3 days of trial/error still stumped

Hello, all. I don't mean to be that guy that just comes on to post for help and dissappear but here is my first post lol. I plan on paying this forwards because I have not found enough information on my specific vehicle. My electrical Background is pretty null, I've set up my sound system and put in my head unit, replaced alternators etc. but when it comes down to installing an alarm i'm pretty baffled. I'm forcing myself to learn this so that I can do it in the future and be able to diagnose my own problems eventually. (And help others as well.) Before this I knew nothing at all about electronics besides our cars use 12 volt dc and thats what i test for to see if something works. After literally 20 hours of trial and error/ripping my car apart, testing 100 different wires with my multimeter searching on the internet (Most of my searches led here) I've managed only to get my door triggers to work properly using a diode for one of the wires. The part where i'm really baffled is the door lock/unlock. It is a one wire system that requires a negative pulse through 1.5k ohm resistor for unlock and just a negative ground pulse for lock. (Maybe the other way around but ill try both and see which one works) I have a 2002 mazda protege5 and my alarm is a DEI Python 700. Herein lies my problem. From what i've gathered you need 2 relays for this type of one wire system. Well, this alarm has 2 relays built into it (I found this out after i bought the relays) I'm stumped as to how and where to place these wires. I tried a few combinations one of them ended up in SMOKE (Wires burning) and the other one ended up unlocking doors only when i touch the wire to bare metal. Now i know why wires are fused! lol. Surprisingly my unit is still intact. This is where i decided that i need help. Well, the wires on my unit that come out are as follows. WHITE/ black Lock #87a (Normally Closed) Greend/black Lock #30 Common (Output) Violet/Black Lock #87 Normally Open (Input) BROWN / Black Unlock #87a Normally Closed Blue/black Unlock #30 Common (Output) Violet* Unlock #87 Normally open (Input) *The violet and violet black are joined together at a fuse and end up in one wire at the end. Which of these wires am i suppoed to connect where? I've searched and searched on relays and different relay combinations and haven't found out what the (Common) Wire is for. or if im supposed to connect them together. All of the relay searches ive come across just lead me to the types of relays, SPDT and SPST and some other weird crazy ones. i've also already come across the different relay wiring diagrams for wiring to single wire systems but none of them seem to explain where to place my specific type of double relay. IF someone can help id really appreciate it. I've tried my best on my own and am still stuck. I plan on posting what i've learned into a very understandable format that other people who own a similar one wire system and a similar type of alarm can understand. Thank you.

Both common wires to your vehicle one wire. Violet either to ground, or to ground via the 1500 ohm resistor. Violet black gets the other, either ground or ground through the resistor.

Do i put constant 12 volts at any point? or does the alarm power the relays through the 12 volts going through the main harness. Before i looked at your reply I tried a combination of the common wires at the vehicles single wire, with WHITE/ black and BROWN / black grounded, and violet at constant 12 volt. I also put the 1.k resistor on the lock wire. Well, this works! locks the car, but if i try and attatch BOTH wires to the one wire it doesn't go off at all, I'm gussing it's because one of the wires sends a positive pulse which nullifies the negative 1.5k resisted negative pulse that locks the door. So i was thinking that maybe i can get a single relay for the unlock wire to send just a straight ground pulse for unlock. Ill try your method first though before i go into all that other business. I'm going to try your combinatino right now,

Just do as Mr. I says, alternatively purple and PURPLE / black to ground. GREEN/ black via 1.5k resistor, join to blue/black then to vehicle wire. Insulate and don't use WHITE/ black or BROWN / black. Positive supply to the lock relays is internal to the alarm off the red 5amp supply line. P.S. The above should be in your alarm instructions, remember RTFM.

Trust me i went through every page of that manual. It only states that how the wires are correlated to the internal relay. and that it can "Directly interface with most door lock systems drawing 30 amps or less" I appreciate the advice guys. It also has 4 auxillary options which i want to make the windows roll down/up or run something else. I'm considering taking a basic electronics class online or in college so i can really understand the why's and the hows and all i would need to make my car do what i want is some relays, motors and wires.

Those were very quick replies and thanks again.

Just tried this and it works!!!!!! Thanks a LOT. God that's such a huge relief. Now i just have to figure out how to isolate the driver door for progressive unlocking...... ;). another 10 hours here we come.

Trust me you will need 2 x 530t to make all 4 windows close and vent/open and you will need to use your orange ground out (GWA) wire and one aux to control that function. Also trust me in that the only way to learn is hands on and understanding current flow (on DC work), diodes and relays. Reading the diodes and relay section in this site will accomplish a lot.

Hey supern00b - thanks for your thanks, and replying that it works. Alas I keep telling that "idiot" that he isn't (and that I want his name!) and as to Howie - what can I say - is he ever wrong? I've probably just popped in spurred by recent events on this forum... I have nothing of value to add other than nice to read that you get solutions here, and that the advice you get - especially from the above - are probably bang on. (I should say "will be" band on!) Don't reply to this - save it for the confirmation that the 2 x 530t etc works, else related question. Good Luck!

Howie, where did the windows come from?
