I'm installing an Ungo SR9000 R/S system in the vehicle listed in the topic. Right now I'm stuck at the door triggers. On directwire it lists : Left Front Door Trigger dk. blue and BLACK/ orange driver door module in door.

I've found a wire but while i'm measurin it closed it shows .09V and when any door is opened it shoots up to 12V then back down to .09V and rests there while door is still open. Do i have the correct wire ? I've never seen a door trigger show voltage like this. Any would be greatly appreciated. No other wires listed for any other doors except ones listed

Are you trying to get these wires and use them for door triggers for security, or are you trying to do dome supervision? im not familiar with the unit you are installing.

i'm tryin to use them for security instant trigger input. Dome supervision is the same wire as trigger.

It should be pretty much the same as the Clifford 50.5x

Sorry about reposting your wire diagram. That really sucks because i ran my trigger into the door already lol. Alright I see it has a note as far as the trigger goes. Is it important enough for me to know ? Also, I hid my brain very well behind my cluster in the dash and it'll be a pain to get to. Is there a way I can wire up a relay so that when the underdash light shoots 12v it will trigger the negative input ? If not I'll put in my work for another day

Thanks once again I'm an idiot. I'd like to get more of your help before I get back to working on my vehicle tomorrow morning

Sorry about forgetting the note. It reads as follows YOU MUST DIODE ISOLATE BOTH TRIGGERS TO MONITOR ALL DOORS. However I have no idea what they are talking about "both triggers" . I would assume that you do need the disarm wire. When I quit installing, the only car with a factory alarm was the 300ZX, oh and the Maxima.

I have finished my alarm/RS start system but, I have one more issue. Everything was working fine until I arrived home and armed my alarm. Every 30 mins. My alarm would go off displayin my trunk has been tampered with but it hasn't. Wire diagram showed WHITE/ violet at the LCM and it was hooked up to the Blue Trunk trigger input wire from the alarm. It has acted this way for 2 hours untill I disconnected it from the alarm so not to disturb the neighbors. What could cause this and how can i fix it ? Do I need diodes or something ? It had no notes
