Usb cable

[Ottdurr]

M35 stagea vq25det. I Just discovered a long usb cable with a female end that starts under the passenger seat and traces under the carpet to the passenger footwell and disappears into the bottom of the firewall. Anyone have any idea what it's for?

Current or former aftermarket ecu?

[Ottdurr]

Maybe? I don't know, only owned the car for a few months and the previous owner knew practically nothing about it but It hasn't got many modifications just an aftermarket intercooler and some cosmetic stuff so not sure why it would have some fancy ecu. How would I go about finding out what it has?

Not sure C34 ecu is in LH kick panel but M35 may be behind glovebox. Google for instructions on how to get access.

Probably goes around to the Consult port, no?

I had a mysterious USB cable when I bought mine, turned out that it wasn't plugged into anything, and even though the factory Bose was still in it, guessing the previous owner may have had a USA SPEC PA15-NIS or similar audio interface due to the broken CD stacker and took it out before selling, maybe ...perhaps just an extension to charge devices?
