I have a 1987 740 sedan. The previous owner had an aftermarket radio in it. I recently obtained a volvo radio for it and was want to get a wiring diagram before I went to install it. Does any on know where I can get one?
Thanks in advance

thanks jon

 

jon: Thanks for the diagram it was helpful. I got lucky and the previous owner did not cut out all the wiring to the amplifier. I got the power to the new radio but no sound. I could not find a blue wire or a white wire under the dash or any that we not attached to connect to the radio. Mine is an 1987 740 so I wonder ifthey are a little different.
any help is welcome..
