viper 160xv lights in a dodge intrepid

its a neg 110 ohm risistor wire. you need to take the white park lite output put a 110ohm resistor in line and connect to the - yelow wire at the headlight switch.

best buy does not usually hook up the ststaus, valet switch or horn. its all extra like trunk and dome sup.

tell your installer to hook up the parking lights. its not really an option. as kartuneman mentioned its used for confirmation.

if you want to fix the lights yourself, do it like so with a relay

85 - ground

the 160xvl has the anti-grind feature in which you need to cut the starter wire. IMO the valet switch should not be considerd an 'option' since a customer may need to use it. its next to no extra work to make it accessible. it will only save you time in the future if a customer wants you to change common features like parking light flash/constant, run-time etc. the LED doesnt have to be mounted as its not THAT important, although if its not mounted or the horn is not connected, it can be hard to program features in the future. i usually wire-tie it under the dash and put a piece of tape over it so the customer doesnt see it glow. if i ever need it, its accesible. as for horn and parking lights, i guess its debateable as some shops charge extra for them. i always hook them up for no extra charge.
