i'm just wiring in a engine loom, and ive got green wire for tacko. red/black for fuel pump, red/blue 12v from batt, ive no earth at the connector, i do have a black wire which it says is a sw live but i'm get a earth coming down it? there a earth on the inlet and ive add one on the loom scart end so i guess it doesn't matter that its not earthed at the plug, i have had it running when i bridged the ecu relay, but i'm worried about connecting this black to a ign live?

has anyone connected one of these up fresh that can remmeber the wiring...

cheers

the loom should be earthed on the inlet, this is the ecu earth, and should never be earthed anywhere else do to it picking up signal noise

red/blue = perm live, black = ign live, black/red = fuel pump live, green = rev counter, brown/white = temp gauge, earth is normally 2 ring connectors mounted to the top stud of the throttle cable bracket.
