viper 4103 remote start, ’89 535i

i hooked up the remote start harness, the ground, the tach, the antenna, and the door locks. the door locks work (had to get a relay for it but it wasn't a big deal to wire it). the problem im having is that the when i press the button for the remote start it wont turn the car over. it wont even start the accy. there is another harness called the satellite harness but it's just for when you put the key in the ingnition i think. and if it's not how do i hook it up because that is the only other harness besides the kill switch that i havented installed.

im installing this in an '89 535i. what am i missing or doing wrong?

Hard to say at this point.  The 4103 is for use on a F.I., auto trans vehicle so
we will assume your BWM has an auto trans.  ( If it does not, then DO NOT install
this remote start system on your car.   There are other units available designed
to be safe with a manual transmission. )

Here is wiring info.  Verify all wires with a DMM prior to connection.

H1/1 LIGHT GREEN/ BLACK FACTORY ALARM DISARM
H1/2 GREEN / WHITE FACTORY REARM
H1/3 YELLOW (+) IGNITION OUT (TO ALARM)
H1/4 WHITE/ BLUE (-) ACTIVATION INPUT
H1/5 ORANGE (-) GROUND WHEN LOCKED
H1/6 BROWN (-) HORN OUTPUT   
H1/7 RED / WHITE (-) TRUNK RELEASE OUTPUT
H1/8 BLACK GROUND                 Chassis Ground
H1/9 WHITE (+/-) LIGHT FLASH             gry/purple, gry/yel    @ light switch 
     Set 4103 to (+) and use diodes or relay to isolate wires. 
     Here is a diagram from Bulldog Security :

H2/1 BLACK/ WHITE (-) NEUTRAL SAFETY SWITCH INPUT      to Chassis Ground
H2/2 VIOLET/WHITE TACHOMETER INPUT WIRE          black (AC)    @ diagnostic conn.
H2/3 BROWN (+) BRAKE SWITCH SHUTDOWN WIRE              blue/red (+)  brake pedal switch
H2/4 GRAY (-) HOOD PINSWITCH SHUTDOWN WIRE    Hood Pin
H2/5 BLUE/WHITE (-) 200mA 2ND STATUS/REAR DEFOG       N.U.

1 PINK (+) (30 AMP) OUTPUT TO IGNITION CIRCUIT        Green @ Steering Column
2 PURPLE (+) (30 AMP) OUTPUT TO STARTER CIRCUIT            BLACK / YELLOW @ Steering Column
3 ORANGE (+) (30 AMP) OUTPUT TO ACCESSORY CIRCUIT     Purple @ Steering Column
4 RED (+) (30A) HIGH CURRENT 12 INPUT           Red @ Steering Column
5 PINK/WHITE (+) PROGRAM OUTFOR ACC2 OR IGN2               N.U.
6 RED (+) (30A) HIGH CURRENT 12V INPUT         Red @ Steering Column

Neutral Safety Switch must be plugged in and set to ON.
Program 4103 to Tach Mode and perform Tach Learn process.
Use the built in diagnostics to determine fault :
led flashes shutdown mode
   1     System timed out
   2     Over-rev shutdown
   3     Low or no RPM, Low battery (for voltage & virtual tach modes)
   4     Transmitter Shutdown (or optional push button)
   5     (-) hood shutdown
   6     (+) brake shutdown
   7     Neutral safety

The Neutral Safety wire, BLACK/ White, must be connected and show chassis ground to allow a remote start. 

