Installed a viper 4204v remote start and keyless unit. The door lock outputs are (-). I located the light blue and the white wire in the kick panel for the door locks.Question is, do I need a relay? Is there an option to make the (-) outputs become (+) outputs on the viper units? I have searched the forums all night and could not find anything directly related to my vehicle. Any help would really be appreciated. Hoping to not need a relay.

On most remote start units there is only a negative lock outputs so you will need to wire a relay or use a 451m or door lock relay module

You will need 2 relays or a dei 451m to change the polarity to positive.
