Replacing the MC in the wagon. The OEM single circuit MC has a Y-block/circuit splitter on the end that also accepts the pressure switch for the brake lights. Obviously, the new Willwood MC doesn't have a spot for the brake light pressure switch, and will need to figure out the best way to install one.... Here is the old MC with integrated Y-blockswitch on the left end in the pic.... I think I will need to plumb in a 3-way junction block that will allow the brake line to go 'through' using two fittings and put the switch into the 3rd fitting? Sort of like this set-up (although maybe I can get it from FLAPS a bit cheaper): Earls PK0017ERL Earls Brake Light Switch Kit - Pressure Activated w/ Tee Is this the best way to do it...or is there a better way. Does willwood make anything specific for their MCs that is a clean set-up? Last question....on the cj, I have 2 brake light switches: one on the front brake line circuit and one on the rear circuit (although I am not sure if the one on the rear actually works). Is it best practice to have a brake light switch on both circuits, or is it okay to run it on only one circuit?
