WHen i installed my KNA-DV4100 unit along with the 7015 double din screen, i tapped the speed wire from the harness in the guage clust. The pin i believe is 2nd from the right on the BLUE harnes. It should be a stripped green and blue wire or green and black, i know it's 2nd to last pin, but you can check it with a volt meter by hooking oneend to ground, and the other end to the wire, set it on volts and jack up the front wheels. then when in nutral, spin the wheel. it should pulse the wire indicating speed. I found out from this system that my car is 5 MPH slower than what my spedometer is telling me. As for the reverse wire, you can get it from 2 easy places, 1) the shifter area allthough, those might be ground wires and you need a +12V, or 2 you can get it from the trunk area near your backuplights, which is where i got mine from.
