I used the harness for about 4 months before I totaled my car. It's from Vega and has the resistor put inline to take care of the jumping tachometer issues some OBD2b vehicles have when converted to OBD1 (mine had this issue before the resistor was put in).

I'm in Orlando, so shipping is probably easiest. The first person to PayPal me $50 at dontevenworryaboutit@gmail.com gets it. $45 picked up.
