Just finished the install of PL8521 on 2013 DCSB, piece of cake
. I got mine off amazon
for $77 even though it said it wouldn't fit a 2013. Also, as other members have posted, my unit has a black housing with a silver mounting bracket which also included a block of closed cell foam attached to the underside. I was surprised to see the foam but it just meant that I didn't have to swipe one of my wife's kitchen sponges to be used as padding. Guess P&L caught on?
The Radioshack Tap-in squeeze connectors (~$3 for a 10 pack) are a lot better than the ones that come with the kit. This is a good tip from the op.
Now if they would add a second mounting point to the current single bolt design. I ended up using loctite and a lock washer on the bolt to secure the actuator.
Has anyone seen a mod to add a second mounting point for these locks?
