    can bus change for 2020?

    You can no longer daisy chain modules onto the diagnostic port on 2020's for some reason -

    They changed part numbers for the add on Depth finder harness for 2020 - which is kinda strange since only 4 wires come out of the depth finder (same one for 2018, 2020) Ground, power in, can hi and low - Old harness will not work - trying to figure out why.

    Waiting to get a new harness (unavailable) 278003852 to see the difference.

    Any insight much appreciated.

    Thanks

    Tim

    That's very interesting, it used to be two modules on the bus had resistors in to stop each signal and it didn't matter how many things were on the system, they must have come up with a diferant way of doing it.

    my guess is that they removed them and now they must be in the module harness or module themselves. If I get the harness I'll know.

    Cheers

    Is that the harness from the Depth sounder to the diagnostic port - or does that go ito your main harness?

    Thanks

    Iím assuming itís from the depth. Itís all taped together and hard to see. I found this tag at the end of my diagnostic port.

    I believe on the GTX the depth is within the main harness - after market plugs into the diag port

    Thanks

    Noticed you have a gauge on fuel system?... ;-0
