DIY: E46 Shock Sensor Install

loki · 06-30-2002, 01:06 AM

Thanks to Dave (Osbee on the board) with his post about adding the sensor... I got inspired, purchased a similar product to the Audiovox sensor he used, and installed it this afternoon.

DIY: E46 Shock Sensor Install

This is a great, easy, and affordable addition to the OEM alarm and adds the level of security you'd expect but never got with the factory hardware.

happy modding!

I assume that's what this is right?

loki · 06-30-2002, 11:21 AM

think "Hit and Run", and you'll get the idea of why this is worthwhile.

StreetTrixE4six · 06-30-2002, 11:29 AM

Did you have to run the power all the way to the battery or was there a wire you spliced into?

jun · 06-30-2002, 01:32 PM

Loki,

Where did you get the sensor?

Dev · 06-30-2002, 11:11 PM

Ummm...someone go do a Hit and Run test on Loki's car to see if the thing works.

J/K

From the pictures, doesn't seem too difficult. Now where can we get a hold of this sensor? Radio Shack?

mickey513 · 07-01-2002, 02:10 PM

Any audio/alarm shop. It should cost around $20, more or less depending on where you. I recommend you go with the DEI shock sensor instead of the audiovox one. The audiovox is made by radio shack

vinnymac · 07-01-2002, 02:21 PM

Damn, now I have to spend more money and add another mod to my car. where and how much?

vinnymac · 07-01-2002, 02:23 PM

someone explain to me how this interfaces with the OEM alarm...what is triggered when the car is bumped? I'm confused here...

JACOB NJ · 07-01-2002, 02:28 PM

the shock sensor gets power from the cars electrical system.. then triggers the hood pin switch when the car is bumper or tampered with .. so the alarm is in turn set of by the hood pin switch.... loki write up is great.. not sure if he used the diodes on the install ..but the paperwork for the 504 from what i remember suggest diode use so the shock sensor does not back feed from the pin switch the the sensor but vise versa.. but i dont think its necessary but dfiently a plus.. i also had all power and wires inside the car.. nothing was seen under the hood but all was hidden behind the glove box.. loki defiantly has the easier install there but i guess my mentality of clean and simple is just because of the work i do.. and how i do this daily.. i try to keep to out of sight out of mind

either way will work fine

anytime

if you ever need electrical guidance just holla

ptsao · 07-01-2002, 02:42 PM

thanks,

Just a thought.

my previous shock sensor is mounted on a clip like sheet metal so is not rigid against the body of the car.

I wonder if that will just make it more sensetive, or the new shock sensor is better.

I'm going to get his done this week.

jestr · 07-01-2002, 03:47 PM

Nice write-up Loki

I'll have to do that soon too... BTW did you choose the more sensitive setting or the less sensitive setting and how sensitive is it?

JetBlackE46 · 07-01-2002, 05:14 PM

i have a 2000 323ci and i don't have that hood pin switch. did it come with the factory alarm?

Comes with the factory alarm.

loki · 07-03-2002, 02:21 PM

I choose the green (more sensitive) wire. With the stock sensitivity setting it seems fine. Will go off with sudden impacts (like a kick to any tire) but not general rocking.

If you desire it even more sensitive, you can adjust by a screw on the DEI sensor or mount it to a part more susceptible to shock.

BTW, the hood pin switch should aleady be there, the factory alarm kit only includes the horn, motion sensor and tilt sensor.

good luck!

JetBlackE46 · 07-03-2002, 08:28 PM

how can you hook up the dual stage shock sensor?

i want it to chirp on light shocks and trigger the alarm on a hard shock...anyone know?

also, is the purple wire a positive or negative trigger?

sycE46 · 07-03-2002, 11:48 PM

anyone know how long the alarm goes off before it turns off?
