Need a device part II

Question

First  thanks to BOBBO for understanding what I was trying to say in my first post,  and a solution.  Never realized that the 3rd brake light is somewhat “independent” in operation from the 2 regular brake lights.  My solution might have been easier than his.  I just pulled the 3rd brake light and tapped a pair of long wires To it, then ran all hidden up to the dash.  Bought a red led tail light and a pair of 2 prong connectors and just set on toad dash.  What I was after was not to see when the brake lights were on, but to see when my toad brake pedal was depressed.  The 3rd light comes on when the toad brake pedal is depressed.  Stepping on the MH brake pedal will illuminate the toad brakes(4 diodes installed) but not the 3rd brake light.  Still have to look at the backup camera but just didn’t want to run another wire with connectors from the toad to the dash of the MH.

My suggestion was to tap that line under the dash instead of at the rear,. But it works the same way.

Wa8yxm, this is a smart car and the brake pedal comes up from the floor, not suspended like most are.  Those wires are under the floor, somewhere.  Yes, it would be a shorter run if I could have found them.  But thanks for the response.  Now looking at some way to suction cup something to temporarily hold the new light up to the windshield while being towed so I can see it better.

Dangle from the rear view mirror? Cheap and easy.
