Answer to: Mazda 5 rear left light assemblyYou must unscrew the panel on the inside and undo the bolt hidden under the square cover. This is much easier with 2 people. Now get a decent flat tip screwdriver and gently place the tip behind the cover. Now gently pry it back and follow the cover around. I undid the top of portion only. Had my wife hold it back while I squeezed my hands into the space. Use the same screwdriver to depression the clip on the wire. Once that's undone pull off your old broken taillight and fish the wire threw the hole. Connect the wire to the clip. I had my wife get the keys and do a test before I closed every up. Closing up goes alot faster. I used the flat tip screwdriver to flip the rapper seal over the plastic cover. You will have to use some force to get the cover back on. As you know it secured well and u must get it back on. Hope that helps. Pain in the butt!
