Hello all,

I, like many users have been using http://www.courtesyparts.com/ to find, price and order parts for years.

My wife owns a 2007 Titan and called the local dealer to order a tow package and did not mention the part number, 999T5-A6000 from courtesy.

I received the invoice and they sold her a 999T5-WW300. What's the difference between the 999T5-A6000 and 999T5-WW300?

Also, will I still need the third relay 25230-79944?

Thanks in advance!

***EDIT***

Looks like the A6000 is a Class III and the WW300 is a Class IV.

Titan's with the Tow Package come with the class IV hitch. I thought that the hitch from the dealer came with the relays.
