With the turn signal on, engine off, I can hear my unilight modual intermitantly buzz as the signal flashes. I thought this was really strange so I figured I'd run it past you guys. My tach needle will also jump with the signal-I would assume they are related somehow. Any thoughts on this??

Just a voltage spike from the contacts in the flasher. The old points had a capictor which absord any spikes. Any time you have contacts open and close you get a small spike. Just dont use your turn signals with the car off and youll be fine. While the car is running the spikes get eaten up in the system so they pose no problems.
