98 Es300 Car Stereo Troubleshoot
 

I am trying to install an aftermarket stereo on my 98 ES300. I was told it should be relatively simple, and purchased the wiring harness and dash mounting kit. I got to the wiring part and was faced with my first dilema. The wiring harness provided only used on of the remaining connectors. I was unsure if that meant I needed to cut off the remaining connector and manually wire the remaining connections. I wasn't able to get any power to the new radio using just the wiring harness connections. I decided to put things back till I could figure things out. I put back the factory radio together, but now I can't get any power to radio at all. I have checked the fuses, all seem ok. Any help would really be appreciated.
