So I found some wiring descrepacies with what the dude did and what it says to do in the instructions. There is one red number one wire that goes to the amp guage. There is another one with a pigtail . I assume this is the ignition to light switch that is at the top of the page.. The problem is the lead doesnt reach the light switch. So he had the taped lead going to the amp meter and ignition. But still I only have two wires to the amp meter.
These are my instructions.
