7.3L IDI Glow Plug Relay System Testing Procedure

The Glow plug system is a different beast on the 7.3L IDI. So I made a recent video on how to test it and what all these extra wires are compared to the newer 7.3L Powerstroke engines. I hope this helps as information on the early 7.3L engines can be scarce at best.
