Finally did my PMGR starter install today on the '79, got sick of the heat soak giving me worries during short shut-off periods such as pumping gas. I've recommended this to many people on here and other forums and have never taken my own advice. Now I really wish I had done this a long time ago, truck starts faster than any of my other much newer vehicles.

Install took about an hour due to rusted bolts and a restrictive work space, in reality this can be done in about 10-15 minutes. The only snag I hit is that it didn't come with a wiring diagram and a lot of the guides online were for the older 3 post starter solenoids and not the 4 post that I have. So I've included a simple diagram below that I have made and verified it to work for these applications.

As far as buying the starter, it was cheaper than a stock replacement and works a billion times better. If you need a starter don't buy a direct replacement, and if you're having any issues its a worthy upgrade for a fair price. No more heat soak issues, more space, lighter, the list of positives goes on. I got mine from Jeff's Bronco Graveyard for about 70.



The quick explanation is that the new starter also has a solenoid attached to it. You'll remove the single thick wire from your old starter and attach it to the new starter's solenoid as shown (red). On your 4-post relay you need to swap the side that it's on (from right side to left side) because it should have constant power. You'll then run a new wire (yellow) from the right side of the 4 post solenoid down to the smallest post on the new starter solenoid. The S and I terminals on the 4 post (the little connections) are to be left as is. When I bought my starter it had a short connecting wire running from the small post to the top large post, that needed to be removed as it isn't used in this application.

Enjoy!
