[urq] misc wiring issues.

[Jim Haseltine]

Many (6) years ago I had a similar question:

>> I'm gradually dimantling my 81 Ur-q in preparation for a major
>> restoration/rebuild.
>> I got around to the PS & hydralics yesterday. Disconnected the multi-plug 
>> on
>> the pressure switch on the side of the bomb, but when I removed the bomb
>> from the car I found another pressure switch on the underside - no 
>> multiplug
>> or cables attached and judging by the state of the terminals there hasn't
>> been anything on there for a long time. Should there be connections to 
>> this
>> switch and if so where are they because I cant find any spare wires.
