Printer Friendly Forum Posts - 87 300E, Clifford Matrix RS 3.5

I just bought the Clifford Matrix RS 3.5 to install in my 87 300E. Has anyone installed an alarm in an 86-89 300E Benz? I am definitely a Newbie to alarm installation, so I need some help. I have located most wires but have no Idea how to hook up this 451m relay that came with it and there is nothing in manual about it. There is a 3 prong plug with GREEN/ RED / blue to plug into alarm. And there's a purp/bk and a purp that splice together and into a fuse. A GREEN/ bk, wht/bk, BROWN / bk, and a blue/bk. And the manual says use type-e config for 85 and newer mercedes and to modify door lock harness (H2) , but there is no info in manual about it.

Also, on the relay satelite there is a 4 prong connector next to the ribbon cable that has no instruction about it. It says, Blue(-)status output, orange(-)200ma 2nd acc output,purp - 200ma starter out, pink - 200ma 3rd ignition out.

And the H1/3 WHITE/ Blue remote start - activation input, what do I do with this?

And they gave me a Clifford single zone prox sensor with a bk rd and orange wire. Do I hook the orange wire to H1/6 multiplex input,zone 4? Or what?

here is what i have for the door locks:

the satelite relay pack is for adding extra ign./starter wires in case you need them

Is there someone who can check the matrix 3.5 manual online and help me out?

Any idea what the H1/3 remote start (-) activation input is for?(page18)

And what about the H3/5 Bk/Wt neutral safety switch input. Any idea where this wire hooks into my car? (page 26)

I have located most wires but have no Idea how to hook up this 451m relay that came with it and there is nothing in manual about it. There is a 3 prong plug with GREEN/ RED / blue to plug into matrix 3.5 alarm. And there's a purp/bk and a purp that splice together and into a fuse. A GREEN/ bk, wht/bk, BROWN / bk, and a blue/bk. And the manual says use type-e config for 85 and newer mercedes and to modify door lock harness (H2) , but there is no info in manual about it. I have looked at vac lock relay wiring diagram but it doesn't help because I have the 451M relay pack that is pre-wired and not the reg relays.

Thanks again

h1/3 WHITE/ blue - nothing, leave it out.

h3/5 blk/white- ground it, assuming its auto tranny.

maybe david will help you w/ the 451m, cause i dont use these part, i use the regular bosch types which require 2 relay setup or lock and unlock.

"The two most common elements in the universe are H+ and stupidity" (Ellison).

The back of the 451M relay says: 3pin plug- green (-) lock input, red (+)pos input for coils, blue (-) unlock input. I know where this plug goes.

The 5 wire harness is labeled:

purp/bk lock/unlock normally open #87

grn/bk lock output#30

wht/bk lock normally closed #87a

blue/bk unlock output #30

BROWN / bk unlock normally closed #87a

Here is what someone else told me but don't understand what to do with the last 4 parts. Mine has a purp/bk wire that splices together with the purp wire, then connects to inline fuse. :

GREEN/ black and BROWN / black are tied together(lock relay 30, unlock relay 87a)

WHITE/ black goes to the switch side(lock relay 87a)

blue/black goes to the motor side(unlock relay 30)

purple goes to 12v(unlock relay 87)

PURPLE / black goes to ground(lock relay 87)

ground to 86

12v to 85

BROWN / bk unlock normally closed #87a

PURPLE / blk-ground
GREEN/ blk-tie w/ brwn/blk
WHITE/ blk-driver's drlock wire(meaning cut the wire)
blue/blk-vacuum side wire
BROWN / blk-tie w/ GREEN/ blk

if youre to take a bit of time to study the relay diagram on this site, it shows that the vacuum is active w/ two diff output polarity(+ and -) to create lock and unlock.

Tran - So the purp/black goes to ground? Why does it have a fuse? And where does the relay get 12v from because I thought that the purp/bk was for 12v?

-------------
BOOM, BOOM, BOOM BOOM....

i think because the red wire(3wires harness) is 12volt (+) already, the only thing thats left is ground and ground is missing from the whole diagram. thats PURPLE / blk #87.

to test it, dont plug the 451m to the vacuum yet. w/ a dmm, test the wire that goes to the side of the vacuum wire to see if youre gettin both neg and pos. if youre, then youre set to go.

Why do you think the PURPLE / bk has an inline fuse?

"The back of the 451M relay says: 3pin plug- green (-) lock input, red (+)pos input for coils, blue (-) unlock input. I know where this plug goes."

you stated that the red wire is (+), so then i assume that the other 87 pole is ground since the 451 has not receive ground yet. remember that the 451m is consist of 2 relays and i referred it to the diagram on this site.

i think someone here master this unit already, cause i dont.
my bad....

I am almost done installing the 3.5 matrix in my 87 300E but I need help with 3 more things.

1) How do I hook up the 2 wires(L&R) for my park lights to the 1 light flash input? 1amp diodes?

2) I want to hook up this single zone clifford proximety sensor to my matrix 3.5. It has a red,bk,and orange wire. Can I connect it to the blue wire that is not used on the factory shock sensor plug at alarm? Or how can I connect this prox sensor?

3) Last, do I hook my trunk pin trigger to the blue multiplex input H1/6 ? The instructions don't say anything about connecting the trunk pin trigger to alarm, but the quick reference labels the multiplex input as trunk trigger input.

I'm almost finished and really appreciate all the help and advice. I'm soaking it all in

1)two 1amp diodes, band facing the parkin light wire(s).
2)the impact sensor has a dual stage. you can plug to either wire w/ a diode band facing the prox sensor, depending what you want, a warning stage or a full stage.
3)thats the one!!!!

Can I hook the proximety sensor up for warning and full stage?

Also, do I need to hook the factory disarm wire up to my 87 300E? The manual says to use relay. Do auto parts stores carry the correct relays? What kind of relay/s should I get? I will need a relay to hook anything extra to outputs too, right?

Thanks again. I am a beginner to alarms and am soaking all this in.

BOOM, BOOM, BOOM BOOM....

since your proximity is a single zone or stage, you can only pick one.

if you need to use a relay to what the specs expressed, then do so. you can get them at radio shack for ~3-5 bucks each.

you know where the diode goes, so i wont explain how to w/ the relay....
85-(-) trigger from single stage
86-(+) fused
30-ground
87-to the impact sensor line.

1) Use 6amp diodes bands towards the light switch, 1 amp will make nice flames and smoke.

2) single zone prox sensor cannot give you dual zone.
red to 12V, black to Orange ground when armed and the orange on the clifford to the blue multiplex wire.

The plug that exits the alarm module has a blue wire that is not connected to the impact sensor. Is that a multiplex wire that I can use too? Because if I hook the prox sensor to the blue multiplex wire H1/6(trunk input) won't the alarm confuse the 2 zones? Or does that not matter/apply?

it doesnt matter. i think it owuld be a good idea and quicker install. show when it goes off and the trunk icon appears, then youll know that its your proxi

I will attatch it to the trunk input then so I can see the trunk symbol as you stated.

For the relay that will disarm the factory security system, how many amps should it be? And is it even necessary to do this since my factory security system gets disarmed when the doors unlock?

Thanks again for all of your help. It's definitely not going in one ear and out the other posted_image

I will post tonite with the results of my install.

BOOM, BOOM, BOOM BOOM....

INSTALLATION WAS A SUCCESS!!!!

I am very satisfied with the results and the system overall. Remote starting makes me feel like Michael from Knight Ryder posted_image

Thanks again for all the help!!!!!!!!!!!!!!
