Hi Everyone, haven't asked anything on here in ages but I'm trying to put a new/old Pioneer DEH headunit in the sons VZ crewman. I have attached a photo of the plug that came out of the VZ and it only has 4 solid color wires plus the blue aerial. I have looked at the wiring diagrams in here and the only reference to red is constant +12v output, on the actual wire it is printed 12volt ingnition switched and the yellow wire is for accessory +12v. Diagram says Orange is battery +12v. I'm getting confused between constant +12v output and battery =12v.
The Pioneer plug only has 4 wires coming out of it, a yellow which has a +battery label on it from factory, a red wire which has ACC on it from factory, a blue which has System Remote Control label from factory and the earth. Any help would be appreciated as he is out in his car so I can't test anything at the moment, just confused because the diagrams here have 2 colors in some of the wire sections where mine are all solid as pictured.
