I am looking for a diagram to show the wires on the 32pin connector going to the radio in order to find the proper wires that come from the steering wheel controls to the radio. The module I have requires I input the specific resistance values (ohms) into the module program in order to flash it for the vehicle.

Resistance in all connection wiring is less than .5 ohms. here is a guide to help with the test and I have included the wiring diagrams so you can see what's going on. Chances are the spiral wire behind the steering wheel has gone out which is common.
