Hey, I also just picked up a '22 billet silver big horn. the thread confused me on part numbers between 19-21. I'm looking to do a plug-&-play set-up as well. Do you mind sharing witch part numbers you used to order?About $230 in parts from BAM Wholesale, $130 for Jimmy07’s wiring harnesses, $50 for the AlfaOBD software app, $25 for Security Bypass and $20 for OBDII Bluetooth/WiFi…total about $450.