Times 2 with Joe on the Hood Pin.  Very important safety feature.

it works perfect!!! i just need to finish the install with the brake wire and the hood pin. there is a factory hood switch so i might try to utilitize that to make it easier. the hood raises up opposite that of normal cars. most cars hoods go this way... (< = front of car) <\. mines goes this way </ and then is pushed towards the winshield to latch after it has been layed down. the whole fact that you have to push it towards the windshield makes the hood pin that came with the remote start difficult to install. therefore i will use the switch factory installed for the light or whatever it was. (there are 2 switches on the hood, one of them was for the light. neither of them work anyways). thank you for straightening this whole thing out. it's taken me a LONG time to figure it out. saved me $200 for install. all i ended up spending was about $50 for everything.

ok i looked into it a little more. when i dissconnect the tach wire from the remote start the problem goes away. when you test the tach wire with a dmm the voltage goes down when switched to dc as you press the gas. when switched to ac the voltage goes up. im thinking this has something to do with it. if i understand right, most cars the voltage will go up on dc when you press the gas. what do i need to fix this? do i have to hook up the wire in a different area? im not sure what's between the sensor and the tach. wiring diagrams say there's nothing.

(https://www.wedophones.com/Manuals/BMW/1989%20BMW%20525i%20-%20535i%20Electrical%20Troubleshooting%20Manual.pdf) scroll down to instrument cluster and move forward a couple pages til you find the tach.

might try finding a different wire or something.

also i haven't yet installed the brake wire into the remote start yet. do you think that could be the problem. then again it shoudln't be messing with the tach like that.

I believe the 4103 has a jumper setting for Tach threshold.  Try switching the jumper to ON and re-learning the Tach signal.

Not sure if this is the latest manual, but  it might help with the jumpers & programming.  ( Avital is a DEI brand like Viper )

i got everything to work. i used the "start by voltage" feature instead of the tach. it work perfect in that setting. doesn't over crank and it starts everytime. not for the little things.

thank you everyone. you've all been a big help!

im trying to get the parking lights to come on when you lock and unlock the doors as well as remote start the car. i hooked up a relay to at least one of the lights but it wont even click. as much as .07 volts dc run through the parking lights wire from the remote start. do i have the wrong relay? it says 60A on the relay but i thought it was a 30A. is it just there is not enough voltage to trigger it?

also i would like to install an anti-grind relay but im not sure how to do that. the other day i turned the key too far after remote starting it from habbit when i didn't have the remote start.

im sorry but your post is confusing me. im pretty sure i have the lights figured out so that's not my issue anymore. and as far as the tach goes i set it to voltage instead of tachometer so i don't have to hook up that wire to my tach. that problem was also solved.

as far as the anti-grind, it will only grind if i accidentally turn the key too far after remote starting. that's what i want to prevent. it's too much of a habbit to turn they key all the way when i get into the car wheather it's running or not.

i think i get it now. what kind of relay do i need though? and a diode between 85 and 86?

Standard automotive Bosch style 30/40 Amp SPDT relay, with 5 wire harness.  Diode is a standard blocking diode. 1N4004 ( or 1N4007 ) will do nicely.

Here is one way to wire the relay :
Relay Pin 85 to 4103 (-) 200mA Status Output
Relay Pin 86 to BMW Ignition wire ( or 4103 Heavy Pink wire, it goes to the same place )
Relay Pin 87A to BMW cut Starter wire - Ignition Switch side
Relay Pin 30 to BMW cut Starter wire - vehicle side
Relay Pin 30 also gets the 4103 thick Violet Starter wire connected.
Relay Pin 87 not used - insulate

Oops, sorry Howard, I missed your anti-grind diagram.    ( That'll teach me to text, drive and eat a corned beef sandwich at the same time while navigating a round-about..)

when i try to program the 4103 to lock and unlock with ignition it wont work. i turned the key on then off. held down the program button until the light flashed once (menu 1) then pressed the button twice (feature 2 - ignition locking) held the button down and kept it down. the light flashed 2 times (indicating feature 2 is selected) then pressed the unlock button on the remote (switch feature options) but when i pressed the unlock button the light doesn't flash anymore and never indicated that option 2 has been selected (option 2 being ignition locks ON). i released the button and tried the ignition to lock the doors (even when the doors were closed) and nothing happened turned the ignition off and nothing happened. i even tried programing the unlock feature but again the light just stopped doing anything after i pressed unlock on the remote. if i pushed lock it would go back to default (which is OFF for both features) what is going on?
