Had the kit on and working for 3 years. Now all of a sudden no power. I have verified the 10 amp fuse is fine( hard to access) so.... what am I missing? Brown relay Maybe?
Skibane...FYI...Nissan DOES offer a 4-pin tow package connector for the Frontier..... Part #999T8-BR004AFAIK, Nissan doesn't offer a towing package with a 4-pin connector for the Frontier.
Are you using some sort of 7-pin-to-4-pin adapter?
