I bought the trailer harness kit from Rovers North and have read the detailed install instructions on this site (https://www.rangerovers.net/outfitting/towing/lm/harness.html), but my 2007 SC has a different white connector that the single red wire from the new harness is supposed to be insterted into. Also confused as to why the kit has 2 relays (one 4-spade and one 5-spade) when the only port on my board appears to only have connectors for the 4-spade harness. If anyone knows the answer to these 2 questions or has a trailer harness installed and could take a couple of minutes and pull the access panel on the rear-left side of the truck and take a close-up showing (especially) the position of the red wire for the trailer harness I would be grateful!
