installing immobiliser to e36 ( under construction)

[patrick S]

so you want to install immobiliser like this one?
if you know how to solder wires then i think you will qualify


step first
open up fuse box, you will want to make thieves life as hard as possible.
you need torx screwdriver. unscrew two front screws, be careful, apply pressure, do not break torx pattern on heads.also open drivers side under dash to get acess to wires and screws that hold fuse box in place. unscrew these 4 screws to get fuse box loose

now you can get acess to fuse box rear screws. unscrew them carefully. open the box



now its time to locate circuits that you will immobilise
for example green/purple wire coming from fuel pump fuse (17)is ideal. measure voltage on wire( test light or tester one lead grounded):
ign off- no voltage
ign on- no voltage
crank and run- +12
when car running, cut the wire- if engine stops( after couple seconds), you have found right one.
you can connect it temporarily together to locate another circuit
after that connect it to immo as on its wiring diagram

second circuit can be ignition for ecu
it is green wire going from connection point to engine harness connector outside fuse box
it has power when ignition is on
if you cut it engine will stall immediately, remember that there are couple wires in that connector cut the right one, if you miss, connect back and be more careful next time

now connect it to immo wiring ( connect now fuel pump wire too)
remember power comes from ignition lock and goes to engine harness:
twin wires for immobilising, third ignition sense for immo


power up immo:
red pernament power
brown ground

solder all wires



cut sharp edges

isolate all connections



locate drivers side door switch wire near drivers side speaker
brown/gray/yellow

never connect immo circuits on steering column. it is too easy to reconnect


install led and antenna into center console. antenna can be located anywhere where you want, it does not work through metal
