97 Mercedes C280, Viper 560xv

Sorry to bother you guys again but would the following works ?

I understand that this car has a split park light system that gray/white(+)and gray(+)at headlight switch.

Wtih double relay to isolate the two wires mentioned above:                                                                                              #1 relay

86->(-) from Alrm(H1/2)

87->(+)signal either gray/white or gray

85&30->+12v fused

#2 realy is the same as above with #2 86 goes to alarm(H1/2) and 87 goes to either gary/white or gary

Does this look fine?

I am trying to understand a bit of relay system and to be safe. Thanks again once more.

bobk, thaks a lot for your advise. I have decided to take one relay with two 6amp diodes.

I do really appreciated for your help, and thank you again!!

Hi, earlier I have I asked about positive light flash connection to my car and I have tried two diodes with one relay but it does not work, so I have decided to use TWO relays connected to my car(C280-1997) with viper 560xv.

I understand that my car has two split positive wires, (+)Gray and Gray/White(+) and I have tested them to be correct. The question is Which Diagram is correct as outline below ???

                                                          DIAGRAM-1

                             87->+Signal from Light flash  87->+Signal from Light flash

86->to Alarm+                              85->Ground   85-> Ground

                            30->+12V                                   30->+12V

                                                 DIAGRAM-2

                            87->+Signal from Light flash  87->+12v

86->to Alarm+                              85->Ground  85->Ground

                             30->+12V                                   30->+Signal from light flash

#86 pin from two relays are connected together go to H1/2(White wire

Any help will be greatly appreciated, thank you.

Hi gus, I have been trying to connect  one of 4 wires from remote harness to the  2nd acc at the ignition. The 2nd acc is positive and the orange wire from the remote harness is Negative so I need to put a relay but I do not know if the relay wiring between the 2nd acc wire and the orange wire.

#86 from remote start wire(Orange)-Negative

#87 from 2nd acc ignition wire(Pink/Green)

#85&30 to +12V

I am not sure if this connection is right or not.

The 4-pin remote wires is the one that connected to XCRS 500M

The car is C280(W202), 1997.

Thank you in advace for your any help.
