Jump orange wire to light blue wire and let me know if lights come on. Thanks.

Customer: replied 10 days ago.
can I get back to you in a few days the truck is up at my sons collage, I did replace the sw so I know that's good, if the lights still don't come on after jumping what can I look for, I just want a number of things to check when I get there, thanks Dave
Expert:  Dan replied 10 days ago.

If lights do come on when jumping switch that means new switch is bad or it is installed wrong. If not then there is a problem on the light blue wire somewhere between switch and splice 100. Here is a wire diagram and picture of splice to help with testing. Let me know how it goes, you can reply to this answer at any time without additional fees. Thanks.
