1989 Nissan 240sx Radio Wire installation?

i have a 1989 Nissan 240sx and im trying to install an aftermarket Pioneer radio (DEH-P20), my car only has 2 speaker which are in the front right and left side doors, i've gotten many wiring diagrams to help me install it and im pretty sure i have connected the wires correctly. the only problem is that after i got done connecting it, the radio wont power on.. if theres a defective power wire, what can i do to fix it? and also, where EXACTLY do i connect the Ground wire? oh and why does the car wires have multiple same colors for example, theres like 3 light blue wires non striped from the car, etc.?thank you

Answer:

I think the problem you are having is that your system is an active system and you don't have the power antenna wire connected to the amp turn on wire. Without this connection you will not get any sound. So what you need to do is connect the amp turn on wire to the power antenna wire. The amp turn on wire for your 240sx should be light green and located on the smaller of the two molex connectors of your radio's wiring harness located in the dash. Just connect that light green wire to the blue power antenna wire on your new radio wiring harness and you should be good to go! As for the ground situation, as long as you mounted the new radio to the metal brackets originally attached to the Nissan radio it will automatically be grounded when you screw the brackets into the dash. I hope that helps, if not give me a jingle and I'll see if I can't clear anything up for ya.

Hello, I too are having a problem with the radio on my 90 240SX. The old radio was working but it did not have a cd player. So I bought another radio and wiring harness and connected everything. But the problem is there is no power to the new radio. I checked the fuse uner the dash and it was OK. So I plugged the OLD radio back and now even the OLD radio does not have power. What is going on? Please help.

The Nissan 240SX (as it's known in America) is based off the Nissan S platform, the same platform that was used for all years of the 240SX, and was used for all the Nissan Silvia's as well. All vehicles built on the S platform are rear wheel drive. =]
