duh, I'm sorry, I should have waited for the GMOS-01. The instructions on this doesn't require me to fish around for the wires I mentioned above. Instead it acts as a quick connect harness with instructions to connect to the existing factory harness that will have all the necessary wires anyway.
Don't understand the jack plug on the SWI-PS though. Were does this plug into on the 900BT? On the laoction for the wired remote input? If so, then it's too small for the standard 3.5mm jack on the 900BT....thanks in advance.
