Hey guys, so I'm trying to figure out what wires should go where. My tach only works on positive side which lets me know there is other issues here.

ok, green is tach!
The black wire leaving coil going to dist connects with another black.
The thicker black wire on same side loops around and has a yellow which is also connected to other side of coil.

Is the truck running? If so, what is the problem?

Maybe I did not understand the issue. Is it that the tach does not work?
I do not know, but seems the module breaks the coil connection, so tach on either side of the coil should work. Wiring diagram does show the tach to the - side.
