1999 olds intrigue remote start?

My father recently bought a used 1999 Olds Intrigue. The ignition lock cylinder got jammed the other day and I went to pull the old one out (dash mounted). When I was taking the panel under the drivers side dash apart I noticed something was spliced into one of the wires leading to the OBD2 connector and taped up. I didn't untape it to see what it was, but I am assuming this may be a key, or a resistor of the keys value for a remote start system. I have a few questions. First, as far as I know he only has the factory keyless entry remotes, so if a remote start was added what is the button sequence used on the old style GM remotes for an add-on remote start? Second, will having this key or resistor in there prevent me from programming the keys that I will get with the new lock cylinder (it has a PASSlock system)? Third, if there is in fact a remote start system, and I try to start the car using it, will the car go into a security lock mode seeing that the new key value that I will have to program will most likely not be same value as the one already installed? Thanks in advance for all suggestions and help.

Get up under the dash and find the brain. There should be a make and model # on it. This will help us determine wether it is a standalone or add on, plus you will know for sure there is even a system still in the vehicle. For all we know, someone could of already pulled the brain. The wire going to the obd is part of the bypass module. Depending on the module installed, once you get the new cylinder in, you might be able to reset and relearn the new code. The model # of the module will help.

Thanks for the reply mikvot. Yes I will get under there and look around for the brain. The car is about an hour away, so I can't get there for probably a few days. One thing that I was just thinking though, is that there wasn't a wire coming from that bundle on the OBD2 harness. It is not like that was a splice point and it ran to a bypass module or a brain. It was just something spliced into one wire on the ODB2 harness and taped up. Whatever it is, it didn't go anywhere. That is why I was thinking a resistor or something for a remote start. Is there a wire on that ODB2 harness under the dash that a resistor of the proper value could be spliced into so that the car would think the key was in the ignition during remote starting?

Related to my other question about the remote start...the 1999 Oldsmobile Intrigue I am working on has a bad ignition lock cylinder. When the cylinder jammed, the drivers side window was down. Being unable to turn the cylinder at all meant that window stayed down. The car is now partially disassembled and I would like to use jumpers from the car battery (which is disconnected) to the window switch at the driver side door to put this window back up. My question is, which wires do I use? I found the vehicle wiring info herehttps://www.the12volt.com/installbay/alarmdetail/1727.html and it shows LEFT FRONT, which I assume is the drivers side, as DARK BLUE. Is this a 12 volt wire? I know that some systems in cars now have constant power and you need to make up the ground side to operate them. Am I looking to put 12V to the DARK BLUE wire to send the drivers side window up? Also, what is the GROUND wire in this system? I will need to jump to the ground wire from the negative post of the battery also, as it is now disconnected from the car. Thanks in advance for any help.

The only wire that would be tapped in at the OBDII plug is a purple wire. There are some bypass modules that connect there (like on your Trailblazer) that bypass the Passlock II. You can not add a resistor at that point to bypass the Passlock II.

Possible ways to activate an add-on remote start using an OEM remote include Lock-lock-lock or lock-unlock-lock.

After you replace the key cylinder you need to teach the car's BCM the new resistor value. I believe you turn the key to the ON position and let it sit until the security light stops flashing. I think its about 15 minutes. I've never done this, just something I've heard through the years.

If you can locate the 2 wires that go to the motor, if you apply 12v to one and ground to the other, the window will move in one direction.  If you reverse the wires the window will move in the other direction.

Thanks for the reply and info JWorm. I am going to have to take a ride by there in the next few days and unwrap that tape and see exactly what is in there. Maybe there was a wire coming from it...I was into disassembling at that point and didn't look at it that closely. As far as programming the car for the new cylinders resistor value, I have read exactly what you describe and have also read a procedure where you try to start the car, wait for the security light to go out, key off and try to start again, repeat 3 times and on the 3rd time it will be learned and the car will start. I will have to try both and see which one works. Thanks again for the info and I will let you know what is inside that electrical tape when I get by there to unwrap it.

Nice answer could all the other newbies posting stupid questions on power windows please note Mr. Idiot's answer.

Understood. I am trying to avoid taking off the door panel by just jumping it at the switch. If anyone has the info I am looking for I would appreciate it.

The 2 wires that go to the motor will be at the switch. 

or jump the plug at the ignition harness and power up the window system ( probably an orange, or brown heavy gauge wire). then you can just use the switch.

I would go with this method too. I think it is the orange wire you will have to give power to. It sounds like you already have the ignition switch unplugged, so this should be easy to do. I believe it is the orange wire you will need to provide power to. You can use either the red or RED / white wire in the ignition plug for power.
