Just thought I would post this up as I could only find info after much trawling of usa sites and they didn't seem to tally. So if anyone should need it it will hopefully save a bit of time. The Harness is a Newbonnieville one bought through Squaredeals I was adding Shin Lo Arizona indicators and Lucas 525 style tail/stop lamp The plug'n'play harness coding is as follows: Main Block brown : rear right indicator orange : rear left indicator dbl black : indicator earth dbl red : for use if using indicators as running lights, USA thing I think. Tail Light Loom blue :brake light red :running light Black ring : earth* *earth has to be connected to the tail light, I attached a wire between tail light and tail tidy and then earth to that wire to keep the loom under the seat. So connections are: left indicator wire in (my case Black/White) to Brown then Black (earth) to dbl black Right indicator wire (my case Black/White) to Orange then Black (earth) to dbl black Tail light In my case black was the stop light and red was the running light so black to blue and red to red. If you are using the front indicator plug'n'play harness Mine worked like this Front right: indicator Black/White through harness to black/white and indicator black through harness to Green/white. Front Left : indicator Black/White through harness to black and indicator black through harness to Green/Brown
