Question:
Greetings -I am preparing my 2010 Honda fit to install the Roadmaster brake-lite relay RM-88400. Chris B indicated that I should look for the green/silver wire coming from the brake light relay. I am trying to find the brake light fuse to pull prior to beginning the work. The fuse box label does not have brake light switch. Would it be fuse 11, ABS/VSA or fuse 37 labeled ABS/VSR FSR? Any help you can provide would be greatly appreciated.

Helpful Expert Reply:
Pull the fuse panel beneath the dash to attach the red power wire to the hot side of any fuse that is powered only when brake pedal is depressed. The location might be 11 or 37 but you will need to test for function using a circuit tester like # PTW2993.
See the Roadmaster video I attached of the at the 3:26 mark to show you how to test for function but the fuse panel will be different (2008 Honda Fit) as fuse panels have changed throughout the years.
I also attached a video of the circuit tester.
