If you get a HU with pre amps all you have to do is make a wiring harness (if you can do basic wiring) for my 89 it was the same wiring harness as the non bose, you just need to run the pre amps insted of the speaker level output thats all the box does in the pic (it drops the speaker level to a pre amp) then all you have to do is hook the amp turn on lead to the harness for the amp turn on (usally a blue and white wire) what i did is pull the bose HU out, took a muti-meter and turned it off and on while checking what wires had power. As for the RCA ends i went to radio shack and got them, it's hard to get a good splice using RCA cables due to most of them are shielded and are thin wires.
