Hi, I have a 2011 E350 strip chassis and I am working on removing couple of pins from a harness connected to the brake shift interlock actuator. The harness is c 2127. It's in a bit of a tight spot, but I managed to get the white locking piece on the front of the harness backed out 1/8 of an inch or so, it really feels like I might break it if I try to pull it all the way out. Wondering if anybody could give me solid information on how to back out pins on it. Trying to avoid buying a pigtail harness. The picture attached is a replacement pigtail harness of the exact same type I'm looking at.

Is that a safety feature you wish to disable?
