I've got a few questions about an alarm install. The alarm: K9 Sombra

First, I have two door inputs ( + and - ) and they are pin switches according to my manual.

I'm looking at this tutorial:
http://www.yoursciontc.com/forums/in...showtopic=2908

It states that:
I'm not exactly sure what this means, or how / where to connect these two door wires.



Second Question:
I think the tC uses a "Negative or Positive System", more specifically, the negative system. So i have six output wires from the alarm brain, three for unlock, three for lock.
Because I have a negative system, I only need to use two wires for lock, and two for unlock. One of each is wired to 12v+ constant, and the other two are tapped into the correct wires in the driver and passenger kick panels.

Is this all correct so far?

AND,

according the the12volt.com,
http://www.the12volt.com/installbay/....asp~TID~53560

the two are located:
I count pins starting at the top left, correct? And find them from there? And wire these two to the two remaining wires?


Thanks!
Brett

i would tell you about it cause that's what i do but it gets confusing when your not working on the car at the moment and have all these different instrutions

 

you also have a starter, ignition, horn, parking lights, and those inputs are your arming and disarming, then the other 2 are the lock and unlock.

 

here the cables with theirs colors and what they are. there might be more cause of the systems i use but you should be able to get the cables you need from this.

Thanks for the tips. I'm going to go out and try starting in the next few hours, and i'll post back with questions / updates.


Thanks again,
Brett

 

I can't find the door inputs! They should be negative triggered, so I put my multimeter red lead into a 12v constant, and touch the black lead to all of the oranges i see while my driver door is open, but i get nothing.

Which orange wire is the driver door input?




...or the bottom one not shown on the pic?
...or is it none of these?


Thanks,
Brett

 

In Plug #4 pictured above, that orange w/ silver stripes goes from 10.5v when the door is open to 12v when the door is closed, i assumed it would be varying from 0 to 12v.

I also can't find the driver (blue) door input, so any help would be great.

it could be any orange wire there, i don't remember mine too well cause it was over a year ago and haven't done another tc since then. but test all the orange and close the door and if you get a positive then that's your door input. i'll check mine over in abit and let you know where each wire was and which colors they are. i install factory systems so the one you got might have more or less wires but we'll see.

 

Take it to a professional before you fry something. It is not going to be Plug one or 2, those are coming from the door, most likely its going to be number 4. Another easier way to find that orange is go to the sill plate, open that wire loom and find it there. If you test it, with the door open it should read 0 volts, door closed 12v, so it would be a negative system. With the locks, you need to use the 2 wires connected to the door cylinder, do not use the switch wires, or you will not be able to unlock since when the computer turns off it locks out the unlock switch so no one can reach in to unlock the door via the switch. Also when unlocking it requires a double pulse to unlock the entire car, first pulse unlocks the drivers door, second pulse all other doors. Also don't forget to get a Transponder bypass module for your key, otherwise the vehicle will not start with no transponder signal.

Any other questions? 10 years in the remote start biz!!

 

true on taking it to a professional cause you'll fry the fuses which are easy fixures but then you gotta know how to program the system correctly or else it's gonna be going off. i mean they might charge you about $150 installation but they'll be responsible if anything goes wrong. your using t-taps right?

 

for 10 years i have never used t-taps, i don't like them, will never use them ever, all my electrical in my car is striped and wrapped then crimped then taped. T-taps to me are a big no-no, but that is my own opinion

 

eh the company gives them to us so can't let them go to waste LOL but i know what you mean by wrapping the wires together

 

Right now, i'm still planning on using my stock key fob to start the engine, so bypassing the transponder shouldn't be an issue.

I had the negative door inputs backwards, i thought they'd be 12v when the door was open -- that may be why i couldn't find it. I'll go look again now.

Thanks,
Brett

 

Just tried again, and still can't find it! This is very frustrating. When the door is closed, does the orange wire touch ground or positive 12v?

^^ dude careful with the install, there's a lot of wiring with alarm installation, even professionals take sometime figuring out (unless they know the vehicle). Alarm systems are also diffrent so a professional installer maybe will have problem figuring out unless they have their hands on your alarm. And as adviced take it to professional, if they mess up, they fix it.. If you mess up, you'll be in more mess.. But a rule of thumb, dont do anything stupid.. Good luck and have fun.

 

i hope you bought the right module for that remote start cause those are really tricky. if your car is stick then even worst.
