Wiring side flood lights

Nowadays with multiplex wiring etc l think I'd do what cowboy suggested. Simpler and easier in the long run. Plus if there's an issue it won't affect the oem wiring. I had lights on my steps before. I would suggest using the top step. The dirt and spray down low will have you cleaning them a lot especially the wiring. Anyways good luck and they are nice and discreetly mounted.

 

Are those your only utility lights? If not I would tie them into the other utility lights. I would also agree with special-k on mounting under top step. They are just too handy for debris on bottom step.

 

As far as I know any lighting tied into the Sam cab has strick limitations on the amount of current available, if there is more than it expects it will decide there is a fault and shut the circuit down.
On my Cascadia I know the computer shuts off the utility lights if the transmission goes into high range, it assumes that you forgot to turn them off.

 

I would be tempted to mount them off the triangle brace for the upper step. It looks like you made a riser so that will bring it out some. Just be sure you or someone else won't catch it on their foot climbing in. Thats where l mounted mine years ago. They were better for backing in on a angle than going straight in

 

Utility lights are powered at the X3 Connector Pin 7 (ground at pin 21) at the sam_cab. It is an unfused logic controlled output. Your best bet is to probably power them off a relay and have the control side of the relay hooked to your existing utility lights. That way you don't add extra draw on that circuit.
