compustar 2W900FM-AS

I have 2 new questions about this alarm. First question has to do with the antenna. It's rather large and suggested that it be placed in the upper left side of the windshield horazontally. Well I have a 68 bug and the window isn't that big plus I have rarely ever seen any car with the antanna run across the windshield. Is there another place I can put it?

Second question, I recieved the automatic version of the brain. There is no wire inside for manual. Is there a way to trick the brain into thinking i have an automatic? I know this isn't considered safe but I always apply my E-brake for safety anyway. I just want to use the start option but not sure how since i have the auto only brain. I was under the impression that I would have the option...guess I was wrong.

THird and last question, the alarm came with a ...pogo stick? connection. It looks similar to a door pin switch. There is a plastic head on it and at the other end a connection. No wires are pre soldered and there is no referance to it in the manual. Any one know what this is?

3)Hood pin switch?

ahh thats what that is for..ok cool thanks for the reply :)

While i am on the subject and not really wanting to start a new thread, I noticed while testing my alarm that if i have the window down and arm the alarm, i can pull the lock to unlock the door and the alarm doesn't notice. is this normal or do I have something wired wrong?

Also, for the door trigger, the alarm has a - lead and pos lead, do I hook both up or one over the other?

i am new to installing alarms but I will kick in the knowledge I have garnered installing the 2wssr cm3000a brain.

door triggers are EITHER (-) or (+)

No, the alarm will not notice lock position, it only sends a pulse to either lock or unlock. So if lock and unlock work when you arm and disarm, its good to go.

Antenna wire should be long enough to make it the rear side glass, no ? My understanding would be that it is designed to be right up against the glass with lots of exposure for max range. I hotglued mine to the rear door post so it sticks back across the top of the rear passenger window. Doesnt look bad and my 3 yr old cant reach it from her car seat :)

Eccks, I have both door trigger wires hooked up. One on the neg and one on the pos. It's working though....will this mess things up if i leave it this way?

Anyway to get the alarm to notice when the door unlocks? I suppose since the door triggers work I really don't need it to know the door unlocked but it's another safety feature in my eyes.

I wish the antenna was long enough to reach the side window. Unfortunately it's not. I doubt I could find an extension huh? I could drill a new whole for the wire to run threw though but I really hate to drill any more holes then needed.

Personal experiences have proven that if you have the tinted visor it will actually interfere with the signal. i recommend placing it directly behind the rear view mirror vertically.

If you can't Dodge it, Ram it. If you can't do that, blow it up.

The alarm won't detect if you have the door locked or unlocked. It will only detect if the door is open or closed, so your good to go with that. Also compustars ready for manual cars, it has a safety feature where when you take the key out the car will keep running as long as the hand brake is up and the brake isn't pushed. When you get out of the car it automatically turns off and the alarm arms. You have to do this every time to remote start the car. There is a small yellow jumper wire in the brain which you're supposed to cut when it is in an automatic car and what this does is pretty much jus removes that feature because its not needed for an automatic car. As for connecting the positive and negative door trigger leads, exactly what did you hook the positive one up to?

oh ya, one more thing. The hood pin switch is needed on any remote starter. It works just like a door pin switch (-) lead. Drill a hole somewhere under your hood so that the switch is surrounded by metal and will be pushed down by the hood when its closed. Run the grey wire ( it think, it will be refered to as hood switch in the manual) through the firewall of the car and crimp it to the little connecter that comes with the switch and hook it to the switch. Thats it. Good to go. The alarm/starter will work without it but i suggest you put it in for 2 reasons; safety and so that if someone pops your hood the alarm goes off, so extra protection

I'm looking at my cm3000 wiring diagram now, it may look very similar to yours.

Lets make sure we're on the same page, there is door sense (+) and (-) on CN3. Thats exactly what it is, sense the door open or closed. You only use one + or -, in my case 1995 GM B-body, it is (-) sense i.e. if you hold a vom from ground to the chassis wire voltage will go low when door opened (if I recall correctly).

