On the installation page of the guide, there is a nice table for the UTD OBD plug pinout and the UTH 24 pin connector.
I think the J5 26 pin connector should have the same kind of pinout table on that page. Currently, some of the pins are shown on the 12V IO page, but not all. Adding another pinout table to the installation page would be a lot clearer.
It would also be nice if the Pin Mapping page had a column for connector pins. On some of them currently have note for the J5 pin they use. Having all of them listed and doing the same for the 24 pin/ODB plug would make for a complete cross reference.
I would be willing to help make these changes, but I’m a little confused about every pin and don’t want to put bad information out there.
