I've got a double din DVD player for my vectra. Taken out the standard stereo. When I connect the stereo wires to the car, but it doesn't stay on. It's a continuous loop of ON/OFF/ON/OFF
Am I connecting it up wrong? I know about the red/yellow wires, live, ignition.. Tried all that.

I've got the PC2-04-4 harness adaptor (all it is, is swapped over live and ignition wires). Thats all the cables i have besides the stereo one.

Please someone help. It'll all look sweet when I've finished. I'll post pictures when I've done it.
