Brake Buddy with Cool Tech harness on Jeep JK?

CoolTech says that regardless of whether you need to unlock the column (i.e. new jeep vs older jeep), you will still need to disconnect the battery or pull the brake fuse. The issue, according to CoolTech, occurs when you are braking AND have the turn signal on. The MH will send a flashing turn signal through the CoolTech harness during this condition, but the Jeep will send a brake light only signal during this condition (b/c the Jeep doesn't 'know' the MH signal indicator is on). The result is a solid brake light on the jeep that is not flashing. Now once you've slowed to a speed that your braking device of choice is no longer activing the jeep's brakes, this condition will go away and the jeep's light will flash. Soooo, my long winded post is just to simply say CoolTech's recommendation is to disconnect the battery or pull the brake fuse even on newer jeeps like mine (2011).

Hope this helps. Note: I have not yet completed my installation of CoolTech and ReadyBrute.....so I'm only basing the above on information provided by CoolTech (but I have little reason to doubt them).

This is why I installed a separate bulb kit on my 2011 JK. No disconnecting of the battery, and lights work as they should.

Bob, yes, no doubt a separate bulb system would eliminate this issue. But there are advantages to the Cooltech system including (1) factory style connectors for longevity, (2) easy installation, and (3) easily moved to another vehicle if desired. Obviously, those of us in this post appreciate your input.....but we're talking about our personal experiences with CoolTech, not a separate bulb installation.
