www.radiomicwiring.co.uk is a great site for finding out (funnily enough) microphone wiring connections.
For your radio the wiring is as follows:
DX5000 4-pin wiring
The power mic uses a "standard" 6 pin connection as follows:
Standard 6-pin CB mic
Unfortunately I can only provide you this information as is given, I usually wire mics up from schematics or self tracing.
Hope it helps.
