Hey guys, I think this has been asked before but here goes.
On a 2011 Hilux D4D, behind the speedo cluster on the main plug pin 5 is the speed sensor wire (pink n blue). My question is what is the pin 6 wire (purple n red)??
Is that a ground or earth wire of some sort?
Any help would be much appreciated.

On the site somewhere are the pin outs and cable colours. Have a search for rear camera install around that era. Its over 12 years since i did mine but i think its a reverse wire

Thanks mate will do
