Tekonsha P3 Power

I just installed my second Tekonsha P3, the first came DOA. There appears to be no on/off switch. I don't see the need to have it powered up while not towing. I was thinking of splicing a switch to the power harness. This would be simpler than disconnecting the harness.

Now that the brake controller is in place, I hope to bring something home this week.
Happy Easter

I don't see any problem with putting a switch in the circuit for the P3, but I don't see any need for, either. My P3 has been powered since it was installed 4 years ago with out any ill effect.

I quickly got used to the P3's "NO TRAILER" warning and just leave it installed and on all the time. It's been set up that way for 2 years now with no problems.

Mine stays on and do not have any problem with it running either. Plus the small current running through it might help to keep moisture out.
