So I plan on buying a tach for my sled since it doesnt come with one and I want one. It was an option on my sled so im assuming I have everything I need to hook it up except for the gauge. So can you guys help me by telling me if I have everything I need to hook it up. The brackets and hardware come with it, so Im just worried about the electrical. Attached is a picture of what I believe to is to be the tach hook up. The plug has 6 holes, with four of them with connections. I can tell you the colors of the wires if you need them. So when I get the tach is this all I have to do, is just plug it in? It is a for a GEN II black tachometer. If someone has one of these it would be great if they could run out and look at this and tell me thats all I need.
