bet is to tap into SEO ACCY fuse. This would be your switch wire to the relay.

I'll say it one more time. Thank you! I'll pick up a relay tomorrow, and get started on this....

Hey Jonesy55,

Just wanted to thank you for all your help Sunday evening with this project. As an update, I picked up another plow solenoid, which I believe is equivalent to a relay, maybe a little larger and heavier duty. I proceeded to wire it in, and used the Rear Window Defroster Fuse (10 amp), for the "on" signal. Now, when truck is running, all my "appliances" are HOT, when truck is shut off, so are they! Thanks again, I feel very comfortable having a stand alone distribution source. Have a good one!
