Im having masses of trouble returning my s1 back to using a Ford radio and joystick setup. I have a 4 speaker setup all Ford with the Ford loom, my problem is that a connector has been cutoff to the radio!!!!. The joystick still has its connector, the rear shelf is properly connected and so are the front speakers. i have four wires which must go into the rear of the radio cassette, a red, a brown, a brown/yellow, and a red/yellow. I have tried different combinations and still nothing, also i dont know why i have four wires going to the radio when im sure it needs eight!!!!!!!!!!!!! like 4 + and 4-. The Ford setup is very strange can anyone help????

quick run down
1. all speakers connected correctly
2. loom is fine(apart from where it goes into the radio)
3. radio cassette is a ecu1
4. joystick connected correctly
