I have successfully installed a remote start and Remote Keyless Entry system on a 2003 Dodge Ram 1500. I am wanting to add another relay to auto unlock doors when automatic transmission is placed in Park position. Can anyone tell me the correct wire and polarity to tap into for my relay circuit? It would need to be wired in such a way that it would generate a single pulse, so the relay would not always be activated...any ideas?

Thanks!

What diagram did you use for the 2003 Dodge? Is it the same as the 2002? Does this truck have a anti-theft system?

what you can try

12v brake trigger to 85

86 to park wire behind cluster invert to neg.

30 single pulse generator output

87 to neg of alm unlock to door locks

this circuit is active when brake and park wire is used. good luck

you will also need to trigger the single pulse with the brake wire and park wire also
