The 5 pin module is for distributors with the ESC (Electronic Spark Control) system. This is the one that has the wires going through the firewall.

The ESC distributor plugs into a control module behind the glove box. All the ESC does is control spark knock. You will notice the knock sensor screwed into the block in front of the starter.

I have replaced all the mess on my truck with an MSD Pro-Billet HEI distributor.

Hope this helps,
