There is a good chance that you have already watched at least one of the following Youtube videos.
Both show how to make a repeater by linking two radios (usually Baofengs). But I am having my reservations about the wiring they use.
This one has it DEFINETELY wrong.Set up a Baofeng UV-5R Repeater System
Similarly, Miklor’s site shows the same method in detail.
The reason is explained in the second video, but still I cannot get what he is doing with the wiring.
So let’s take it from the start.
Below is the Kenwood type interface, applicable to most Chinese radios our there (Baofeng and Wouxons for sure).
What we need to use are the MIC +&- and Speaker +&- connections. Watch how the Speaker+ does not reciprocate to the Mic+ pin in a male-male adapter cable.

And here is a better diagram of the connections.
So we got to make a custom cable, which I did from scratch.
Now if you are not up to soldering, there is an easy way to make your custom cable, using these connectors.
Let us know how you did, and if you can understand the wiring on the second video, drop us a line.
