Hello, Can anyone out there help me? I have purchased a new Alpine cde-151 am/fm/usb radio and a set of speakers for my 1990 Suzuki Carry Truck but I don't know how to install all of it. I was told that there is no adapter harness for the truck. I have looked all around for threads on how to install a new radio, but I haven't found anything that is specific enough to instruct me on how to do this. Can anyone tell me in detail about what they did to hook up the new radio? tanks in advance.
