Tried this today using Up Hill Bill's method of adding in a piece of wire rather than trying to make the marker wire fit. Even bought a solder gun and heat sink for the splice at the marker light. Was surprisingly easy and although my splices don't look as neat as Bill's - everything works yea!! and I learned how to do something else myself. Priceless.

Might be a silly question here, but I have zero wiring experience....

What happens to the other ends of the wires you cut? (the black marker wire on the connection side, and the white wire on the front bulb side) Do those just get capped/taped off and left?

I think I want to try to do this when I put the flares on. I'd love to know the answer to the above question too

yep, but the only wire left dangling to be capped/taped is the black one.

if you have more than one left dangling on each side something is not quite right

remember, you are splicing into the flasher circuit, not cuting the source wire to re-route.

you are only changing the path to ground, not reworking the whole lighting circuit.

Got it. Thanks for clearing that up. I was thinking I had to also physically cut the white wire.

I would think a normally closed relay would do the job just as easy. Have the side markers main power go into the relay to side marker and have the signal light control the relay. That way the side marker works just as usual then when the signal light is turned on it cuts power during power and back on when no signal. It would make the side marker blink at opposite times as blinker but would still blink non the less. A relay would be pretty cheap and all you would need is a wire to run from the signal light to the relay.

you're over thinking this.

the relay is unnecessary unless you want to run a completely new circuit which is much more of a PIA than it is worth & pointless.

cut the black wire at the side marker
connect the cut pigtail to the outside wire on the turn signal with 4-6 inches of wire, a butt connector & wire splice tee.
leave the cut black wire hanging.
solder if you like but not mandatory

that's it. <$1 per side
this is incredibly easy & should have come this way from the factory.

Thanks for all the pointers. Side marker lights are now also blinkers. Great mod.

I cut the black wire about 1" away from the plug behind the grill. Leaving plenty of slack to tap into the white wire furthest away from the black wire on the front marker/blinker. I used those blue wire splicers. Snapped it shut on the wires and tested. Put on four way flashers and bingo everything working. Tucked everything back into the wire looms and warped up the rest with electrical tape.

I don't believe this will work if LEDs are anywhere in the circuit.

So the question becomes:

Does the PWM issue affect the turn signals as well as the main lights & fogs?

My guess would be most likely yes since the factory ones are incandescent.

Hilldweller you there?

Thanks for the write up! I just finished this one myself. I was able to reach the wires without removing the grill. I have a 2011 and if you look right above the bumper and under the fender you'll see both of the plugs for the lights and will be able to reach in their easily.

Since LEDs have a polarity, ie current can only flow one direction, there would need to be some extra steps or circuitry added to make this work with an LED marker light. It would not be too difficult, a simple full-wave bridge rectifier would probably solve it.

The standard incandescent bulb does not care which way the current flows so it works just fine.

You took the words right out of my mouth, especially the simple full-wave bridge rectifier part.

With the change to Standard Time and daylight/dark hours it seems appropriate to resurrect this thread. Especially useful are posts 24 & 25 by Uphill Bill. This mod is super easy and a great safety enhancement.

I concur, I did this and am really happy, kinda excited about it. I showed my wife.....lets just say she was less than excited by it. Guess she just doesn't understand.

I did this today am feeling like I'm pretty cool. Lol Thx to the OP.
Some comments to share: -Taking the grill off gave more room to get my paws in there vs going in thru wheel well. -Remove harness from turn signal unit vs removing bulb from unit and having it dangle. Figured out you slide the red tab in and squeeze black clip to detach harness from unit. -Used vampire clips but mod didn't work until I went back in with pliers and gave it a good squeeze. -Keep band aids in jeep. Freezing cold, cut finger, bloody blood. All for side blinkers....so worth it.

Yep! On all accounts! Frozen fingers, up to the third joint, and skinned knuckles are all part of the wonderful experience of being alive. Jeeps are great at helping to facilitate the experience!!!

Quick! Easy! awesome work people!!
No scraped knuckles. Easily done right through the wheel well in 15 minutes total time! NICE

Same here, I didn't have to remove anything to access both wires. Having the right tools, and a good shop light, really helps.

Instead of soldering, I just bought the crimp on splicers for 14-18 gauge wires (vehicle has 16 gauge wires). Snapped it in, very clean, no electrical tape needed.

One thing I did notice... Hazards seem a little crazier when lights are on - only because they blink in sequence.

Is there a way to take this one step further? As in turn signal and fender flare light only turn on for turn signals, but not with headlights or fogs????

It worked. I did the sidemarker mod earlier today. So now.

1. Lights off turn signal on - front turn signal and fender marker blink.

2. Fog lights on- fog light and fender marker are on but not front marker. Fronts blink when signal put on as well as fender.

3. Headlights and fogs on - head lights fogs and fender marker turn on but not front marker. Fronts and signal blink when turn signal engaged.

Only thing I did was clip the middle wire. I think legally I am still fine with the fender markers coming on
