skongolf Posted September 14, 2009 Share Posted September 14, 2009 I am getting ready to install a new Tail light module for towing on our 99 RX since the stock one is blown and I am trying to find out if it is a 2 or 3 wire system. If anyone had done this I would appreciate the input on the installation. Also, does the stock tow wiring harness (plug going into the module) have a dedicated wire going to the battery or will i have to add one?
