I installed the Canadian harness in my 2019 sig. Completely plug and play, except for 1 wire that needs to be moved from the OEM harness into another slot (takes 20 seconds).Am I reading correctly that the Canadian harness is straight plug and play? No splicing and no running a wire to the battery? It would be on a brand new 21 Signature so I like if something goes wrong I could just unplug/ remove that harness and not mess up my warranty
And as far as receivers I'm thinking Curt or Etrailer class 3 which I understand are the same except Curt is gloss and Etrailer matte. Any guess if one is more rust resistant than the other? I need to deal with Minnesota winter road salt.
Neither the Curt nor DrawTite (or any hitch for that matter) is completely rust-proof. They are all powder coated from the factory and all will inevitably show signs of surface rust after use (I feel your pain, NJ salty roads are a bear to deal with). Once a year I give my hitch a brush and hit it with some rustoleum. A bit overkill, but I want to keep the gloss black look.
