Default 520t backup battery wiring finding ( - ) instant trigger input

The blue wire coming out of the 520t wants to connect to a ( - ) instant trigger input where is this?... do i tap into the H1/7 (blue multiplex input) on the clifford matrix 50.5x?


and then i have a AU94tm motion sensor, "*In the case of a backup battery, connect between the backup battery and the car, not between the backup battery and the alarm."

from this graph it looks like i connect the motion sensor to the alarms blue (-) multiplex input H1/ 7 wire thats already connected to the ( - ) trunk trigger input ?

Motion Sensor Alarm
Red Red (constant 12v)*
Black Orange (ground when armed)
Green Green (negative door trigger input)
Blue Blue (trunk trigger input) or Light Gray (hood pin input)


and i also have a hood pin already mounted if that makes any difference.

i stole these pictures from my other thread just to get a visual for those who dont know what im talking about... i guess my DEI shock sensor harness have the wrong colors?


okay i have some pictures, the above pic showing the DEI 50.5 alarm brain connected to the DEI shock sensor.... and the crime guard AU94T motion sensor plugged into the harness.


DEI shock sensor shown above, wire colors in accordance from L to R: pin1- orange and a (blue loop that goes into pin 2). pin2- blue then pin3- black and pin4-red.



shown above is the au94t with wires in accordance from L to R: pin1- green, pin2- blue, pin3- black, pin4 red.

Yes, that's one of the best places to connect it, but you'll need to diode isolate each of the triggers. Otherwise weird things will happen, ie the cluster light indicating the trunk is open will light when the hood is open.

You could also tie it in with the shock sensor's instant trigger, but again, it's recommended to diode isolate it.

The statement that you quoted is referring to the red constant wire. But if you connect the sensor's black ground to your alarm's ground-when-armed, then it's not necessary.

what is wrong with the 50.5x shock sencer that you want to add anothor? And the wire code on it is not the wrong color. Its like this for a reason. Clifford is dei highest line of alarms. Its shock sencer is the only one out the whole line this is not plug and play with other dei alarms. Notice all of dei shock sencer are clear and use a red-black-green-blue wire harness. Except on the clifford line. I notice its a lil better then the clear unit. But I have not has any problems with the clear units either. The problem I see is that your going to use the dei sencer with the au. Now the problem you are going to have is trying to match the two toghter. I don't see how your going to match both soft and hard impact from the dei unit with the au unit. The au unit both the light impact and high impact are adjusted independently of each other. The dei unit is overall.

The back up battery neg trigger output should be tag to the trunk input. Reason I do this is because no theif break into the car from the trunk. And second if the hood is tampered with to many times without it being reset the alarm will bypass it. So if the battery is disconnected and bb is tagged to the hood pin the alarm will not trigger because that zone is bypassed.

The reason the dei shock sencer wire is looped is because dei makes the units multiplex now. anything under .8 sec will be a warn away. anything over .8 will go to full trigger. The shock sencer will report on zone 1. The extra blue wire will report on zone 2.

The way you have the motion sencer written up you not going to know whats going on. Its reporting on everything. lol.

I see that you sell this alarm. You should have all this info. How do you help your customers?

okay so run the brains blue H1/7 (-) multiplex input to the (-) instant trigger input in the oem wiring harness (but how do i locate this wire?) .... and then tap into the brains blue wire with the blue wire coming off my motion sensor along with a blue wire coming off my DEI shock sensor... can you confirm what i said please?

when i tap the two blue wires off my AU94tm and DEI shock sensor into my clifford brain, would you reccomend using diodes sending the electricity towards the brain?

are you talking about the au94tm sensor?... so connect the black au94tm sensor to the orange (ground when armed wire?)

ahh its all making sense now, its weird even the manual had the wire colors switched around.

its an au94tm motion or proximity sensor, i think you have them switched up?

so does the backup battery activate when a zone is triggered?.. and the trunk is the least likely to get memorized by the alarm and bypassed?

i thought the motion sensor would work in conjunction? and i dont help any customers yet because i am such a noob... a can just get a good deal on them through a buddy.

oppes, Your right. I did get them mixed up. sorry about that. My misstake. The back up battery will kick out a neg trigger only when it sees a voltage drop. Thats what triggers the alarm. Even if you diode them the alarm will still bypass the hood pin input if its violate 3 times in a hour. Thats why I put it on the trunk. The trunk can be bypassed too. But its unlikely because a theif is not going for the trunk. Because rule number one for a theif is to get to the hood or engine carpartment first. No matter what. Not the trunk. They have to get to the siren and the car battery first so they can try and kill the alarm power. Then they get into the car to do there dirty work. Thats how it goes no if and or butts. But with a back up battery the theif can't do squat unless the siren is in the engine bay and he clips the wire to it. Thats when is over for your car. unless the alarm is stealth with gps tracking or has some extra sirens

yeah my siren is in my fender and i ran the red and black wires through a factory grommet under the dash that are going to be fed through the rear of the vechile to the alarm brain and BB that are located in the drivers side rear 1/4 panel under the plastic...

so on the DEI shock sensor should i use the precut blue wire (on the alarm side of the harness) to attatch to the (-) input wire of the trunk trigger?

Man I just got back from Salt Lake. I could have helped you out. I'm trying to get a job at BB out there so I can move. There's a lot of ricers out there! I probably wont be doing many stealth installs though. Somehow I don't think car theft is a big problem in Utah.
