Review on 🔊 PAC ROEM-FRD2 System Interface Kit: Upgrading Factory Radio & Amplifiers for JBL/Mach Audio in Select Ford Vehicles by Michael Jenkins

FYI that might help. This works great in a 1997 Mark VIII LSC with a JBL OEM system. I used a JVC KD-X470BHS head unit and kept the factory amp (F5LF18C807-AA). I had to reconnect the 4 wires (Purple/Purple Black and Green/Green Black) to the black connector as instructed/detailed in the instructions. I used the "high level" inputs (black bars) on the ROEM-FRD2 since the JVC is 50W x 4 channels. According to the manual, the "low-level" inputs (red bars) are for radios up to 25W x 4 channels. Hope that helps.
