Question:

Looking for a break away switch only for a Brake Buddy II. I do not need the coil safety cable. Would you have one of these switches? Thank you, Fred

Expert Reply:

The complete replacement breakaway kit for a Hopkins Brake Buddy II is the part # HM39340 but since you only want the switch Fred and it's a universal switch that is used you could use the part # C52010 and be fine.

Jameson I want to use this C52010 but my Brake Buddy has a + and - One Red wire and one Black wire . The replacement has 2 Blue wires does it matter which one goes to the positive on the unit? Thank you

@ErnieD it does not matter which blue wire you use as it's only going to complete the circuit when the pin is pulled.
