Great video. I will attempt this soon. Thanks a million!

[@stunz01]

Can you list the part names numbers please. Awesome video, super clear to follow. Thanks

[@rl1106]

Thanks for sharing, such a great idea!

[@tdg0101]

Nice work thanks

[@schizzultz]

Thanks. Did a cad elim and was looking for a part number for that switch

[@dkhallal]

Getting ready to do this after switching to a manual CAD cable. The amount of hardware to engage the front axle and turn a light on is ridiculous! This will help a bunch. And helped me understand how all that works a lot better.

[@HardEarnedBacon]

Those pesky Jeep engineers in the 80s definitely put a lot of effort into this system haha

[@kepaloha]

DUDE!!! This was an awesome video!!! Thank you so much, Stuart Mair is right, can you put some part names and numbers? I need to get those connectors that you used, it was fantasitic.

I added some links to the description, hope it helps. Thanks for the great feedback!

I managed to do mine without lowering the Tcase... I think I still have a cramp from reaching and stretching xD

[@ton12loc]

Had the cad delete done for about a year now. Saw this video and some others on it. I just did it except my problem is 4wd light now stays on in 2wd too. It’s def not in 4wd and I had no light at all until I just did this. Any thoughts?

[@HardEarnedBacon]

Could be a bad switch, or maybe the wrong switch, or the switch is threaded in too far. Something keeping the button on the end pressed maybe.

Hello
So after seeing your video i have tried to research your idea… sure not having a great deal of luck.
Question is, how long ago did you do this conversation and how is it working out for you?

[@HardEarnedBacon]

Been over 6 months and still works perfect

[@upiper71]

Hi,
Just curious as to what gage wire did you use? 14AWG?

[@HardEarnedBacon]

Yeah, 16 or 18 would be fine too

[@upiper71]

@@HardEarnedBacon thanks man

[@upiper71]

@@HardEarnedBacon oh I had one question. In trying to remove the old Tcase switch, what size of deep socket do I need to remove it? 1”?
