I don't understand how this has a connection.

I have a 1996 F350 7.3 dually cc. My cruise control wasn't working, so I replaced the switch that is located on the steering wheel. After that the cruise control worked, but I then noticed if I turn on the right signal, it will turn the cruise control off and the motor jumps up about 300-400 rpm. Then to add to it, I see the speedo bouncing around and that causes the truck to surge when cruise control is on.

I just don't see why these have contections. It's kind of comical. Next I'll honk my horn and the headlights will go on. On a serious note, I'm thinking something with the PCM?

Has anyone else had any issues like this?
