86 or 88 xt wiring help needed

[hass]

hey i was wondering if any one out there knows about puting radios in to the xt's. Austin and I would like to put radios in our xt's but some one has hacked the harness in both of our xt's we were wondering if any one has the diagram or if any one has done it and wrote down what wire goes where and what to use for the antena?

 

thanks
