Momentary Clutch Bypass
So i know there are a few other threads on this topic, but i have not seen one with a solution like mine, so i thought i'd share. The purpose here is be able to start your manual JK without having to push in the clutch pedal. Being able to start the vehicle from outside, or from the passanger seat are just 2 examples of the benefits of this.
Some people have hard wired a solution like this. I didnt like this option. There are many posts of problems arising from this (ie. people dont know about it and start er up in gear). You also have the problem of no cruise control.
The other option is a toggle switch. When "on", no cluth needed. But suseptible to the same problems mentioned above. When "off", no benefit at all.
The option i went with, is a momentary switch:
I got these in a 4-pack for about $4. Why is there more than 4 in this pack? Good question! Be careful. I first bought the wrong type of switch. Momentary switches come in 2 types, "normally open" & "normally closed". You want "normally open". This means the circuit is broken until you push the button, that completes the circuit.
The first step is to tap into the the correct wire in the engine bay (photo and info taken from https://www.jk-forum.com/forums/show...out-clutch-YES)
Of these 3 clips, you need the one closest to the radiator. Unplug it, then find the yellow/red stripe wire. You need to splice into that. This wire leads to ground when the clutch pedal is in. This is what we are trying to trick our JK into thinking. So take your spliced wire and run it into the cab. Next, you need to remove the lower plastic cover of your steering column (sorry no pics of this part). In the 2011, there is 1 T20 bolt in the middle of the bottom of this piece of plastic. Then on the outsides, there are 2 holes that have T15 bolts buried inside. I needed to go out and buy an extension to be able to reach them. Once that lower piece is off, drill a small hole near the key hole, and mount up your momentary switch. There are 2 pins on the switch. Its purpose is just to sit in line. So run your spliced wire (from yellow/red) to one pin, and other to ground. Now when you hold the button in, the jeep "thinks" the clutch is in. Here is a pic of my finished product:
so now all i do is turn the key while holding the button and RRUUUMMMM she starts right up. I love this mod!!!!
(ps, nevermind those 2 upside-down photos attached)

Great idea. My wife is always complaining that she can't start the jeep from the passenger side when she gets in it and I'm still loading stuff. It sucks in Florida when I is always 100 degrees out. I'm working on the jeep this weekend and I'm adding this to the list.

I looked at the pic of the momentary switches. You said there are two types: momentary on and off. Does it say it on the package somewhere? Also, If I choose to use a toggle switch and it is in the off position would I still be able to use the clutch at that point? My thought is, I wonder if there is a way to wire it as some sort of safety feature/ kill switch where it won't start unless you have the switch "on" which could be hidden somewhere?

As for your other point, i have thought quite a bit about this since installing this switch. thinking, can i disconnect the clutch, so the switch is the only way to start it? seems like it would be harder to steal the jeep, i mean whos looking for a button on the steering column? Then i thought, wait a minute, i should have just made push button ignition. I still think i might do this, but have no idea how to yet.

I have been researching this too, although I can't find anything on it due to the complexity of the new ignitions. The best idea I can come up with is an overall power kill/switch. basically running a switch to the ignition fuse in the fuse box and use that to switch on and off when I want to start it. This way, the jeep could be started normally but first the operator must turn on the "main power switch" which is hidden in a place of their choice.

(with switch in off) With this you can put the key in and everything works, lights, radio, but when you try to start it just keeps turning over and over and over so it sounds like the vehicle is just broken down. Some thieves are smart and if you disable the power with an actual kill switch so nothing works its rather obvious that something is blocking the power, but this way everything works including cranking. Just doesn't start
On the other hand this mod (this thread) is actually exactly what I was looking for. In the TJ you just unplugged the module by the clutch. This is a rather smart way to do it so you still keep cruise I'll have to pickup the switch this week and give it a shot.
Thanks for the write up!
