Mapping ELS to a controller

[tehherb 0]

I'm using a PS4 controller with x360ce to play GTA and i'm having trouble mapping the sirens and lights to buttons. Is there a way to tell what button number I need to map to, I've been using the button numbers x360ce gives me for each button to no avail.

Without external tools, it's impossible to map ELSv8 to a controller sans Express Mode. For more information about Express Mode, consult the user manual.

If you have spare buttons on your controller, you may wish to set the ELS keys to some keys you more than likely will NOT use in normal gameplay, then map the free button to it.

Because I do not personally use external tools to map my controller, I cannot further assist, however.
