Does anybody know what the differnces are between 98 and 99 head units? Crutchfield said they used different kits but was not able to give me specifics.

99 XLT 5.4l reg cab 2tone 3.55 gears eclipse cd player. subs coming soon

 

I know for a fact that the wiring harnesses are different because the guy at best buy showed me the old and new wiring harnesses. I also know that the speaker plugs are different too, cause i wanted to use pre wired hooks so I wouldn't have to cut wires on the speakers, but I had to anyways. I don't know why they are different though, I jus tknow that they are.

 

The 99 is also double din instead of 98 din and half.
They also use different mounting adapters
