I've been given a DEH-P836 but unfortuantly its doesn't have any
manuals or wiring diagrams, so as you can imagine, I'm left with lots
of wires. Does anyone out there have any details which will explain
which wire should be wired to what (It even has 2 wires labeled "Alarm
Sensor" and "Door Lock", whats that all about!)

I understand that it use to be a top notch unit in its day, so I'm
interested to get it going.

Thanks in advance

Paul
