93 240sx problem: locks wont stay locked

[ZiG]

I have just finished installing an alarm I bought, and I am having a problem. The doors will unlock and lock, but they won't STAY unlocked. the alarm I have has a -ve output for lock and unlock, and the car uses a single wire setup. So I set it up according to the diagram I found:



I guess the problem is that when the alarm pulses the signal to unlock the doors (IE ground the wire), the doors will unlock, but then lock again as soon as the pulse is stopped. I'm not bad with electrical stuff, but not great either. I can't figure this out, despite several hours of searching and reading. Is it a bad diode, perhaps? I tested it with my multimeter and it seems fine.. Any other ideas?

TIA.

Oh, by the way, this is a Canadian model, if it makes a difference. It does have stock actuators in both doors.

the way the 180 r 240 lock setup is, it wont do it. It just wont stay unlocked or locked. i ha o disconnect my stuff after consulting an old friend who installs alarms
