Ungo SR5000 and 04 Dodge Ram Diesel

I am planning on installing this security in a 04 Dodge Ram with factory alarm. The owner wanted this alarm because of its features. I have read some of the post about the vehicle and alarm I understand this Ungo is the same as Valet 551r. I have also read some of the post cocnerning this vehicle. I am just trying to gain as much info about alarm and vehicle to avoid any problems. I actually have the vehicle wiring diagram from one post, but I do have a question concerning dome supoervision. What do the mean by use door trigger wire? I would appreciate a wiring diagram. Here is the link to the old post. Any help is much appreciated. This will be my forth alarm.MEH66

if youre havin trouble findin the trigger, pretend the dome supervision doesnt exist and just use the door trigger as a "input door trigger". ur car should have multiple wire for each door, must isolate each wire you grab. Houston,TX

profuse007,

I am confused by your answer. Could you clarify what you meant? Just for clarity, the question I originally asked was pertaining to the wire diagram I got from another post. I copy it below and bolded the question I was trying to clear up in my mind.

Hey man thanks for the info i did one yesterday and the only problem i had was that i got a wiring diagram from a post i found yesterday and all the wire colors where wrong so i had to find all the wire colors myself it was a **** but the colors you put up are the exact ones i found i put a regular alrm the only problem was the dome light wire. Because you need to diode isolate but other than that i had no problem keep in mind i put a regular alarm not remote start. If read about alot of problems other installers have had with remote start but i think as long as you do everything the way its suppose to be done you should not have any problem just make sure to diode isolate any wires your suppose to and dont pick on any wires your not suppose to.WiredUp
