You should hear the relay "click" when the brakes are applied.
I will revisit this. Was away from the truck all weekend. I did have the relay wired to the cold side, click when brakes applied. Pulled it to check/deal with resolving tech 2 status
The "released" status on your TechII, was that showing with the brakes applied? It shoud be the opposite if so, and should match the brake pedal, so when you apply the brakes it should say "applied" and when you release the pedal it should say "released".

Yes sir. No brakes applied and showing applied. Step on brake it shows released.
Determined to figure it out this week.
