Compustar 2WSS-AS into 98 Cabrio?

Hey guys, I have been on the site a couple times in the last week and this is a really great resource.  Tons of very helpful info and very wise posters.

I have tried searching and have not been able to find specific answers to my questions, maybe you guys can help....

My wife has a 98 VW Cabrio and I am planning on installing said alarm in it while she is out of town, myself.  I have done Stereos and am comfortable with electronics and understand 12 volt power pretty well.  That said, this is the first time I have attempted to install an alarm.  I'm really excited to do the DIY thing, but nervous I don't have all the know how I need.  I have the Haynes Manual for the car and pulled down all the info I could find from this site - I'm just wondering if I missed anything.

A couple of things that are still in the air...  Some of the shops we had talked to mentioned a "factory disable" or something to that effect that needed to be bypassed in some cases.  I don't know if this requires additional hardware or this was the "undercoating" of the alarm world.  I think that they quoted a price of $30-$40, so it cannot be all that complicated.  Also how complicated do things become with a remote start install, nothing was really mentioned on this site about that.  And finally, how difficult will it be to add additional modules later on like proximity, windows, etc.

TIA, I need all the help I can get.

Thanks guys, by isolating do you mean place the diode between the 2 wires?  Isolation is something I am unfamilier with.

Thanks again for the help, anyone else...

Hey guys, I'm in need of some serious help...

I installed the alarm last weekend and everything was working quite well.  The remote start, etc...  Today I was leaving work with the car and tried to remote start it.  Car would not start.  I got in and tried to manually start the car and I get all sorts of activity from the car, but not starting at all.  I have double checked all connections and fuses, I know the tach signal is good.  I have even completely removed the brain from the car and still nothing.  I am completly baffled, especially since the car was working beautifully for nearly a week.  I finally got fed up and push started it, and the car runs like a champ, but still no starter activity.

Great, thanks a lot guys.  I will check into these issues today.  I am aware of the factory alarm module, as this is where I made a lot of my conections.  I may try to un-plug the factory module all together and see if that remedies the situation.

Come to think of it, I did just change an option on the alarm the other day to add lock with ignition, I wonder why the effects were realized a couple of starts later on though...

Once I have located the starter wires of the factory starter kill, should I tap into those with the compustar, or cut them and leave the rest of the module alone?  The factory alarm has not been acting normal however, with the key in the lock the doors will lock but the horn will not sound, I thought I had checked the fuses up above, but will look again.

Thanks again, and if anything else comes to mind, please let me know.

Well, it ended up being a lose plug on the back of the alarm module... I had checked all of my conections but did not check to see if the harnesses were all seated properly.  Thanks a lot guys for all the help and for steering me in the right direction.  Just for the record, my alarm module has three harnesses leading to it, I don't know if this was a design change or not.

Anyway, Thank you all very much.
