Mid Ameriaca motorworks sells the ones that are correct color-keyed like the factory harnesses.  West coast metric was their supplier, don't know if they still are or not.  You might check with them too.  Personally, I'd suggest staying away from the universal "buggy" type harnesses most of the budget places offer for sale in the mag. ads, if you're not highly skilled in the wiring department. The factory style go in much easier and don't require the "cut to fit" method.
