My cousin had the factory sub from his 04 Lariat kicking around his garage for the last couple years and gave it to me. I checked and I do have the harness under the rear seat but I don't have the Audiophile HU. The part number on the sub is 4L3T-18C804-BB. The PN on the amp is 2C6F-18C808-AA. Assuming I get the right HU, will this sub work in my truck? Have the wiring harnesses changed over the years? Can someone who has an 07 take a look at the part number on their sub? The reason I ask is the sub has 10 pins in the connector and my harness only uses 5.
