Jeff,

Looks correct to me; wire 233 provides ignition power to numerous locations.

Thank you Jim,

If I am reading these drawings correctly (and I’m not very good at it) the diagnostic power pin C is getting power from the water temperature gauge via pin 3 of the C53 12 pin connector. So if my chassis service bay water temp gauge is working then I should
have power to pin C unless that cable is broken?

Is it likely that my coach has no diagnostic port under the dash?
If I should have a port any tips for finding it? I know it’s not a small thing and isn’t easily missed with a careful search.

IMO It is possible, (but NOT likely), that your coach has no diagnostic port under the dash.

In my '96 Sahara 3530 that diagnostic port is hanging loosely up under the dash ...near the steering column...on the bundle of 4 wires, (1+, 1 - and 2 data), with which it works.

It measures approximately 1-1/4 inch by 1-1/4 inch)...and looks very much like the one in this picture: https://tinyurl.com/s546kd2

Mel,

Please don't take offense, but do you realize that you replied to a post that is two days shy or being a year old???

This section is all from the old group and from what the Admin mentioned are for reference only, meaning that are archives and are too old to reply to anyway...

No offense taken.
I reply to posts soon after I receive and read them.
(I believe I first saw Jeff Jordan's "99 Sahara diagnostic port" question on Jan 17, 2020, and I did not notice the Jan 2019 date).

That said, this "diagnostic port" information:
"In my '96 Sahara 3530 that diagnostic port is hanging loosely up under the dash ...near the steering column...on the bundle of 4 wires, (1+, 1 - and 2 data), with which it works.
