Accessory Key Position

[UMGixxer]

For those with aftermarket hu and speakers that are not using any harnesses. I know the RAP powers things for like 10 mins but you lose that without the proper harnesses. So I was wondering how do you guys/gals play your a/v system with the key off since these trucks dont have an acc key position.

so u have the switched power source hooked up normal, and then u run a constant hot to the same wire but just leave it off until needed??

i splice a wire in from my constant to a toggle switch out to my switched so i can turn it on when i want and off when i dont want it on

your yellows your constant, your reds the switched the grey is where you tie in

so where you connect your power to power (constant) you hook up another wire and extend that to your toggle switch then from the toggle switch you wanna go out to your red switched on the deck

hope the picture helps

I also have another solution for you.. You wanted to use it only when in the accessory position, so I'm taking uhoh's idea, you could also get a test light and find which wire in your ignition is your accessory ( + ) and hook a toggle up to that to run your head unit. Uhoh's idea is the best, but the only problem is when you forget to turn it off, you can drain your battery. My buddy wired his up the same way, and his head unit is possessed and turns on whenever so it drains his battery often. Also, might want to fuse your toggle somewhat near your 12v connection so if it shorts, only the fuse blows and no fires happen.

Just my .02 cents. Feel free to use my advice or not.

Ahh, makes sense lol. That's what I get for reading fast and thinking. Oh well. You could always just install a different ingnition with an accessory.. but the toggle is much easier
