I have posted this on transit custom forum but no answers yet so thought I wold try on here !

After 3 months of ownership the 14 plate Transit Custom Double cab Limited spec needs a tow bar fitting I can sort the spannering side but the electrics are causing me to scratch my head had a quick search on here but could not seem to find a definitive answer..

I have procured a custom loom, canbus type, 7 pin trailer connector from ebay believed to be OEM Part.

I Fitted one to my Cmax a couple of years ago and laying the wires in the boot it was quite obvious that in 'Interfaced' to the car in the NS boot so no major problem working this out.

So the Transit tow bar loom is about 18 foot long so could just about reach anywhere !

Q1 where do I terminate the Ring Earth
Q2 where does the Green can bus connector connect
Q3 where does the 12V + feed connect to
Q4 where does the wiring Gromit pass through to the underside of the van

Any help appreciated or points in the right direction

Thanks in Advance Agriv8
