Wrong forum I’m sure. But maybe someone with knowledge can help. I’m installing new Pioneer FM in 2000 Freightliner. Radio has a remote. Instructions say to hook blue/white wire to the auto-antenna relay control terminal. I’m wondering if my Truck has an AARC terminal.It also says I can buy a hard wired remote control adapter and just plug it in the back. I’m guessing I need to buy the adapter. Anyone know anything about that stuff? Thanks any info appreciated
