When I open up my speaker grill in my headliner, I did not find a small connector.
Ran front/back coax today, drilled small hole as many have described. Thank you all.
I was planning on getting power from the obd port. But I found I have this connector behind the microphone grill.
p85D, VIN 78XXX, delivered april 2015. Small connector as pictured. Looks to me like it may say PA66? Anyone know where I can get the connector to make a short fused power cord? other suggestions?
I have this same connector on my MS built mid-July 2015 (VIN 96XXX). I took my voltmeter to it today and this doesn't appear to have a 12V supply on it. I measured about 10.1V between the black and green wire, but it was not a constant 10.1V. On AC, my meter showed about 250mV of ripple, which I can't really explain. (Maybe my 20-year-old meter is on the fritz?) The 10V was there even when I turned the car off, but because it was a non-standard voltage, I wouldn't feel comfortable running any dash cam from it. There's no telling if even that 10.1V supply would be able to provide any meaningful level of current or what might be affected if you tried.
There was about 300mV between the black and white wires, as well as between the green and white wires. I wonder what Tesla has in mind for this little plug?
Of course, I'd love for somebody to prove me wrong, as I'm hoping to wire up a BlackVue-650 over Labor Day weekend. :wink:
