if you buy the wiring harness, metra part number 70-1677-1 you should just have to match them up. the second (small plug) goes into the small plug ght will be behind the cig lighter. just make sure that the orange is plugged inline with the yellow in the harness,

if you are gng to hardwire it, let me know, can give you the exact connections(not recommended)
