Need help!!! Bypassed fader now have strange problems....

[mr_turbodiesel]

Hi,
I recently did away with the becker fader in My 1985 300SD. Now I have the audio I want and the stereo works great.....
But,
Now my number 1 fuse( controls: parking/tail light right, warning buzzer, illumination; license plate, instrument, heater and ventilation controls, switches, electronic radio.) keeps blowing.
I have checked and rechecked dozens of times to no avail.
I am an electrician and am familiar with working on cars but I need help on this one.
Please be descriptive
Thanks
