On a 96 502 MPI the coil has 4 wires, one heavy red and a white from the main harness and the other has a brown and pink that go to the distributor module, I am installing a MSD 6A box and the instructions say to tie two pinks off the coil together and two whites together but on my coil that would be the white and brown together and the heavy red and pink, is this the right way?

Use the MSD GM harness adapter (PN8876) it makes it easy to hook up and, equally important, easy to reconnect without the MSD box should you have a problem.

That harness would hook up the same way the MSD diagram shows, I just want to make sure the wires on my boat are the same in the diagram despite the color difference.

The nice thing though is if you use that adapter harness if boat should ever act up where you think box is failing or failed you can unplug everything like dave said and plug it back in like stock. It seems like my stock 2000 mpi harness has different color wires than what msd says but it still works,I think the msd instructions were written for gm trucks and cars using dual connector coils so that might be why it looks slightly different than what the instructions show,Smitty
