Sambighossmack Posted May 31, 2019 Share Posted May 31, 2019 I have a 2002 Mack ch valueliner and I’m required to wire in a park brake alarm for work that which needs a trigger from the door switch and the park brake switch or light. I can’t find the park brake light on the dash and am led to believe that it doesn’t have one. Is this the case? Otherwise where is the light or switch?

Mack Technician Posted May 31, 2019 Share Posted May 31, 2019 (edited) See attached..... Leave the light circuit alone and break in at the sensor manifold.

Sambighossmack Posted May 31, 2019 Author Share Posted May 31, 2019 The wire vj1-10 for park brake signal to vcu does not exist on my truck.

Mack Technician Posted June 1, 2019 Share Posted June 1, 2019 Good, install the sensor and you will have exclusive rights to wiring into it. Pay attention to whether you want normally open or normally closed.
