Hi All,

I'm fitting an old Mark12 Tekonsha brake controller to the P38 for towing the Tvan. I have a couple of questions for anyone with experience.

1. It appears that the trigger wire needs to be a positive feed, however the P38 uses a negative trigger to the BeCM, any suggestions on reversing this?

2. Will I need to put in any diodes to prevent back feeding?

This controller was given to me for free, but I have access to the loan of a Prodigy if this would be better.

Any help appreciated.

Stu
