Hello. I have a 320i european with no alarm. I am going to fit the original horn and 2 sensors, shock and internal microwave (both not original, both with 3 wires - ground, +12 and negative trigger). There are no problems with siren, the connection is simple (+12 from fuse 67, ground, siren wire and stdwa from GM V).
My questions
1. Can I use stdwa as ground for those sensors instead of body ground (do not want them to be active permanently, but only when alarm is armed)? (the original UIS sensor has a ground wire but the tilt sensor has not).
2. where shall I connect the trigger wire from each sensor? to GM V in places of original sensors? then which one? (there are 3 pins - 5 Park Angle/Tilt Sensor, In (B28-4),,,, 19 Signal, Interior Protection II (A123) (Convertible Only),,,, 24 Signal, Interior Protection Unit I (A121))? or split them to one input, or split them to hood switch? Will the GM V recognize these sensors?
Thanks in advance!
