Cigarette Lighter Wiring Photos?

First off, I thought I could handle wiring in a Cigarette Lighter into my Jeep (found an original lighter online). After searching the boards/internet for a few hours on the correct way to do this, I found it to be a little more complicated then just wiring it directly into the Fuse Box. There were several threads that discussed how to do this, but not really any photos to go with the explanations.

That being said...does anyone have photos of how they wired their lighters into their fuse boxes? I found there were two ways to do this. Wiring through the fuse box with an inline Fuse, or fusible link or Wiring to the solenoid. Is their an advantage to the inline Fuse as supposed to the Fusible Link? Is there anything wrong with using a 10 gauge wire and just wiring it directly into the Fuse box? I definitely want to do the safe thing, so if the inline fuse or Fusible link is the way to go I want to do it.

I am definitely an amateur at wiring so photos would be a huge help. I'm basically wanting the cigarette lighter as a power source to charge my cell phone and other small devices.

Thanks In Advance For Your Help!

If I remember correctly, there is a large (10ga) yellow wire under the dash that plugs into the back of the cigarette lighter.

Well, the PO had the dash completely rewired, so things arent exactly where the once were. The existing wiring is solid, but there are no extra wires hanging under the dash. Thats why I was looking to see if anyone had photos of wiring they did or was original to the Cigarette Lighter.

There's a red ignition wire with a little "L" shaped rubber end that goes on the cigarette lighter. I just fixed mine.

The large yellow wire goes to the volt gauge
Agree on the red wire, with the 90 degree connector
. Its comes from the fuse block, and uses the same 15 amp fuse as the backup lights. It labeled B/U LPS. This is from my 1978 owners manual. It works when the key is in the on position..

I'll have to check the current wiring job since its been altered and see if I can identify the wires you are referring too...

Ok I checked the fuse box, and there isn't a B/U LPS 15 amp fuse. There is an ignition/LPS 15 amp fuse, but no wire coming from it? Incidentally, there is one yellow wire coming out of the slot labeled clock, but there is no clock so no telling whats really wired in there.

I kind of figured this would go this way since the dash has been rewired at least once before I got the Jeep. Also, dash was missing the cigarette lighter, ashtray and glove box. So I figure the PO gutted those items a long time ago.

Any other suggestions? I'm open to anything. And thanks again for the help!!

I ran some 16 gauge wire from the lighter to the fuse box in an open slot. Grounded it to the dash and haven't had a problem since

This sounds like something I can handle, how did you ground it to the dash? Thanks for the help!

some may disagree with me, but grounding to the dash is iffy. you would be better off grounding to the firewall, or an existing ground wire in the harness.

I mounted mine near the stereo. Put a screw into an open hole that was on the bottom of the dash. Grounded just fine. I agree with the precious post about grounding to the dash can be iffy. However i have never had an issue with it

it really depends on whether there is a clean metal to metal around the bolt holes or if they are filled with paint/rust.

Here is the fuse box schematic, if it is of any hep in working out where it comes from. It is on the 10 Amp ACCY fuse (Accessories, includes stereo, cigar lighter, cruise) and goes down a red wire.


The wiring diagrams show a right hand connector on to the back of the lighter and then a ground from the lighter to the black wires under the dash that earth various dash lights.

Hope this helps. As long as you get the right connection into the fuse box I would be tempted to look at an improved ground system for the dash and not rely on the steel structure of the dash panel.

I actually just tore my dash apart this evening and the yahoo that owned my CJ prior to me grounded the lighter to the dash. The clincher is that he/ she didn't even bother to scrape the paint off to provide a better ground.
Either way I am a firm believer that the dash shouldn't be used as a grounding location. Do what you want as its your rig, but I think many would agree not to use the dash.

So could I hook a 12-16 gauge red wire into empty slot labeled cruise in the fuse box? The wire that is coming out of the stereo slot goes directly into a bundle of wires for speakers and the head unit...

I have a copy of the wiring diagram which is sort of like a foreign language to me...haha, plus I have the Chilton guide for my Jeep but it's very non specific about Lighters and their hookups. So between that fact and since the dash was rewired I wanted to see photos of what folks have done so I could do the same. I'm trying to get a visual of the grounding and the wiring connection to the fuse box would look like.
