I have been researching the trailer hitch for my 2001 V70. I decieded to go with after market hitch (a Draw-Tite) which was significant cheaper the the dealer item (< 0). The question I have is about wiring. DO I go with a after market wiring kit or do I get the OEM. Does the after market kit require cutting and splicing wires. If I go with OEM does anyone know how much that will cost? Also, I noticed that some 2003 XC come with a class II hitch (it looks like it has a 2" post not the 1 1/4). Does that mean that the OEM version is stronger? Or can the 2003 XC pull more?
