I have a 1987 SeaRay Seville with a Mercruiser 175/v6 and I am trying to diagnose / fix the trim up on the handle. The trailer button works, but not the trim on the thumb switch. I am wanting to bypass the trim limit switch to see if that resolves it. I was going by the diagram in the image I attached, and I split and connected the blue-white coming from the control handle to the blue-white going to the plug that then goes to the the tilt/trim pump. It didn't work, and then I noticed the purple wire also. Am I connecting these the right way to bypass? Thanks in advance for the help!
