Oh shoot I forgot this even existed. Yeah I deleted that video decades ago. Basically it was this: Step 1: Add your desired vehicle to the LCPDFR "additionalvehicles" or whatever line, to give it access to LCPDFR functionality. Step 2: Add the same car into ELS.ini copying the same format as the other vehicles listed to give it sirens and lights. And for the more advanced users who actually want to literally create their own custom vehicles and turn them into police vehicles, like completely recognized as such if the above doesn't work for you, then look towards this tutorial. It'll explain the process. But note: It isn't fast and really only is for advanced users! You've been warned!!! http://gtaforums.com/topic/420911-add-new-car-gta-iv/ Then after you've added the new car following the tutorial above if you chose the advanced way, simply follow my original first two steps again to give it police attributes and access to LCPDFR functionalities! I hope this helps! I tested this on GTA IV and it works fine, not sure about GTA: TLAD or GTA: TBoGT though! Good luck!
