the lom i have does include the ecu and relays! it oes under the seat on the rrclassic and the prob i was havin was the the conectin where this joins the interior loom.
there is a rectangular plu with 7 wires in, here they are and with what i think their job is,
white/green- ig switched 12v
white purple- fuel pump feed
black yellow- speed sensor????
brown- 12v battery feed
black orange- neutral parks switch
purpleyellow- front heated screen sensor
does this help? im thinkin if i conect them as above then it should fire up? the rest of the loom around engine has been left untouched, ie all wires fron/to ecu and all engine sensors such as air flow meter coil etc
