2007 nissan sentra door triggers

i am about to install a viper 1002 into my 07 sentra. on the vehicle data base on this site, the door trigger wire is not really clear. i then found this page... http://www.commandocaralarms.com/wiring/2007-/Nissan/Sentra/1269.html and it says to diode each of the 4 trigger wires. can i just use the dome light illumination wire and still have dome light supervision connected to the same point? do they need to be isolated if i do? thanks.

Yes, and yes!

thanks. i have a few more questions pertaining to this install. i just opened up the kick panel and found 2 wire bundles, one presumably goes up to the door, and the other goes down into the floor. in the door one i found the 2 power door wires, pink and red, but there is a large gauge and small gauge, does it matter which one i tap into? and, i assume, on the lower one i found the door trigger (RED / white) and the parking light wire (RED / blue). if i'm in the right spot and the color matches the database, should i just go for it? is there a way to test it with out striping the insulation? thanks again.

i have to bump this... has any of you installed an alarm in a new sentra? i still can't find a suitable door trigger. i would prefer the dome light, but the red and black wires at the kick (going to the dome light), each always show 12v and ground respectively. i am measuring ground by continuity and 12v with a meter to ground. yet the dome goes off with the door closed. the RED / white wire in the wiring databases always yield ground, but made my continuity checker make a weird nose. can anyone give me some insight? if i don't find it, i will just wire a switch to the alarm input so i can program it.

My info says door trigger should be light blue(-) in the driver's side harness to the rear of the car.C Renner's Auto Electronix

thank you, i guess i have one more wire to test. where was this info? the wiring database here says its RED / white, codesystems says RED / white, commandocaralarms says its RED / white and wiring instructions says red at the bcm (for dome light), and all of them are wrong. i would like one connection for all door trigger, but i would take just one.

dont underestimate scytek because of name. the wiring info is very accurate and reliable.

oh i wont. i just want to find the dang wire before the alarm arrives friday. i also assume that the one lt blue wire will only trigger input for the one door. i suppose i could remove every door trigger switch and look at the wires (to get the color) and tap into those with diodes at the kick panels. i will test it tonight to see. it sure would be easier to do the dome light, but that has been a problem venture since i started it. thanks guys

I would assume that the wire works for all doors - usually they specify if individual door triggers are necessary - it's not hard to test and find out.C Renner's Auto Electronix
