My SC has the "remote" that amounts to a small control on the end of a long wire. The wire is supposed to come from the unit and pass through the center console. My question is, where does this remote connect into the unit itself? The PO disconnected the control and I have tried inserting this plug end of the wire in nearly every hole you can imagine and maybe a few you would rather not imagine.

Do any of you folks have this older set-up? If so, I'd appreciate a photo showing where the control should plug into the unit. Thanks!
