TJ in 4-low still needs clutch to start

Hi, hoping someone can help out here. I keep reading that in 4-lo I should be able to start my Jeep without the clutch. Tried it, doesn't work. Could something have been adjusted, changed, incorrectly done, etc?

I do see the interlock option with fuse bypass but I seem to read repeatedly that in 4-low this can be done per factory functionality.

As far as I'm aware on the tj's or atleast the newer ones that's there's a clutch safety switch so no matter what the clutch pedal must be down to start the jeep regardless of t-case position. I think the 4lo concept comes from the fact that the gears are low enough that the jeep would and could start in gear without the clutch pedal down but you would still have to bypass the safety switch in order to get this to happen

Putting it in 4wd low does nothing, for 1998 and newer TJs the only way to bypass the clutch interlock is with the fuse. For 1997 TJs its a different procedure and not a fuse.

The 97 TJ uses a defeat plug...look under the dash above your clutch, you'll see a plug that can be inserted into the harness. It's in the owner's manual.

The 4-low clutch bypass only works with the Rubicons, but you can place a fuse in the clutch bypass slot and the bypass will work no matter then t-case position.

According to the Owner's Manual, for my 2001 Sport the instructions on page 132 for the Clutch Interlocking Ignition System. In the fuse block behind the glove box, put a 20A fuse in the Cavity marked (f20). This will allow starting the engine with out the clutch pedal being depressed.
Lots of information in that little book.
