Hi guys im not actually breaking into the wiring all im using the alarm for is to power door locks, it will have a power and an earth only, ive fitted a factory boot lock with solenoid attached and a drivers door lock with solenoid attached,when button pressed on fob it will power drivers door solenoid instead of key and all locks will go down, boot is on a boot release switch on dash, im trying to find out why there is 3 wires on boot solenoid, im presuming there is a power and an earth and one extra for feed from a release button , the can bus system is not wired into cdl so fiat dealers tell me, but im not breaking into system anyway so that wont matter, justb looking for wiring diagram
