I'm installing a Mannix R/S on a 1996 C 280.  My original specs indicated that the car had negative pulse locks, but after removing the driver kick panel I notice the yellow hose and came to the conclusion that it has vacuum locks. 

Does anyone know how to wire this type of system?  lock/unlock wire colors, relays, etc.  Is the vacuum control module in the trunk?  Please advise

Factory Alarm bypass.  My specs indicate that I have to send a ground (-) signal to the PURPLE / green wire to bypass the factory starter kill for R/S.  Where is this wire located? Please advise

Thanks in advance

|       POWER LOCK|black *2            |- |either kick                 |
|     POWER UNLOCK|blue *2             |- |either kick                 |
*2 Operates with normal one second ground pulse. These wires also trigger a factory starter kill on the base model cars w/o alarm system. Ignition controlled locking will cause a no-start problem because of this. The PURPLE / brown wire at the door lock pump located in right rear corner of trunk must be grounded for vehicle to start. There is also a single WHITE/ green wire at the dash mounted door lock switch that does not engage the starter kill. It can be located along the passenger side of the console under carpet. Type E but 1 second pulse will operate. May not operate locks at all times - test before connecting.
this car is a pain as with door locks.My Ex had this crap. i put up with it for a while then just added my own locks.
Look for a WHITE/ green wire at eh dash mount door switch. use 2 relays
lock
85 from alarm
87 ground
87a WHITE/ green wire, the ones that go to the door
86 12v fused
30 goes to unlock relay 87a
unlock
85 form alarm
87 12v fused
86 12v
30 to WHITE/ green to pump.

Notes:
*1 Ignition harness accessible at bottom of fusebox. Pull fusebox up into cowling area to get at wires. Use PURPLE / green to bypass factory starter kill for remote start. *2 Operates with normal one second ground pulse. These wires also trigger a factory starter kill on the base model cars w/o alarm system. Ignition controlled locking will cause a no-start problem because of this. The PURPLE / brown wire at the door lock pump located in right rear corner of trunk must be grounded for vehicle to start. There is also a single WHITE/ green wire at the dash mounted door lock switch that does not engage the starter kill. It can be located along the passenger side of the console under carpet. Type E but 1 second pulse will operate. May not operate locks at all times - test before connecting. *3 Brn/gry at pass. front pin catches both front doors. Brn/gry/yel picks up rear doors. Also found as BROWN / pink at pin.   *4 Factory security module in trunk (if vehicle has one). May isolate arm/disarm from locks by using relay. Windows also controlled by locking and unlocking doors with key (convenience module also in trunk).
