I'm looking at nokya headlight harnesses on ebay and other generic harness on ebay because I have a few friends that want to put in some nokyas and I know the factory harness needs to be upgraded. They are H4/9003 bulbs.

It looks like all they are are 3 strands of 14 guage wires connected to a HB2 male connector and HB2 female connector. Is this correct?If so, this means I can either get 3 dollar pigtails from autozone and go to radioshack and get the opposite end HB2 connector and connect?
or get 2 HB2 male connectors and 2 HB2 female connectors and 3 strands of 14 guage wire and put it together correct?All parts found at radioshack. Is this all that these 25 dollar harness are?does the 14 guage wire need to be a specific length?Thanks.
