To make a Speed Hut Tach work with a Diesel

If you use a 3 wire inductive pickup like the Cherry I used, the key to making it work properly is the proper pick up resistor. Here you see a 1K resister soldered between the +12 lead and the tach signal lead. In image 2 you see how I tucked the resistor into the top of the Weather pak connector.
