Fusable link was in series with the output side of the brake switch. Light are now working.

Hello

Interesting,

This must be a add on by the flat bed installer.

 

The wiring from the brake switch goes to the turn signal switch from there out to the lights and the power comes from the A side of the power supply should be hot all the time.

 

Thank you for using JA!
