Alarm, e36

Alarm Install Help (e36)I bought an alarm on eBay, that was very very basic and cheap. Mistake #1. I got the alarm today, and started to wire it in. A process that I would have thought was going to be pretty easy, as it had been in the past with other alarms. Not so. I'm having a few problems, some of which are car-user based and some are instruction based.Problem #1: How do I get the hazard's to flash? I know to hook up to the headlamp switch, that part I am clear on. What I am not clear on is where the heck to run the wire to on the alarm brain! As far as I can tell, there is no hazard output. Help?! Also, can I use the hazard wire on the factory alarm plug? Will that work? Less wires running across my car makes me happy :-)Problem #2: Lock/unlock. The biggest problem here is not how to make the car do that (I have found a few DIY's and it *seems* like it should work...) but rather how to make the alarm do it! I have 6 wires for 'central locking' and am supposed to wire it up to work, but the directions are not written in proper English and are quite hard for me to make sense of. What I have figured so far is that I hook up the 'yellow' and 'yellow/black' wires (from the 6-wire lock plug) to a +12v source (fused, for my mental safety and perhaps my car too) because the car uses positive locking. The rest I am confused with, because the alarm brain doesn't seem to output a 12v signal when I either lock or unlock it. Then again I could be wrong here and be wiring it in wrong. I was trying to follow 'Figure three + positive trigger' in my second image.Image #1 - brain install diagram:Image #2 - door lock harness install instructions:One more thing, on the first image (brain), what the heck is the little loop that says Cut off "5S" by it? I made a note in the image too. Any idea?Also, the make and model of alarm are kind of unclear, the box says "CAR ALARM" "HS-100" and "Made in china" (lowercase China? Odd.) I bought it here.If anyone can help that would be very very appreciated. Thanks much!AIM: sigma2kxEmail: sigma666@gmail.com1993 BMW 325is

Problem 1: You want the parking lights to flash, not the hazards. This system has 2 seperate outputs for parking lights, so hook these to the 2 seperate positive parking light wires in your vehicle(they are listed in the wiring diagram linked below). Problem 2: Here is a wiring diagram for your car. Your car lists the doorlocks as being positive trigger for door locking, so you would use figure three. If I am reading the diagram correctly, they are saying to connect the "turn off the signal" wires to your car's door lock triggers and the +12V wires to a fused constant hot. It seems as if you have already done this, so with nothing connected to the car, test the "turn off the signal" outputs to see if they are supplying a + pulse when locking/unlocking. As far as the "cut off 5s" is concerned, If it gives no description of this wire's function, I would leave it alone for now. Wow..."(The first step of preventing the robbenes)" <--Impressive! Hope this helps, Good Luck Keep us posted

Thank you much! #1: Sorrrry, I was really tired last night, and that's what I meant. That is how I tapped them, at the headlamp switch, for each of the separate parking light wires. The problem is what to wire them to on the alarm brain... Help?? #2: It does pulse ~12v, sometimes its a bit weak tho. Thank you for clearing up which one I should be wiring to. I'll give it a shot. Thanks much! If you could lend help as to where to hook up the parking light output, that would be great :)1993 BMW 325is

So the flashers work :) And everything EXCEPT the locks. The alarm signals the locks right even! Well, sort of right - Should it signal positive (+) or negative (-)? And, my alarm lock/unlock wires (WHITE/ red, blue/red) do not do anything when 12v is applied. Or ground for that matter. Help trouble shooting this?1993 BMW 325is

If I have read the diagram for your alarm correctly, your White and WHITE/ Black are your outputs to the factory wires. The Yellow and Yellow/Black wires are the constant +12V fused supply. When you press the lock button on your remote either the white or WHITE/ black will provide +12V output, when you press unlock the opposite wire will provide +12V. As far as your factory door locks not doing anything when you apply +12V to them, they should indeed respond when voltage is applied to the correct wires. Did you read the note listed on the page with your wiring diagram? It is very descriptive on where to grab the wires. Make sure this is the location that you are using. Keep us posted.

Thanks for your reply. I have figured out the alarm wiring just fine thanks to one of my Bimmer friends help, and I have it wired like you said. It works. The car doesn't. Yes, it is tied into my car correctly. The problem is with the car wiring - When 12v is applied to the (WHITE/ red, blue/red) wires in the car factory harness, nothing happens. Where can I go from here to trouble shoot this??1993 BMW 325is

No ideas?1993 BMW 325is

Without having the car and a DMM in front of me, it is a little difficult to figure out why those wires are not behaving as described. DEI lists the door lock wires as being in the factory alarm plug " The alarm plug is a black 12 pin plug located just behind the glove box. It is mounted with the pins facing you atop a vent just to the left of the body computer. ". The cheat sheets are very nice time savers, but if you are not finding what you need using the information they provide, then the time has come to use your DMM and establish exactly how each wire behaves and what it's function is.

I guess you don't understand me, sorry. Let me try again. I know what the factory alarm plug is, and I know how I used to make the car lock/unlock off of the wires in the plug (+ signal to WHITE/ red or blue/red). The problem is that when signal is applied, the car does not respond. I need help trouble shooting the car wiring, and see why the car isn't taking my signal and unlocking the doors. How would I go about finding what relay needs to be replaced, etc? I've gone through all the fuse's, every single one, and they are all good. Is there a secondary fuse box? Help please!1993 BMW 325is
