Basically find any car like ford to ISO or toyota to ISO, cut off the toyota bit or the ford bit and leave the iso connector. Strip your wires from the car (constant 12v, accessory, dimmer and earth) and solder that onto them, heatshrink up the soldered join and buy a clarion to ISO cable. Click in the clarion cable to the iso cable, click in the head unit into the cable.
The benefit of this is when you go to sell the car, and you want to reuse the head unit on the next car, pull out the 1000 dollar clarion head unit, and put in a cheap 100 dollar pioneer head unit instead. Buy a pioneer to iso cable and swap it over in seconds. It's worked in the past for me, when I've had to replace head units that have either died or swapped them out between cars. It also looks much neater.
