Hi ,I've got to replace an abs sensor on the rear of my focus st170, someone has been bodging before hand and has cut the wiring before the abs connection and has just joined the wiring together ,my question is ......

I've got another sub loom from a breakers yard to do the job properly but the wiring colors are different ,the original loom wiring is white& blue on one wire and green&yellow on the other wire .

The replacement sub loom from the breakers yard is white&green on one wire and brown&blue on the other , does anyone know which way around the wires need to go . Thanks in advance Kev
