you are right, the front three just under three coil. but the rear three don't look like that, you just simply trace the cable from the plug in the front you can find the rear one. there are only three ignition coil, one control two plug but you have to be carefull. if you don't disconnect the battery, you risk damage the pcm, but if you disconnect the battery you have to know the code to active your radio.
