ok, I am adding power door locks to my 85 FB (and connecting them to the keyless entry alarm system) and need some help interpreting the wiring diagram / instruction that came with the previously installed alarm.

According to the alarm diagram (see pics 1 and 2) there are six wires to be connected to the door lock system and I can't make heads or tails of the wording (see below). The 3rd picture is of the power door lock system in the car.

Can someone pease help me figure out where I need to attach the 6 wires from the alarm??

greatly appreciated.

 

pic #2 from the alarm package corresponding to the 6 wires identified in the above pic:

 

pic #3 from the car wiring diagrams.

The thing I am trying to figure out is where to hook the 6 wires from the alarm to?

Can you guys help me out???

thanks

 

Can any electrical wizzes hepl me out here? For example, in pic #1 it says connect the "brown/blue" wire to the switch side of the factory door lock motors. I am confused though (switch side???) because if you look at pic #3 the switches go to the relay not the motor.

Can anyone help me out, please???

thanks.

 

im not sure ill be much help, but from the lack of posts, any is better than nothing

u will only need to use 3 of the 6 wires in that diagram, the common connection, and the normally open unlock and normally open lock


most lock/unlock switches have 3 wires +12,lock,unlock
all that is done is that when u press unlock it applies +12 to the unlock wire, same goes for lock.

all u would need to do is connect the common wire from your alarm to the orange wire in the 3 wires. then connect the normally open unlock to the black wire, then the normally open lock to the light blue wire and that should be it

hope this helps

 

thanks for the reply johnsen. THe only thing though is that in looking at the diagram the "normally open" wires are connected together. THis would mean that they would not work independently for lock and unlock functions, right???? I think?.?

 

in that case, i think the alarm completely bypasses the door lock/unlock relays, all one would have to do then is locate the wires coming off the relays that connect to the door lock actuators, and attach ur normally open wires to it, try to see if it works, and it the lock button on ur transmitter unlocks it, and the unlock locks them, then the wires would be reversed, could be wrong,sure would be nice if others could help with this one

 

ok, thanks. I'll check that out.

 

okay, i can understand now, notice how to wires on ur alarm diagram have numbers next to them, like the common have 30
and normally open ones have 87

well how it works is that ur alarm has built in relays which switch on and off with your keychain transmitter or device,

one question on the alarm box, the wires that come off it, those normally open wires are they connected together or seperate?

 

yeah, I think you hit the jackpot, I went on the manufacturers website to try and find out more info and those 6 wires are for built in relays. However, I also noticed they use the same diagram for two different models. Mine just happens to be the lower model where those relays are optional! So I'll have to run down and check the alarm in the car but I am pretty certain that I won't have 6 wires, probably only 2. The info for the lower model says only a 0.3A output for doorlocks (not enough to power the motors) so it must just have trigger wires for the relays (notice that diagram said 20A).

Now we are getting somewhere! Thanks man

 

that would be weird that only 2 wires would be there, all 6 six should be there to accomdate different power lock schematics


but see if your alarm has the normally open wires connected together then we can go from there

 

ok, finally back to the door locks! Sorry for the delay, the mechanical work (clutch etc) had to get done.

I have the door locks installed. Tested the motors first...check. tested the factory relay....check. Looked at the alarm and there IS only two wires.....the two door lock common wires. As mentioned earlier the info says 0.3A output for this model (20A is for the next model up). Do you think 0.3A is enough to activate the coil side of the relay to pull the bigger contacts closed so that the power accesory circuit puts curent to the motors????

 

0.30amps should be plenty to trigger the door lock relays,

 

CRAP! they don't work When arming or disarming the alarm it does not activate them. Wiring checks out and ground on the relay.

THen I checked the leads from the alarm with my volt meter just to confirm that there is a signal. THere is but only 0.631 V. I then switched a dip switch in the alarm (after reading the book) to set the pulse to 3 seconds thinking that the digital meter may not be seeing the one second pulse.......no go, now there is a 0.631 V signal for 3 seconds. AHHHHHHHHHHHH! ANy ideas as to what is going on?? I assume that this is way low of a voltage to send current to operate the relay, right? It should be 12 volts right??

HELP!

 

correct, it should be 12v, i would think that there might be something wrong with ur alarm brain, and does your remote have the lock/unlock buttons? or just locks when u arm?

 

just locks when you arm. THe trigger wires send a signal. THere is a signal, just not the right voltage. THere are a bunch of little dip switches inside the alarm but is does not discuss them in the users manual.

 

I wonder if the issue is with these dip switches??? Any ideas as to how I could find out what they do beside screwing around and risk messing up the alarm??

Also, is there any way to boost the signal from those trigger wires from the 0.631 V to 12 V????

 

Anyone? any ideas?
