help with wiring peltors to xts connector

[jonp21]

I have a Peltor Comtac 2 headset that is wired to NATO standard 4 connection plug. I have a motorola xts radio and corrisponding speaker mic PTT. I also have a PTT wired with one end that accepts the nato 4 connection plug and the other end has a 6-pin u-283 connector. I want to replace the u-283 with the xts connector. I have traced all the wires and this is what I have

4 connection plug
| |-headphone ground (blue wire)
| |-Mic Signal (2 wires white and red)
| |-headphone signal (yellow)
|_|-MIc Ground(black)

u-283 6-pin
A-Ground (two wires attached Blue[headphone gnd] and Black[Mic gnd])
B- headset audio (yellow)
C- PTT (Brown)
D- Mic (white)
E- not in use
F- Power (red)

XTS Speaker mic PTT
Black-b+
brown- speaker common
violet- not connected
red- ground
blue- ext mic
orange- PTT
green- not connected
yellow- ext speaker

I need help figuring out which ones need to be wired together, I dont know what B+ is or speaker common, thanks for any help you can provide

Check eBay to see if someone has a ready-made cable. The issue comes in the possible impedance mismatch between the radio and the microphone and speakers.

If you're still determined to roll-your-own, go to Batlabs for pinouts and hints.

there are ready made cables, however they cost about $250 so I know it can be done as I have all the parts they are using, I just want to make sure I connect it correctly, and since there are some different wires in each I am not sure which ones to hook up to what like the speaker common wire

Did you have any luck with this?

Yes. I wired them up but the inner wires are very small so I would suggest soldering them to the circuit board instead of splicing them. The other issue is that peltors use a dynamic mic and the xts radio ptt is an electric mic so the voice output volume is low. The ones I found online have an amplify feature that increases the mic volume. Looks like that is what I'll buy
