Question:
I purchased wiring kit RM15267 for my 2018 Jeep wrangler. On your web site it states that I MAY need a brake lite relay RM88400. Do I need this part or not?

Expert Reply:
What braking system are you planning on using? If the system presses the brake pedal of the 2018 Jeep JK Wrangler like most do then yes you do need to use the # RM-88400.
The reason for this is so that the stoplights of your Wrangler don't override the blinker circuits of the # RM-15267.
I attached install videos for both kits in similar 2017 Jeep Wrangler Unlimiteds.
