I did notice however, that these lights do not stay on 'all the time' and I believe they should when trailering boat at night.

My trailer wire connection to truck is your typical 4 wire plug.
(green, yellow, black, white)

Thoughts as to why side lights are not working ?

Thanks !
Your brown wire is the problem. It's for the side marker and tail lights. I'm assuming it's a standard 4 pin connector.
