Rover V8 Hotwire Efi Wiring Details

Post by Coops »

http://www.v8forum.co.uk/images/forumim ... twire3.jpg

This is the Rover efi (Hotwire) wiring details and colours:
(this is a basic setup to run the car, i have not added any of the speed sensor wiring etc as mine runs fine with out these inputs)

Brown wire goes to battery live +,

White goes to Ignition switch live (ONLY live when in run position),

Purple/white is + feed to fuel pump,


In engine bay there will be a single black/white wire usually with the airflow meter loom, this has an inline resistor MAKE SURE THIS IS FITTED (maybe in the loom next to the ecu), this then goes to the negative side of the coil for efi ignition trigger this is to tell the ecu that the engine is running and to fire the injectors,
Two black wires with ring tags on, these MUST GO TO A VERY GOOD EARTH !!!!!!!!!!!!!!!
Some cars have a stud on the back of the passengers cylinder head for the earth tags,

ALSO if using a manual gearbox you will need to earth the orange/black wire via a 510 ohm resistor,
