Chevrolet Corsica - Black Box Under Column?
I have a short and a horn problem on a 1994 Chevrolet Corsica. We traced the horn problem. The prior owner spliced into the horn wire underneath the dash to attach a grey wire from a plug. This plug goes to a unknown box underneath the dash. The question now is what is this black box? It looks like a add on part, since the wires underneath the dash are cut (yellow, orange, red, ect) and tied into the plug which goes to this box. Any help would be appreciated.
