So I recently purchased a Pioneer FH-S501BT to put in my 2008 trx4 Ram 1500. This is the first time ever installing a radio and this radio should be easy to put in but I am at a crossroads. What I want to do is buy a wiring harness to wire onto the harness that came with my radio but have no idea what to buy. Whenever I think I found one I look at the reviews and it says it’s not capable even though it says it is on the website. I am very frustrated and came on here hoping for some answers. I already have everything I need except this wiring harness, this includes the dash kit, and antenna adapter. I’m very frustrated with how difficult this very easy task should be. If anyone has any product that has worked on there 2008, 4 speaker system that would be a tremendous help. Keep in mind I do not have any fancy accessories such as steering controls, etc. Because of this I would like to stay away from installing an interface since it’d be unnecessary.
