does anyone know will the led tailights from the 2006 model work on an older model?

Can't tell, there should be two plugs on the back of the LED taillights. Those two plugs should plug onto the taillights where the older models have two bulbs. Check it out first.

Check VERY carefully as voltage is likely to be different for LEDs than for standard filament bulbs!

^ That shouldn't matter since the older model is already LEDs.

I bought a set on ebay and they fit perfect on my '03...LOVE the LED!!
