Autometer Tach hook up????


Just starting
I have a autometer 5 inch monster that Im putting in my car but not sure how to hook it up.... I need some help from you guys, could someone tell me how to do this or direct me in the right direction? Thanks Kevin
Did it work?

I'm soon to hook up a tach as well....did this install work?

I read 4th wire from right at the coil pack....
