Installing New Starter and Battery Cables, Glow Plug Harness, and Glow Plug Relay
First I installed the AN10 oil cooler adapter fittings onto the oil filter housing. From there I began the rewiring process, where I ran new starter and battery cables, doing my best to tape them up nicely and hang them out of the way.
Next I focused on installing the glow plug relay, originally found on the 7.3 IDI. I chose this version because it is a self timed unit that wouldn’t require a physical on/off switch and seemed to be the most straightforward option for this swap. The installation was simple and the old intake box tray made the perfect space to install this relay neatly. I also cut the makeshift glow plug harness I made and taped that up as well. I will go into more detail on that harness and how I made it at a later time once I am sure that it works properly.
Lastly, I tore into the stock Ford engine harness to clean up, tape off, and cut unneeded connections. This was a simple but time-consuming process. Next episode I will show more on that harness and begin showing which terminals we’re retaining and how I intend to use them.
