Product description was ok, installation is not hard and it works as presented. I tried to find out some technical details from the seller, unfortunatelly he or she wasn't able to properly provide. One remark: this module works for Sedans (at least from Toyota) without any power lifters, because the trunk door of the Sedan has springs that pop it open once the module sends the open command.
in tail gate lift box, correct items confirmed with instruction. thank U-!
