compustar secondary ignition confusion

Hi Everyone, I have a Compustar CM5000 Module and I've been trying to get my 07 Corolla to remote start with it. I've got the doors to lock okay but not remote start. I believe I am down to one wire that I need to connect. It's the Second Ignition wire. What I don't get is that from all of the wiring diagrams I found, is the ignition wire is +. But on the CM5000 the 2nd Ignition Output is -250mA. Am I suppose to hook those up together? The - & + combination is throwing me off. Also in the wiring diagram that my ebay sell gave me says that I am suppose to hook up the 2nd Ignition Output to a pre-wired relay. I don't have a clue what relay that would be. From what I can tell, when I use the remote start, I think only the radio and the clock comes on. I am not sure if the fans for the blowers come on. Please help. Thanks in advance :)

There should be a relay socket that has 2 wires coming off of the remote start harness and it is a purple and blue wire....The blue should connect to the second ignition wire of the car and the purple is the input wire of the relay in which it needs a negative trigger. The green wire of the alarm/starter which is negative should be connected the purple wire and you are done.

Hmmmm.... so I did that and I still get the same results. No cranking. It clicks on and off 3 times. Should I be hooking up the the other relay yellow/black wire to something?. That is the only wire that isn't hooked up to anything at all on that plug. Any idea on what else it could be?

did you connect the tach wire?it has to be programed for tach.

I'm pretty sure I got the tach. I had to pull up a pin out of the ECM to confirm which wire it was. All of the wire diagrams say its a black wire on the most right side of the ECM. I confirmed that my ECM was upside down :P So now its the most left... So I matched the connectors to my diagram and the tach is on pin 5 which happens to be a black wire :) The only wire that I am really missing is: Door Trigger red   -   front of fuse box, 10 pin plug      Which is also my dome light supervisor. I don't have a clue where that wire is so I left that alone. I shouldn't really need that one right? Any more ideas? This is driving me nutz!

I am installing a similar system in my 99 Grand AM. On the instruction sheet that I have, it shows that you cut the wire that runs from the ignition to the starter in half. Connect the solid yellow wire that is in the middle of the relay, to the starter side, and the yellow wire with a black stripe gets connected to the ignition side of the cut. Does this make sense? I believe this is to prevent you from "grinding" the starter by making it impossible to crank the engine with a key, while the remote start is on.-Jp

Just your average shade tree mechanic.

Did you use any kind of bypass module raginginferno?

From your original post I would have stopped everything there. I mean, can you imagine the damages those big remote starter wires can do to your car if you miswire them. It would be hard to run you through a crash course of why it is so important to distinguish the difference between (-) & (+) or how a relay works when installing a remote starter but seriously... Take a look at the size of some of your car wires at the ignition switch compared to what you have on the remote starter and it should give you an idea on how what you're doing is dangerous.

Also, no one told you you may need an anti grind relay or move your starter wire PIN in the ignition connector to avoid overcranking. And the bypass module, what about it. Yes you need one unless you don't have an immobilizer in your car which I doubt in 07 unless your car is an american model on which the immobilizers are a bit less common.

All of this to tell you. Really sincerely run to your nearest intall center, make sure you're not dealing with a hacker and get the job done safely on your car.

Sorry if my post might be perceived as a blast but here it's a real professional advise. As shocking as it can be.

Please accept my best regards!

If you fail on your first attempt, at least destroy all evidence you tried!

Don't worry it has not ended up as bad as you have possibly described. I do know what I am doing (for the most part anyways). I have an electronics back ground so I do know the difference with + and - voltages and what the gauge of the wire means in terms of current. I actually don't know too much about relays (I learned more about transistors) but I managed to google what I needed to know. So I am not a complete newbie at this. I understand where you are coming from so I did not take offence to what you said. But thank you for concern :) What really threw me off was that I wasn't actually able to find the the install guide for the CM5000 module because the compustar site requires registration before you can actually download. So for a while I was working blind and couldn't figure out how to hook the relay. Now that I have found the guide, everything makes complete sense and probably could have save me a couple of hours of troubleshooting why certain things didn't work. I can't belive how many problems that manual had cleared up! As for my immobilizer, I have the Blade-AL module hood up to my CM5000. It has been program with the correct firmware, and my CM5000 has the older firmware so it already has the rs232 port unlocked and ready to go for the Blade-AL. I had to make sure that the rs232 was set for ADS in option 4-11 I believe. So now my bypass is working correctly. It never blinked the blue light during the crank process until it was in the ADS option. At this point I have finally managed to get my car to remote start. The main thing I had to do was to reset to default all of option 2 before the car actually crank. I must have jumble a bunch of options when fiddling with the remote. I had actually cut off the relay for the anti-grind and had the yellow wire spliced directly into the starter wire. My reasoning for this is if the anti grind relay ever did failed, I might not be able to start my car with my key normally since I would have cut the starter wire. Still one more problem... This goes back to my orginal question really. My 2nd Ignition wire actually still isn't working. My car remote starts but the blower/HVAC doesn't work. This is the wire that controls this and it need the +12V from the CM5000 durning the remote start. I have tested the relay for this and the relay does work. I had purple wire grounded instead of having the green wire hooked up to it, and the blower/HVAC turns on. So why is my green wire that is suppose to be the 2nd Ignition trigger not grounding the relay? If I check the voltage of this green wire, it give me around +150mV. I also checked if it ever goes to ground during the remote start it doesn't. I have also checked 2nd starter and 2nd accessory. They give the same results. So why is this last trigger not working?! Did I program this wrong or something? I actually don't have any of the PC programing tools so I couldn't have fiddled with it that way. I am so close to finishing this! Please more advice! (Sorry for the long response. Just incase anyone in the future finds my post this may help answer a few things. During my google searchs, I found alot of unanswer questions in forums.)

Oh one more thing, this 2nd ignition wire, is kinda of important. If I remote start without this wire providing the +12V when hooked up and then stick the key in and drive off, the airbag light will stay on and doesn't turn off. But if I start it normally the airbag is fine. No complaints there. So I definatly need this wire working!
