wirring auxilary lights

Hey guys im wiring up some lights and i need to pull 12 volts from inside the cab and i dont want to use the radio wire because i already have some stuff coming off of it. My question is can i pull power from an unused fuse slot in the fuse box and if so which one is best im running 2- 55 watt trail lights

best to run off the bat. if you can try and use a fuse in the line as well. also make sure your grounds are good. big power like that i would stay away from the fuse box. little things like guages and what not are not so bad tho

You are talking almost 10 Amps thats a lot to draw from any source little lone the interior Circuit Panel not to mention the possibility of a fire from a shorted wire.
IMHO Best Bet… Get a 30 amp Relay and run a fused 12 ga wire directly from the battery to the relay, pin 30, and then from pin 87 to the lights.
Use a low amperage power connection inside of the vehicle for the switch and maybe an LED Indicator light only nothing more.
Power Point inside of the vehicle to the switch, to pin 85 on the Relay.
From Relay pin 86 to Ground.

Simple and straight forward.

PM me and I will send you a write up pn “How to do it the right way the first time”.

I need to know what you did ?
How did you wire the setup ?
What connections did you make to what ?
Things like that.

I can’t say for sure what happened, so please tell me about what went down.

i wired it like the pic of number one in the how to wire things correctly in the stickys. Then double checked with what you said and made sure it was that way, Wondering if it could have messed up the starter or kill the battire

OK I found it and looked at the pic, IF you did it according to the pic then there should be no problems.

Did you disconnect the battery Cable when you connected the power to the battery ?
If so , you might need to remove the battery cable again, clean it really good and add some contact paste and put it back on.
Everything else is by the book.

Again funny how just a little move and the connection goes bad, hopefully.

If you did the wiring as the pic then there should have been no problems UNLESS there was a large enough spark or load on the main fuses.
If so, then check out the fuse panel under the hood and see if there is a fuse blown, which one do not know, check the book or the web for what fuse goes where.

Sorry I can’t be of more help, this is usually not a big deal, add the relay, add the power connect the light and sw bing-bang all done.

Let me know how you make out.

I fixed it as far as i know lol. It was really simple and stupid to be honest. The ground ring is broken and dosnt make a great connection so i have to get a new end for it and fix that wired up the lights and they work awsome.

Here is another thing that can be done with grounds.
When you run the new ground wire, if you do, run the negative battery cable to one of the starter bolts instead of the head or maybe two connections.
This will allow the starter to get a good ground path.
