RRC V8 auto to 300tdi manual, speedo wires?

Afternoon all can anyone shed some light on wiring up my speedo, it used to work off the speed transducer I beloved when the auto was in, now the r380 in it has two wires coming out of a plug in the transfer box, ones brown and red and the others green and yellow, does any one know where these wires need attaching to get the speedo to work?
Many thanks, Gareth

i think your r380 must of come from a discovery the yellow is the feed to ecu green is the live feed from the fuse, i will check the other ones in my dad discovery book
