I'm installing a Prestige APS57z with an ADS-ALCA bypass on a 2015 Ford Fiesta. It appears from the ALCA installation guide that it doesn't interface with the door locks on this vehicle which is a shame. So I have to hard wire which I've never had to do before. I have attached the ALCA guide and the door lock wiring diagram I found. I just need someone to double check that this is correct. Also, will IN4004 diodes work for this?

yes the in4004 diodes will work fine, they are 1 amp diodes. Just make sure you have the stripe side (cathode) pointing the right way as shown in the diagram.

yellow/gray (key lock); blue/brown (detection)
violet/brown (key unlock); blue/brown (detection)

all wires should be in the drivers door boot

Thanks! One other question for this install. There is no mention of a parking light connection. Is it assuming I will make the connection or like many newer vehicles is it activated through the CANbus?

There is a tech document on the park lights for that vehicle if I am not mistaken.

I removed the driver kick plate and have looked through the harnesses but I can't find these wires. There are a lot of harnesses and they're very tight. I'm posting pictures of what I'm looking at.

This last picture looks similar to the one from Directwire but I can't get to the harness behind the BCM.
