Modern Vespa

What 12pin plug is this?

I found it while the bike had the windshield support and front cover removed. Its tucked up behind the glove-box and near the relays. It looks like its supposed to have a cover on it (where did that go?) and a whole lot of pin connections.

I can see what looks like the plug on the electric wiring diagram but this does not have a label for what plugs into it. It must have been like this for years so its not harming the bike or causing problems that I can discern. I'm going to put a proper cover over it next time I have the plastics off to keep grime out.

Looking at the wiring diagram for the MP3 500 series (I hope this is the right PDF) I don't see a 12 pin plug on the PDF. Unless I just have the wrong Pdf which is possible; I have a 2016 MP3 500 Ie Sport NAFTA.

It looks like the plug near the part marked as (3).

It is the socket for the computer/diagnosis/error codes

Thank you! That explains the mystery plug that wasn't on any diagram I could find.

The lack of a protective cover might be the tech doing the inspection forgot to replace it after running diagnostics. No matter, it hasn't been a problem for years and a simple cover should be easy to make.

The mystery socket could be the diagnostics plug, but per later comments it does indeed look closer to the PMP module connector 1st generation.

are you sure, it doesn't look like the diag connector on any other piaggio? and the diag connector would be accessible without removing panels

it does make me think of the alarm connector or PMP or heated accessories ... (but not sure)

Per SteelBytes detective skills, it is almost certainly a PMP first generation connector. The PMP device and abilities look cool but my phone + navigation app (RideWithGPS) already covers what I need.

Its not the heated gear; I have that installed and the connections for those are under the handle bar plastic.

The Alarm is a good guess, looking at the picture the alarm has 16 pins and is much larger while this mystery plug has 12. Looking closely at the picture the white connector block appears to be the right size for a matching 12-pin block and the other 4 pin inputs (to get to 16) might come from other connections.

Unless its the connector for this other model of alarm? I dont have a good picture of the pin connections but it "looks" about the right size.

The PMP2 for the Piaggio has 8 (maybe 10) connections judging by the product pictures.

pmp first gen, not gen 2. it has 12 and is the same colour and shape

Good catch, I wasn't aware there where two generations and that 1st Gen PMP does look right. My Mp3 is the 2016 Mp3 500 Ie Sport NAFTA.

actually there's 3 generations

The android app that I made works with pmp gen 2 and 3 for all piaggio scoots and bikes. I don't expect to add support for gen 1
