Neither do I, it's called a loan. haha But I can understand if you don't want to go into debt for a new car. You own your Accord, right? I love not having a car payment...that's gonna be a hard adjustment the next time around.
The other three are easy or should be anyways if you at least have power mirrors. You only need to worry about the two wires which both look black when I look at mine. If you need to wire the other three well I dont know what to tell you. Best to see it on one that has it and follow the harness.
