Installing Aftermarket distributor?
While I was trying to rebuild my stock distributor for my 77 F150, I managed to break it, so I decided to install new after-market distributor and get rid of the Duraspark control module. Does anyone have a procedure as to how this done? My new distributor has a red and a black wire coming out of it and it has a separate high energy coil that I will be mounting to the fire wall. What I'm looking for is what wires from the stock engine wiring harness should I use to hook up this new ignition system and is there anything else I need to do, since I will not be putting the Duraspark module back into the truck? Thanks for your help.

Ray, that's what I have as well and I did purchase their coil to go with the distributor. My question is more about which wire in my original harness do I pick up the 12V ignition source from and if there is anything special that needs to be done to eliminate the Duraspark module. I would like a clean looking installation and remove any un-needed wires, like the one's that went to the Duraspark box for example, but I don't want end up removing a wire that may have been needed for something else.
Their schematic is a little unclear though, like I said earlier my distributor only has 2 wires coming out of the bottom, 1-red & 1-black and the schematic shows 1-red, 1 orange or green, and one black, which adds up to 3-wires. I would think the distributor would not need a separate ground wire since it is bolted into the intake manifold which is grounded.

I found the schematic that Ray provided from the ProComp site and it is for their PC8020 distributor. I have their PC7002 distributor, which they say is a two wire design, but when I click on the instruction sheet link for this distributor the link is no good. I know I have my instruction sheet some where:-)........

Specifically, what is the advantage of swapping out the Duraspark system for an aftermarket ignition system?

I was going to get an MSD, but opted for the DUI distributer. It's a bit bulky, but just one wire which my Centech Harness was made for. It will be nice to eliminate everything else, plus parts for the distributor will be easy and cheap to find.

The reason I switched is I managed to break my distributor while I was trying to take it apart, so thought it would be easier to just buy new aftermarket distributor, rather than hunting around the bone yards or ebay looking for a decent used one. I also was Leary of how long my 31 year old Duraspark control module was going last as well and with my luck it would die on me and leave me stranded out in the middle of no where.

There is a red wire I believe that is coming off your ignition switch. I think that if you take the harness off the ignition you will find it because it says 12V on the switch. From the instructions on my new distributor, you need to connect to a 12V ignition on wire meaing the wire is only energized when you turn the key to on just before cranking. It will keep you from draining the battery or constantly using power when not needed. It would seem you have to run this ignition wire to the red wire on your coil or the + wire.

The best way to hook up a 12v ignition is through a relay fed from the battery and activated by an ignition hot wire. This will get you the full 12v without pulling down other circuits. Also, it's alittle late to tell you but a vacuum advance option would have been good.
