I've searched the forum but it seems everyone is using everything but the mirror cord to mirrortap their radar detectors.

Most other cars have color coded cables but the rx330 i have, has its mirror cord in black, black and black. there are numbers on the plug ports (1-6) and unfortunately i don't have a voltmeter to check which one is ground and which one is power.

Has anybody done the tap using just the mirror cable dongle or could anyone with a voltmeter give me which offset (1-6) is ground and which one is power.

Thanking You in Advance.

If you don't have a voltmeter (or continuity tester), you should not be tapping into any of the circuits in a car.
Get one now so you can do these neat things with some assurance that they are being done right the first time.
