Thank you. I thought I wasn't following instructions. The instructions are excellent until they tell you to put the canister inside the skid plate... Then your on your own. I still have two 90s I don't know what to do with, and some zip ties to replace the broken hose clamps... Jeez. What a PITA.The straps hook into the slots on the side of the skid plate. The idea is to keep the Evap Can secured inside the skid plate. You only want to tighten the bolt enough so that holds your Evap Can in the skid plate. If you over tighten you can cause damage to the plastic Evap can and defeat the purpose of protecting it. Hope this helps.
