97 Mercedes C280, Viper 560xv

Well, i am confused with the relay diagram in the door lock on the left in the car security................I see the relay diagarms in there.

So, All I have to do is to take the both lock(-) and unlock(-) wires from the car connected to the viper brain without relays or 451M, I just want to make sure that I will not short anyting.

Thanks for your advise, guys

Hi guys, I am trying to install viper 560XV in my mercedes C280(W202), 1997 and I have been checking whether or not to connect all four doors to the brain or not.

I have found one such connection in the bulldog site and the diagram showing

all connecting with diodes with each connection, is this right ? my door pin switch is negatives and when each door opens, the dome lights up.

I am not professional and I need exact diagram, please help.

Thank you so much for your help!!

Thanks for the diagram showing colours of wires for the door pins, what I am not sure about is how to connect these wires to the brain(primary harness(H1).                 

The input wire of the brain is GREEN for the minus door trigger, How do I connect this wire to the wires from the door trigger wires from the car ? no diodes or should I put one for each wire coming from the pin switch to this green wire?

Should i solder each diode to each wire of the door pin before connecting to the green wire?

I do appreciate for your great help, thanks

nuugen, thanks for your direction.

I just absolutely make sure what I am doing right or not, so the diagram for connecting each diode looks like this ?

Again, appreciated so much for your help

Hi guys, I am installing the viper 560xv in my Mercedes C280(W202),1997 and I got stuck with the selection of wether to switch from negative to positive for the wire that goes to H 1/2 in the main harness of 12 pins(Viper brain).

I have no idea if the parking light circuit that draws 10 amps or more, if more then I should switch to negative. I have recently changed the head light unit from halogen light unit to xenon head lamp unit that requires more than 10amps fuse so I changed the fuse from original 7.5 amps to 15 amps.

Does changing the fuses from 7.5amps to 15 amps affect this light circuit that draws more than 10 amps? if so, I should chnage the internal jumper to (-) light flash ?

I am confused, any help will be greatly appreciated.

Thanks guys, it sounds like safe to use the relay. what type of relay diagram should I use ? I checked the "Light flash" on the left under car security and found couple of wiring diagram.

Should i use this BASIC LIGHT FLASH, that is 87&85=fused 12v+ and 86 to (-)alarm light flash output, 30=positive parking lamp wire(at the light switch)  Or TWO WIRE LIGHT FLASH DIAGRAM??

My head lamp wire shows positive(+), checked with DMM

As for the headlamp(HID), I just changed from halogen to exnon(Bosch oem) head lamp unit(not just the bulb, complete assembly) and no relay. so far it is working

Thank you again for your professional advise
