I know the module is numbered with 4 ,2, 6 on the front. When i see pis of 85's that have changed it seems 2,4,6 plug wires on cylinder side go to the back of the module. I replace my plug wires with MSD wires that said they are for 84-87 GN but number 6 is quite a stretch to the front of the module. Thats what is making me confused.
