Help with Viper Alarm install please. Check my wiring

[bmbarnum]

Hello everyone,
I am attempting to install a Viper 5901 alarm system into my 1990 bmw 325i e30; however, the wiring looks a bit more complicated compared to the research I have done through forums here on R3v and e30tech where other members have installed their own alarm system and posted their wiring install process. Now, this is my first attempt at an alarm system and I do not wish to have it installed by a professional because I do feel confident in myself that I can install it myself with the help of the community here. Also, I definitely would love to learn.

Below, I have provided the wire harness of the alarm and it's function and where I believe it connects to in the car behind the drivers kick panel. I will be installing my alarm behind my cluster and zip tied to the orange box which is the SRS module I believe?

I think the reason I feel intimidated by the install is because all of the wires, but I am sure nearly half of it is even needed. I can be wrong though.

I am looking to have the following functional:
- keyless remote unlock/lock door entry
- remote unlock/lock pop open trunk (i believe i'll need an actuator for this)
- Remote start (Car is currently automatic; however, I will be converting it to 5 speed next weekend which is when I will be installing this alarm as well during that process.)


I would really appreciate any kind of help to guide me into completing the installment. I hope this thread also helps those looking to learn how to install alarms into their e30 that looks as intimidating as mines with all these wires.

Lots of question marks here. I bet you could have answered most of these by reading the installation manual from DEI, which is fantastic. But here are my suggestions...

1. RED/WHITE (-) 200mA trunk release output --> Your new trunk solenoid should have fused power according to install manual recommendations. This output drives the negative wire of the trunk solenoid so it opens up. 200ma should be enough, if not, you will need to use a relay.
4. WHITE/BROWN light flash isolation wire - PIN 87a of onboard relay --> If your parking lights do not work, try sending 12 volts to this wire. It might not be needed. Check manual diagram for this.
7. BLUE (-) trunk pin / instant trigger input --> instant trigger for alarm, connect to trunk light. This will make alarm trip when someone pry's the trunk open.
8. GREEN (-) door trigger input --> Connect to door pin switch. Double check both the passenger and drivers door trigger this wire. If not connected, someone can open your doors without alarm triggering.
1. PINK(+) ignition 1 input/output --> Connect the ignition source.
4. VIOLET(+) starter output (car side of starter kill) --> Cut starter cable in half at ignition switch. This side connects to starter side.
5. GREEN(+) starter input (key side of starter kill) --> This is the other side of starter cables you cut, to tell if this is the right side, try to start the car with the wire cut. The key side will show 12 volts during cranking, the starter side will not show any voltage because its cut.
6.RED(+) fused (30a) ignition 1 input --> connect to ignition source.
7.PINK/WHITE(+) Ignition 2/ flex relay output --> not needed.
8. PINK/BLACK(+) flex relay input 87a keyside (if required) of Flex relay --> dont think you need this, double check manual. You might need it.
9. RED/BLACK(+) fused (30a) accessory/starter input --> connect to accessory source at ignition switch.
1. BLACK/WHITE (-)neutral safety switch input --> This wire must have a ground connection to enable remote starter. Use a toggle switch with other side connected to ground to enable/disable remote start. Or connect to Ebrake if ebrake uses negative trigger. If it uses positive trigger, use relay to reverse polarity.
2. VIOLET/WHITE TACHOMETER INPUT WIRE --> You need tach input so the remote start knows the car is running. it can be found at diagnostic connector, cluster, or ECM. The color is solid black. Its in the blue connector behind cluster, easier to grab it there.
3. BROWN (+) brake shutdown input wire. Connect to wire that shows 12 volts when brake pedal is pressed, should be easy to find.
4. GRAY N/O or N/C (-) HOOD pin switch input. Connect to a hood pin switch or install one. This triggers alarm is someone prys your hood open.

Good luck.

Is there a nice point to grab the switched ground for the doors from? or do you need to take it from the relay point? i remember when looking at the ETM it was going to be a pain to grab both door switches
