New user registration is now closed. Over the past few years, there have been hundreds of spam registrations per year, with only a handful of legitimate users. Also, the activity level of the forum has dropped off significantly. All signs of a dying community -- and that's OK. At this time, I'm clos...

Hi CHACHY, The BA Amplifier has only 1 pair of stereo inputs, usually driven by the 'rear' output of the new headunit. The fade ( front to rear ) is controlled over the CAN-bus by the factory radio. So, with an aftermarket unit, you'll have no fade control. I'm not familiar with any ability to corre...

Ooh... you could also get a small e-paper display and put it in the kitchen, to display actual % levels (not just 4 segments).

Just ideas to spin your propeller

Nicely done, JimmyM. Some thoughts on other features you may consider -- code this up on an ESP32 (or esp8266) with a small web page and MQTT support. This way, you could always display the tank level on any Web browser, or feed it into home automation or other alerting systems ( Thinking HomeAssist...

FYI -- For any other off-spec things you find, there's probably an entry for it in the rvc-spec.yml file from rvc-proxy project:

Hey JimmyM, congrats on the progress! The 0FECA DGN is an off-spec duplicate of 1FECA which is a diagnostic message ( DM_RV ). Completely safe to ignore.

Hi JimmyM, the Pinout starting from the release clip side is:
Release clip -> (12v) (CAN-Hi) (CAN-Lo) (Gnd)

The cable I use, that produces color pattern:
Release clip -> (Red) (White) (Green) (Black)

Hi JimmyM,
The connector is a 3M 4 pin connector... Here's a link to the item on Mouser:

FYI -- for tank level, that is covered in section 6.28.2 of the PDF starting on page 177:

Also... for my specific use ( turning off my RO water production ), I didn't want to stop at the first sign of 100% full on the Fresh tank. Thus, why I put the counter in place and only turn off the RO when there have been 60 consecutive full readings. This is because the levels are rarely triggered...

Hi JimmyM, Yes, buf[0] == 1 would be the black tank. and == 3 is the Propane level ( if used ) The tank level is provided as a function of how many steps are active, out of how many steps are possible. For example, due to tank height, you may need to cut the sensor down from 20 segments to 18 segmen...

Ya, the RV-C spec provides details on how often each type of message should be broadcast. But since it is broadcast, you simply monitor the CAN-bus for the messages you're interested in, and process as needed. The arduino code show good examples of all that, specifically the tank level readings.

Yep, that's what comes stock on Tiffin Motorhomes. Thus, it's what my code was written for.

Ah, one catch.. Amp bypass, not using the inbuilt amp.

Looks like they have the details -- I added your truck, picked a head unit, and it suggested the extra parts needed for the install.
