Lift mirror Accord 2005
 

Hello,

I'am from the netherlands and we drive a Honda Accord:

Honda Accord Tourer (CM/CN) 2.0 i-VTEC 16VCombi/o, Benzine, 1.998cc, 114kW (155pk), FWD, K20A6; EURO4; K20Z2, 2003-04 / 2008-07, CM1

The left mirror is broken, also de case. I can find some secondhand mirrors but you can chose between 7 or 8 wires.
What is the difference between those two?

Thnnk you!

Marnix
