96 Mercedes C220 Remote Start

I need you help, I installed an ungo 2007 on a 96' Mecedes C220, the problem is it has a factory antitheft system and when locked it will not start, so when the ungo locks the doors to start the car it just burps. I was able to use the wires directly at the vacuum pump and lock/unlock and remote  start, but now once remotely started it will not allow you to use the Dash mounted doorlock switch. I am really stumped on this one, DEI database info said to ground a PURPLE / brown wire at the pump but there is no PURPLE / brown wire? anybody do a remote start on this vehicle, I reaaaally need to get this working correctly.

Thank you

It disarms with the door locks.  So you either need to unlock the doors before remote start or you can send a ground to the PURPLE / blue at the starter kill relay in the drivers kick panel.
