Compustar 2WFM8000AS

I will start by saying I am feeling almost a bit overwhelmed here. I have installed several DEI alarms, mostly viper, and thought that this would be easy when I purchased this alarm for my 87 VW Jetta.

Im afraid I may be in a bit over my head, but Im hoping some of the fine people from this site can help me out. Please be patient, I am not a real installer, but am trying to learn a little bit.

On the CN1 plug, what is the difference between the Starter Kill/Anti Grind violet colored wire in slot 5 and the Yellow starter wire in slot 6?

On the CN2 plug, what are all of the outputs for?  Looking at it, I am kind of dumbfounded as to what all of the outputs are for when half of them are the same as the CN1 harness.

On the CN3 harness, do I need all of those sensors? I can see the Ebrake and Door settings being kind of important, but positive and negative door triggers?

On the CN5 harness, what do the rearm and disarm wires do?

Do I need to hook up the temp sensor to anything? (plug CN10)

What do I need to do with the tach switch?

sorry for bombarding you all with these simple questions, any help is welcome.

thank you

The starter Kill & Anti Grind are the same thing on the system. The way the system works is that the relay separates the motor side from the switch side during remote start and does not reconnect them until the brake in pressed so that you can not grind the starter when taking over the car. At the same time if the car is broken into the relay is activated and yiou can not start the vehicle until the system gets a signal to deactivate the relay.  The YELLOW wire is motor side & the YELLOW/BLACK wire is switch side for the relay. The PURPLE wire is your (-) when armed wire.

CN2 harness output wires are for 2nd function wires such as 2nd IGN , 2nd ACC or 2nd STARTER . If your vehicle requires any of these you can attach it to the second relay that is attached on your CN1 harness and attach the BLUE wire on that relay to the 2nd function of your choice. If you have a vehicle that requires more than one 2nd function you will use the CN2 output wire and wire in another relay on top of the other relay that is attached to the CN1 harness.

All vehicles only have one type of door triiger outputs, you have find out which one your vehicle has and use only one of the inputs. The emergency brake is only needed if your installing into a manual transmission vehicle, otherwise you do not need to make this connection.

The re-arm & disarm wires are for the OEM security system. If the vehicle has these two wires you can control the OEM system to work simutaneously witht he Compustar system. The DISARM wire is necessary for remote start purposes but the REARM is not.

If you have a temp sensor ( optional ) then hook it up. All the factory 8000 systems that I sell do not have the temp sensor option. If you bought the optional temp sensor, then plug in the temp sensor and mount it somewhere in the center console by the passengerside & driverside.

Leave it alone. If your using a tach signal leave it on 1 and if your using an alternator signal then change it to 2.

OK. Sorry for being slow here, lol. Your response was awesome man, thank you. The only thing I think Im not really sure on is the violet wire. If what Im thinking is correct that wire would be the equivalent of the orange wire in the Viper series alarms correct? But where would I hook that up? these prewired relays confuse this whole process for me.

and the other thing was the tach switch. ts a tach learn switch. there are no settings, its just a momentary button. Should I just leave it alone still?

thanks again for your input Velocity.

oh, one other thing while Ive got your attention, hehe. I have been trying for all too long now to figure out the doorlocks on this car. they are pneumatic, they run off of an air pump in the trunk. They are positive trigger doorlocks, but no matter what trigger I send them, they always reset to whatever position they are in to start with. if you push the drivers lock down, they all go down. When I give the pump 12V, they unlock momentarily, but then reset to lock right away. And if you pull the drivers lock up, they all come up, but when I send the 12V signal to the other side of the pump, they all lock momentarily and then all return to the unlocked position. Im kinda scratching my head here lol.

the car again is an 87 VW Jetta if its relevant.

It's already prewired. All you have to do is cut the starter wire and wire in the motor side & the switch side to the relay.

When you have the tach wire connected and the vehicle running, press the tach learn button.

Before you ask any more questions please read the install manual. All these questions that your asking is described in the manual.

Add an actuator in the door to operate the keyless entry from the COmpustar unit. This is the only way that you can do this according to all my installation notes.

sorry Velocity, my alarm didnt come with the detailed wiring guide, I was trying to make do without. All I got was the user manual for the remote and the Installation Guide. I guess I will go to their website and look for the wiring guide.

Thanks for your patience.

this alarm is not my friend. I am not sure what Ive done wrong, but something is amiss here.

This is what I have connected, and the only thing the alarm will do right now is tell me that the tach wire is wrong:

CN1

Red - 12V+

GREEN / WHITE - Light Switch

RED / White - 12V+

White - Accessory wire at IGN switch

Violet - Prewired Relay

Yellow - Prewired relay, Black stripe to switch, solid yellow to starter

Green - to IGN at IGN switch

Black - ground

CN2 - not used at all

CN3

Light Blue - Parking brake, negative trigger

Gray/Black - Hoodpin, negative trigger

Light Blue/White - not yet connected, but to positive wire during brake engagement

RED / White - doorpins, negative trigger

Yellow/Black - the wrong tach wre in the cluster. would it be a problem in a manual transmission to wire this with the alternator configuration? I spent over an hour trying to figure out the tach wire, but somewhere between the coil and the tach itself, there is a problem.

CN4

Blue - positive lock at doorlock relay

Blue/Black - positive unlock at doorlock relay

CN5

Brown - siren ( the only other thing that works :( )

do you have to program the remotes to the brain with each new install? Im at a total loss here, this alarm is kicking my ass. I probably should have bought the 791, I find the Viper alarms alot easier to install.

any help would be appreciated. are there any wires that need to be hooked up that I missed? I cant even get into programming mode, so perhaps the wiring diagrams I got for my car are wrong :/ I think Im going to have to spend some time in there with my multimeter today.

thank you in advance for any input
