Undercarriage lights attached to Incab bed light switch

i am looking to hook up 2 53inch LED light strips to the undercarriage that will work the same as my bed light. Want to hook it up to the in cab switch that has the on off and door function. And it also works when unlocking the truck. Just wanted to see you guys ideas on how to go about doing this and what wires to connect where.

Just don't use those vampire taps. They are bad mojo.

 

Checked it out. Seems legit. They don't tap into the switch itself but the plug in the lock panel and the ground there also. Thanks for the input.
