The electrican that wired my Forward I10 lift didn't wire in the limit switch. I got a real good deal on the electrical in the new shop so no complaints. I haven't had a vehicle up high enough to trip the limit switch but it would be good to have just in case. My question is can I run a 12/2 cable from the limit switch down into the box and wire it between the lift switch and a 110 wire? My finger is touching the 2 wires i'm asking about seperating in the photo.

I have used the cable from inexpensive new extension cords to repair or replace the wiring on limit switches installed on trash compactors and cardboard balers. Worked fine and lasted a long time.

If its direct wire, you should also have a manual cutoff switch by the lift. (There are other good threads on the site about the code and reasons why that's important.)

I recommend checking the instructions for your lift, but I expect that your cutoff swich and limit switch would be wired through the connection you are pointing to.

Check the owners manual for your lift.
Power should go to a 2 pole disconnect switch first.
Then to the limit switch where the limit switch is in series with one of the legs.
Finally a cable from the limit switch goes to the junction box on the motor unit.

I have a 2 gang box mounted to the side of my lift. Power goes to this box first.
My 2 pole disconnect is in this box. Power then goes to the limit switch and finally to the motor junction box.
It's all in conduit.

Before I purchased the lift I had read on here about a kill switch multiple times so that was included in my wiring plan. My panel is 35' away with a vehicle to get around so having a kill switch was mandatory. I was thinking outside the box with my question to avoid adding another junction box and having to hack up the existing wiring.

If I understood your original question, it appeared you want to run the limit switch cable into the motor junction box. It’s a small box and adding another cable in there would not be the best plan.

Reroute the MC cable from the motor JB up to the limit switch. Add a new piece of MC from limit switch down to motor JB.

I would have to double check on mine, but I believe you break the black wires by your finger with the limit switch.

i.e. undo that wire nut then each wire gets a leg of the limit switch wire so power goes through it until the circuit is broken.

but yeah, check your manual to verify

Tested and verified that this will work. Thank you for help everyone.
