Gwolf3 - Wow!!! Thanks for the prompt reply! I am pretty green to anything electrical as well with audio systems. I am looking at a different HU (Sony or Pioneer) and will be putting a small Amp over in or near the OEM location and see that harness adapters are pretty short. Would I be purchasing a few to daisy chain over there or find a wire kit to just splice in to get the length? Wondering the same thing on the RCA Extenstion - find a longer one if needed to covert the distance. Lastly - did you install that Pyle under the panel in the rear OEM location or just under the seat? Thx!!!
