Welcome Dallas!
Glad it's working for you now.
The 300/4.9 I-6 is an incredibly tough and reliable engine that used to be found in all kinds of things in addition to pickups.
Pumps, gensets, wood chippers......
We don't see too many utility bodies/service trucks here on the forum but hopefully can answer whatever electrical questions you have if you start a new topic down in the main section where more people will see it.
