I purchased an RES kit (PT398-0T090) online to install into a 2010 Lexus 250h. The kit did not come with installation instructions, however, a Google search found a PDF that was formerly hosted on a Sewell dealer website (it has since been shut down). Does anyone have the installation instructions for the Remote Engine Starter for this year and model? I know I can take it to the dealership, but I'm mechanically inclined and would like to take a whack at it first. Thank you for your help...
