Third Brake Light: Logic Module or Multifunction Bypass?

[NickyV]

I'm looking for some advice. And this is something of a two-part question.

 

I am planning to finally get the center brake light on my trailer working like it should. But I'd really like it to function as both a running light and a brake light — but avoid the issue of flashing.

 

I understand from other posts that there are two methods to do this: Getting a logic module or bypassing the multifunction switch. But what I have been having trouble figuring out is if there is a best way to do this while also ensuring that the truck cap light functions like a running light and a brake light.

 

When I search the web for logic modules, I'm not finding anything that clearly states they will provide this functionality. And come to think of it, I'm thinking I may have to do some additional cab-to-cap wiring if I want to go the bypass route: Running one wire for the running light circuit and another directly from the brake.

 

Has anyone out there set up their third brake light so it works as a running light and a brake light? If so, how would you recommend I do mine?
