adjustable switch cable length

[pluckyman]

M2000 extreme power puck 98-00 CAT 3126.
1999 36.5' Damon Ultrasport motorhome.

Since I own a motorhome the adjustable switch cable is much to short. Can I extend the length of the cable without causing problem with the power puck?

Yes, if done properly and soldered it will work fine.

I also need to know which connector on the harness goes to which sensor. They are both the same and not marked.
