16V CONVERSION...ONLY COUPLE WIRES TO GO...HEEEEEELLLPPPP !!

HI GUYS
ONLY A COUPLE LEFT TO GO….RED/YELLOW FUEL PUMP RELAY EARTH TRIGGER…WHERE DO I PHYSICALLY CONNECT THIS TO ??? CAR IS ORIGINALLY MK1 GTI….
BLACK/YELLOW..IDLE SWITCH FEED…AGAIN WHERE DO I PHYSICALLY CONNECT THIS TO ???
ASSUMING THE RED/YELLOW GOES TO THE THROTTLE BODY..WHICH PIN DOES IT GO ON…SEE ONE WITH A TSR LOOM THAT HAS A BLACK WIRE ADDED….ANY IDEAS….HAVE THE REST CONNECTED AND HAVE WIRING DIAGS IN HAYNES MANUAL BUT CANNOT MAKE HEAD NOR TAIL OF THEM…..ANY HELP APPRECIATED….TRIED RUBJONNY BUT GUESS HE MUST BE AWAY….

red yellow fuel pump trigger wire - Goes to the earth pin on the relay. The ecu controls this wire to activate and deactivate the fuel pump by providing the relay with an earth.

black yellow - Not sure where this physically attaches to, but when he throttle is closed this wire should see 12v. So presumably itll attach to the throttle body but i dont know for sure

HI
THAT MAKES PERFECT SENSE….HOWEVER WHERE DO I FIND THE EARTH PIN ON THE RELAY ???? WHERE IS THE RELAY SITUATED ???
ALSO HAVE NOW FOUND OUT THAT THE…..BLACK/YELLOW GOES TO PIN 3 (TOP CONNECTION) ON THE IDLE SWITCH PLUG…THEN RUN A WIRE FROM  PIN 2 (MIDDLE CONNECTION) BACK TO IGNITION LIVE FEED …( COIL)….APPAARENTLY THIS IS THE ONLY WAY YOU SET THE TIMING AT THE RIGHT REVS…..MANY THANKS…JUST WHERE I FIND THE RELAY EARTH PIN NOW…THANKS MATE

on the back of the relay in the fuse box matey
EDIT: Fuse box is in the passenger side footwell… but id hope you know that already haveing done most of the conversion
the relay is fairly big, and probably has fuel pumprelay written on it… i forget which slot its in exactly though… what youll have to do is take the relay out and see if theres any diagrams on it to see which pin it is, or get a wiring diagram to check wire colours, or use a multimeter and a piece of wire to to check voltages and hard wire an earth in to see if it works…

hope that helps

HI
MANY THANKS WILL GIVE IT A GO…
