Ford explorer stereo install
I have a couple questions regarding my 99 ford explorer. The stock CD/tape deck gave up the ghost. The stock stereo has steering wheel controls and DOES NOT have the disc changer. When I pulled the stereo out it says MACH on the back. It also has three plugs coming from the back. I do not know if it has the amp or not. However I am putting a Pioneer super tuner IIID. I have the wiring adapter from Best buy and it only adapts to the biggest plug. The other two smaller ones I have know idea on. Is one of the plugs for the steering wheel controls and won't need? Is there another adapter I need if it has the amp? Don't want to fry anything. Any help or advice is greatly appreciated!!! Thanks.
