Hi,
for model year 2001:
Blue with the red stripe goes to the reversing light bulbs.
Black with the blue stripe goes to fuse 29 (15A) in the main fuse box. This is the +ve feed.
from model year 2002:
Blue with the red stripe goes to the reversing light bulbs.
Black with the white stripe goes to fuse 29 (15A).
The +ve feed wire changed colour in MY 2002.
regards
Andrew
