Hi, this is my first post. Normally I search and try to find answers to my questions. This site is very helpful. Anyway, I hope I am posting in the right place. Here is my problem. I have recently installed an old CVA-1000 (not meaning this in a bad way to anyone, but this is the first in-dash mobile video screen that alpine made for those who did not know). I bought a wiring kit to fit my 04 350z. I have the the non bose, non navigational hu. When I hooked up my CVA, and turned my car on, the service engine soon light came on. The ironic thing is, the CVA-1000 works fine, no problems at all. I checked all my grounds, there ok, no exposed wire. What I did notice was that the oem hu had 3 plugs but I only needed to use one. Could only using one plug cause the service engine light to come on? Any help would be appreciated.
