I am selling my Bestop underseat security drawer for the 07-13 JK this was in my '12 JKU for 2 months and I paid $65 shipped from the vendor. Its heavy so shipping will be a bit but I can use my fed-ex account to keep the shipping cost reasonable.
Asking $40 plus shipping
It will fit the 07-10 with no issues at all and based on my experience 11-13 will need to unbolt a little bracket that holds a wire clip in place. Once you remove this bracket you just zip tie the wire to the bottom of the seat and your done. The bracket serves no real purpose other then to hold the plug, the instructions even say to do the zip tie trick so it's not an issue.
I believe these will not fit the JK that has a flip forward drivers seat.
Please PM me if your interested.
