No lights

I just installed the ez wire 21 circuit harness in my 1955 ford f100. When I pulled the headlight switch I have no headlights or parking lights. I followed ez wire schematic. Also no lights for gauges or dashboard. Any ideas?
thanks
jerry

Not so stupid question, do you have ​​​​​power anywhere else? Did you hook up the battery?

yes truck started with no problems. The front parking lights worked when you pull the hazard plug on the side of the steering column. I still have to test the switch to see if it gets power. The headlights switch I didn't take apart yet. I will check today. check the easy fix stuff first.
Thanks

I'm not sure, but isn't there a relay in the panel for the headlights? Is the relay in?

56panelford thanks for the information on breaker fuse. I saw this in the package with the ez wire. That’s the part about direction was weak. I placed the breaker fuse. Still the same. But I traced all connections to lights and found a bad connection. Now I have lights. The other problem is the dash lights on the headlights switch show no power. Any thoughts?
thanks
jerry

Update on no dashboard lights. after many attempts at getting the head light switch to work for the dashboard it worked. But the switch worked because the it was a bad connection you had to turn the headlight witch only a certain way to work. So I am buying a new switch so I can have dashboard lights.
Thanks
Jerry

Glad you got it figured out and thanks for the update. One of my vehicles has a touchy rheostat as well.
