Hey folks.

Today I finally installed my two rocker switches. One is not hooked up yet as I plan on hooking up rear lights. But I wanted to wire my bull bar light up.

Issue is I don’t want constant light on the switch so o wanted to tap into the cigarette lighter/12 v plug as it’s ignition only and as far as I know we don’t have have blanks with power.

I bought a mini fuse tap but it didn’t fit. What style or size tap should I look for ?

Also, does anyone know if this is safe ?

I am using a relay harness that came with bull bar/light. It has a + And - off light bar. Goes to a relay which goes to 12V power source and a harness that goes to switch. Do I need to wire power to switch separately or can I use the power from fuse tap to power light bar? I’m an idiot when it comes to electrical. So instead of using positive and negative off battery use negative off battery and positive (hot) in fuse box? I’d have to cut the batter connector off the positive and add a fuse tap.




Thanks!

Using a Micro2 add a circuit fuse tap at the fuse box should be enough to run the light bar.
My previous 22" one pulled about 4 amps.
Couple of reverse aux lights pulled 1.1A each.

I’m confused. What’s this have to do with fuel type and style? Furthermore, I didn’t know that fuel had different styles. For what it’s worth I use 87 as I have a 31 gallon tank and a 6.4 hemi and already feel kicked in the nuts when I buy gas at $2.40-$2.50 a gallon. No way In he’ll I’m paying for premium

So no need to run separate power for light bar and power to switch? The positive wire has an inline fuse and it goes to the relay which has a harness that goes to the switch.

I just don’t wanna fry my fuse box or ECU or something else with a fancy and expensive acronym

I swear it said fuel type earlier. I was aiming for humor but I suppose I missed the mark on that one. [emoji2369]

Totally understand your caution with these trucks.
I think F93 can handle the load unless you've got some power hungry accessories also using cigarette outlets.

Like you I wanted to be on the safe side & have extra 12V sources so I added fuse blocks.

Yes, if you want the switch off when truck is off, you're got to tap into the cigarette switched 12V for the switch.
I think most kit's assume you're wiring straight to a battery connection, and the switch uses the same 12V to trigger the relay coil. At least one of mine kits was wired that way.

Part of my 12V wiring with F93 tapped for my light's switches:

Awesome! That digram is intense lol.

I literally have nothing except the bull bar light. I don’t use the cigarette lighter plug at all. I charge my stuff using the USB plugs.

So should I keep the relay hooked up to battery like normal and then splice into the harness that goes into cab to the switch and route that back to fuse box and then a tap? Or the positive straight to fuse box with fuse tap? Sorry. I’m an idiot like I said.

For your lights, I'd run 12V to the relay contacts that power the light bar.
Either tap into the cigarette outlet wires under the console or put in a Micro2 fuse tap on F93 and run that to your switch. Whichever is easier for running the wires.
This way you don't worry you're overloading the fuse tap b/c you're just using it's switched power to energize the relay coil.
