RS35 VHF Repair

[slappysalmon]

I am trying to repair a cheap RS35 from ebay I paid $35 for. LCD screen and all other functions check out! I need help slicing a new mic in, I need to match the color wire to its function, ie, PTT, H/L, Ch +, Ch -, Scan, 3Ch, 16g, and ground.

Does anyone know, or have a good idea how to test for these without the mic? Also I will be happy if I can get only PTT wired as everything else is adjustable on the main radio.

Thanks!
