Check your Glow Plug Relay with a DVOM set to Volts-DC. Ground one lead of the meter and with the Pos lead touch one of the large posts. Have someone else rotate the key to run and what is the voltage on the post? Quickly move to the other large post and what is the voltage there?
Brake box slide? Are you asking about the slider on the trailer brake controller?
