Gents,

Recently I've purchased a new keyless entry setup to install in the car. I've got it working right now but I just don't know if this is the correct way of doing it or not.

With the image from above (hopefully you can see), I've got the white wire (closing signal) connected to the G-R wire in the car for LOCK. I got the white/black wire connected to R-W for UNLOCK. I then took yellow & yellow/black and connect them both to the ground. Is this the correct way of doing it by taking them to the ground? or am I supposed to tap those into something else?

thank you for the assistance!

It would appear that your car has Type B locks. These require a (-) pulse to actuate. The way you have it wired is correct.
The White COM wire is the lock relays' output. You supplied it with a Chassis Ground at the Yellow input wire. This will cause the White COM wire to output the correct (-) pulse when the aftermarket RKE system does a lock. The Orange wire is not used in your application and should be insulated. The same applies to the Unlock portion of the RKE system using its' ???/Black wires.

Hello Kreg,

Awesome news! Thank you so much for the clarification, I can rest now haha. How are you able to tell that it's a "Type B" locks just by looking at it? I'm still trying to learn and get better with car schematic diagrams.

Greetings,

If you are new to the 12 volt auto arena, you will need this document from Directed ( DEI ). It goes into detail explaining the various types of power door locks used in the auto industry.
Here is a link to that guide : https://www.the12volt.com/installbay/file.asp?ID=708

For the aftermarket installer there are several sites that provide vehicle wire lists to make things easier. Bulldog Security is still available but hasn't been updated with newer vehicle since ~2016.
Here is a link : https://www.bulldogsecurity.com/bdnew/vehiclewiringdiagrams.aspx

This site also has good info on vehicle wiring, relays, diodes and door lock systems.

Enjoy!
