I need to find the male plug for this connector

[firehopper]

its used in pride/curtis/quantum power chairs as the charging port/programming port.

Indicating the size of the connector might be helpful. Is it a DIN-sized diameter, or something larger? (I found a few high-current DIN connectors, but with 4 pins max.)

dang it, knew I forgot something, its actually xlr sized.

Hmm, that one is more elusive than I would have thought. I'm afraid my Google-fu is not strong enough -- plenty of military-style hybrid connector but none of them looks quite right. I'll keep my fingers crossed that someone finds this thread who has actually seen those connectors in the wild before!

but yeah apparently its a propitary plug or something, really frustrating to try and find..

I had the same problem with a Pride Quantum Q-logic 3 wheelchair. The connector is an XLR plug with 3 pins (Mainly for audio applications). It has two additional pins with a smaller diameter for the CAN bus interface. The pins are at a non-standard position. I searched the catalogues of known XLR plug suppliers without success - this must be a custom design. In the end, I put together a standard 3-pin XLR plug and two wire ferrules (white, outer diameter 1.5mm) as shown in the pictures. Some patience with a key file and epoxy did the job. The pinout (CAN-H, CAN-L , GND) is also shown in the pictures.

I figured out the CAN messages for the joystick and for the speed of the left and the right wheel (see attached DBC file and two screenshots from MATLAB CAN Explorer). I am interested in any information about other CAN messages or CANopen OD/EDS/DCF of this or similar wheelchairs with Curtis Instruments hardware to help a university project for automated driving functions. It would be great if you could point me to a forum dealing with such topics.
