I have just installed a towbar on my hse and, rather than spend approx NZ$100 for a complete wiring harness, I bought a pack of pin terminals and a plug and made my own - $12.50.
I was told specifically not to just hook into the wiring loom as an auto sparky would but use the plug - other wise I could have ´fault´ problems. The factory wiring loom has 7 pins - for L and R indicators, brake, earth and TWO tail lights. I am under the impression that both tail light pins must be used so I just put a 2 into 1 join and everything works ok - I even get a trailer symbol flashing on the dashboard in time with the indicators. And I have no faults appearing.
BUT there is one loom plug terminal unused and I have no idea what it is for - it is red with an orange tracer. I have checked and it does not seem to be related to the reversing light circuit. Maybe for electric trailer brakes?
Can anybody cast any light on what this extra wire is for?
Cheers
