A little help please. I want to dashmont a Sunpro tach to my 2010 427R. I'm sure there will be some why do that questions, so here goes. I wanted one more chance to own a really bad ass car before I ran out of time (I turn 66 next month). I found and bought a 2010 black 427R with only 1700 miles 3 months ago. I have added a Wilwood big brake kit with black calipers which really turned out nice looking. Back when I was alot younger most of us had the chrome Sun tach mounted somewhere and I want that look again. My questions are where do you pick up the read for the RPM's on a DIS unit and also the location of the wire for dimmer control to provide lighting.
