the locks are controlled by a data bus cable. the only way to interface is with a bypass that hooks to the purple wire og the obd2 port. Such as a 456G made by directed. also you'll need a 555l if your going to install a remote start. i don't have a diagram but most the colors are the same and have been for many years. except parking lights the newere cars have switched to negative usually a gry/blk wire.

Its not that bad. The door locks you dont need a module for. It is a sngle wire (-) system. (-) to unlcok and (-) thru a 465 ohm resistor to lock. Use a relay like so:

Pin 85 to the (-) lock out put from alarm

Pin 86 to constant 12v+ fused

Pin 30 to the ORANGE / black at fuse box (Lock/unlock wire)

Pin 87a to (-) unlock output from alarm

Pin 87 to ground

If you aren't installing a starter then you dont have to worry about the passlock so it should be a piece of cake.
