CAPKELLY Report post Posted April 14, 2014 Hello. I am buying a 2013-2014 GMC Terrain. When setting up the wiring on this Toad is it simple or I have heard about separate tail light bulbs? Right now I tow a 2008 Jeep Wrangler and no separate bulbs were needed? Any thoughts on this would be appreciated. Share this post Link to post Share on other sites
hermanmullins Report post Posted April 14, 2014 KK you do not need separate bulbs, just the wiring kit that has the diodes (4 ea.) and the harness. It is a very easy job and no extra bulbs or drilling required. You can get the kits from most RV stores, I know that Camping World has them and the diagram is very good.
