I have a 2000 accord with a cd/radio player with steering wheel controls, P/N S39101-S82-A230-M1, but I needed a cassete player, so I bought one on E-Bay, CD/Cassette/Radio P/N 39101-S84-A510-M1, it was out of a 2002 Accord, but the steering controls didn't work when I installed it, so I bought another one on E-Bay thinking that I bought a bad one, but the steering wheel controls still don't work. The pin out on the back of the radio's are the same. Is there a difference in the steering wheel wiring on the 2002 ? Can I modify the wiring to get it to work? I tried putting the original radio back in, the wheel controls still work with it.
