No Running Lights...HELP!!

Hi everyone...



About to get on the road so i decided to replace all the lights on the exterior of my trailer.



The problem is now all the running lights do not work.



Heres what i have checked so far:



1. took apart the 7 pin. not it.

2. checked all lights for good ground. not it.

3. Tow vehicle is 08 tundra. checked fuses...not it either

4. screamed.several times...did not help. but felt better.

5. cleaned connectors of all 7 pins with wire dryer...nope.

6. post to the forum...for help...



If anyone out there has any suggestions. I will say the rear running lights were not working prior to my changing them out...



The turn signals work fine. the brake signals work fine.



All running lights are on vacation.



It feels like a no power issue, or blown fuse...but is there a fuse on the running lights?



Help me...
