I wonder why the wiring diagrams didn't get updated?

I wonder why the wiring diagrams didn't get updated?

AFAIK they did.

Not an update as such, but I have the complete wiring schematics for HQ, HJ, HX, HZ & WB all as separate documents. I just checked the HX one & it has the 2-pin switch & associated wiring all there.

I think that the problem is GM-H didn't actually publish factory workshop manuals for HX or HZ, so most just use the HJ manual supplement & fudge from there.
