How to wire a 4 pin ProComm microphone to work on a 5 pin microphone for a Uniden Grant XL

The simplest way is to order a microphone adapter from ebay or a reputable CB shop. I have all my mics wired for standard 4 pin cobra. The standard 4 pin cobra is the most common and if you keep adapters handy then you can use all different kinds of mics on different radios.

Does Motoroloa make a mic with controls in the head for the MCS2000?

It's very unusual to find a commercial radio with channel buttons on the microphone, however, with a bit of ingenuity, you should be able to do this. You need to connect two additional wires to the mic connector on the radio and replace the microphone with one that has the buttons. Connect each od these wires to the UP and DOWN buttons on the front panel. You will have to locate two pins on the mic connector that aren't being used. Usually there are a few available. You may have to disconnect two that are being used for the programming function if you don't have any available. This will have to be changed back to the programming function if you want to program the radio again. Connect the two wires in the microphone head to the up and down switches, and there you go. The other pin on the switches most likely connect to ground. You may have to get another mic cord if the one on your present microphone doesn't have any spares.

I disconnected and reconnected the cobra 29 nw ltd classic and now my voice is heard very low and slow it was working fine just before disconnection. can you help

How did you disconnect it?? Antenna wire?? Power supply?? Microphone?? May be that you have a short in your coax in back of radio. Try taking it loose and screw it back in. Try new coax. Turn up Mic gain knob or change microphone. Make sure power wires are connected RED to RED(+) and Black to Black(-). Try grounding radio to metal ; if inside house ground to metal water pipes, filing cabinet, breaker box or meter box or 8 foot rod into earth. Measure SWR it should read 1.1 to 1.5. Measure power supply with Voltmeter it should be 12 to 15 volts. Check antenna plug in back of radio is my guess or microphone itself.
