Hopefully easy electrical fix
OK all...wiring LED lights inside Cab of '13 SCrew.
I wanted these to work in 2 different ways..first with interior lights when's doors open etc. Got that part...I hit the gray/purple stripe wire on passenger side. DONE and works correctly.
My second thought to turn on was directly from battery so I could turn them on and off anytime.
I bought a SPDT switch as told here but
ISSUE is this, No LED lights when I flip switch to battery side. I can pull off connectors and touch battery wire and LED wire..nothing. Now I noticed when I touch to this wire it feeds the stock interior white lights. They come on but LEDs don't.
Again LED's seem to be wired perfectly..they work as on/off for interior door open lighting but not from battery.
Any ideas please????
Bad switch maybe but things are the same when I switch poles on switch.

need a couple diodes , your batt wire is back feeding the interior/dash lights..
quick pic, should help understand what is happening..

I agree but don't understand. Wouldn't a good switch stop this from back feeding? And why wouldn't the LED's at least flicker when I touch the wire and whites lights up.
Sort of lost here?

I will follow your advice but need more info. What kind of diode? Are these a size thing? Don't laugh I'm not good with electrical that goes beyond the very simple stuff.

after some searching...my thoughts, your interior lighting should be less amps than a headlight curcuit so a diode of this size should be fine..leds use less amps as well..this will act as a blocker and stop the backfeed to the other lights and only allow your leds on the switch, and with the doors-with or without the switch being on.

noob :)
This will explain diodes a bit... a 1N4001 is a common diode that would work for you

do you have a test light? Also where did you wire the led negative wire to?
can you clarify "I can pull off connectors and touch battery wire and LED wire..nothing. Now I noticed when I touch to this wire it feeds the stock interior white lights."
you did grab the positive (red) direct from battery right?
