simple load light out? Headache!

I'm trying to figure out what went wrong here... I put 2 LED work lights wired to the load light switch (turns on the light on the back of the cab) and they were working fine, I then move the location of the lights a few inches and hooked up everything the same, power to power and new ground at new mount locations. NOW I flip the switch and they don't turn on. YES I CHECKED THE FUSE AND RELAY lol.. I checked all fuses and they're all good, checked the relay and it clicks. I don't have power at the dash switch and the little green oval that turns on when the switch it's "on" doesn't come up. I know I need power to the switch but where did the power go if it was working just fine before!?? I'm breaking my head per this, please help, what am I missing.

2010 Peterbilt 384, 48" sleeper.
The Load light fuse and relay were found under the sleeper bed, I didn't find anything on the fuse box next to the clutch, or the one behind the dash. Please help! I know I'm missing something

My load lights are also not working. The green light on the switch comes on but not lights. What relay and fuse do I check, I don't see anything marked for load lights. It's a 2014 Kenworth T660. Thanks in advance

New trucks you usually need to go in and reprogram the "computer" to let it know there is a larger load on the system so it doesn't shut things down thinking there is a short.
