It has now been a few years since I did all the electrical wiring in the truck. At the time I created some wiring diagrams for myself so that I would have a map to follow. While not very complex, it is still a lot to just keep in your head. Anyway, I always intended to post my wiring diagrams in case someone else finds them useful. But I did not ever feel like they were presentable and I wanted to clean them up some before making them public. I never did that and recently someone asked me about my wiring diagrams. So I decided to post what I have.

I have been trying to decide what to do for a connector for the charger. Basically it became a question of J1772 or something else. I chose something else ... Here is what I just purchased:

L6-30 connector set for charging

This is the first of two emergency disconnect features available in the cabin. This first one, the "big red button", will be used to disconnect the coil of one of the contactors.

I was trying to decide where to locate this, thinking I was going to have to cut a …

I have been spending time designing the wiring harness and am at the point where I need to choose some connectors.  For the circuits that are carrying any current, I think I am going to use Anderson Powerpole connectors.  I like these because they are sort of like lego blocks for connectors.  I also like the fact that it is simple selection process, it is clear what you need and what you need to order to get working connectors.  I like this site (powerwerx.com) for the Anderson connectors.

But when it comes to connectors for signal wires, I find that there is a bewildering array of choices.

Even though here in Austin we don't have a lot of days when heat is needed, I think that I do need a functioning heater in the truck.  For one thing, I might need to be able to blow hot air on the windshield if it starts to fog up.

So, I removed the original hot water heater core and modified it by adding an electric ceramic heater element.  Keep reading for the details ...