I wouldnt want both door senses hooked up, I'm constantly worried everytime I make a step with my installation that I'll fry the brain, cause its unwarranted.

I dont see why you cant extend the antenna wire, it doesnt appear to be specially shielded. You might wanna do some searches on that though.

Thanks guys, the version of the brain I have is auto only, there is no wire there at all so it's stuck in auto mode. No big deal really as bugs are hard to auto start because of the choke.

It's a 68 bug, there isn't a tinted area on the window so I am ok as far az that goes. It's just that the damn antenna is so big when applied to a bug window lol. I might try and re run the wire so I can get it to the back window.

The door trigger needed some sort of power source. I don't have a dome light so the door triggers were not working. I was going to use a relay and realized I have one on the alarm not being used. It's the second relay that comes off of the main wire harness. It's used for 2nd acc, 2nd ign and something else. There is a violet wire and a blue wire. I have the neg wire hooked to violet and blue hooked to pos. The door triggers work this way so....thats how I left it. If i only should use one wire I'll disconnect one of them.

As for the hood switch, I plan to hook that up. Had to find out what it was first and now find a good place to bolt it in. Thanks again guys for the help.

I am a retard. I was thinking that in order for the door triggers to work they had to have some sort of power source to them. They do after all connect to the dome light which I am missing. After a liitle reasonable thinking, I realized that there is no power source required and i just needed to hook the wire from the door trigger to the neg wire on the alarm. Works..heh ... I am sure most of you are thinking duh....ya..took me a bit.

I have to tell ya, I love this alarm. It's nice to have an older car and feel somewhat like you have new tech in it. I've got power locks and enabled the ability to lock when you start the vehicle and unlock when you turn off the ignition. Everything works. I even got the hood switch installed and working..This was my first alarm install ever and normally I would have shyed away from something like this..and probably would have on a newer vehicle , but over all simple to install. I'm stoked and I have to thank those on here that responded to my questions and gave assistance. Thanks guys!

I share the same feeling.  I just got my 2W900FM-AS installed in my del Sol last weekend.  I love all the features and the remote start is really cool (even though my A/C is out so there is no reason to remote start right now, I do it occaisionally anyways).  I agree that the wiring wasn't bad at all, it just took me forever because I located the brain in an unusual location and every wire had to be lengthened.  I soldered all my connections.  I love the added security of knowing if my alarm has been triggered.  I sleep with my keychain by my bed now!  I also give thanks to all who helped on here.

Remote start is the only thing I don't have functioning only because it really is useless on my older bug. You have to hit the gas to prime the choke..besides I have to let the dogs out in the morning anyway so I just start it up then.

I sleep with the remote by my bed too but last night was proof it's not always good lol. My neighbors dog got out at 1 am and ran past the car. We think his tail slapped the side or maybe he ran into it no one knows but long story short the alarm went off. 1 Am is NOT a good time lol.

I just got the compustar 2wssas installed and it is definitely 'le t1ts'. my remote battery is down to two bars and range has been diminished, but overall my impressions are very good.

I didn't go with the 2WSS-AS because I heard there is alot of lag time between the alarm and the remote plus the 2W900 FM was cheaper and it's remote looked cooler If your using the battery that came with the remote swap it out with a duracell or everready. Them cheap batteries they send with remotes suck and die fast.

I see no lag time w the 2wss. so far, only once did teh brain not respond to teh remote, it could have been from me pucshing too many buttons in sequence. 15-30 seconds later it was responding fine.

the fm remote looks cool though. the 2wss range is stupendous and I havent tweaked the antenna location, minimum 4-6 city blocks around big buildings.

Ya I am embarrassed to say I picked the 2W900FM for the remote It looks so much better hehe. I have not tested the range of mine to much yet. I know where it won't work though lol.
