hi here is a link for the info you requested the locks need a data bus module or you have to do reverse polarity at each door lock motor the module works better and is safer.

the only things needed are the pink, white = ignition
orange =acc yellow= starter and red= constant
you only have to use the braown 2nd acc wire when cutomer has an aftermarket radio he wants turned on by remote start.

also passlock wires are yellow 22 guage wire and black 22 guage wire.

white= brake
grey black negative parking light wire at switch cant use flashing parking lights on this wire cause the headlights will flash as well so you have to set the p lights to constant.
