Do they make em for that? The pump connector is below the manifold between the FI pump and the block. Just twist and lift off. Your loom should have two plugs for this connection one that goes into socket, one that then receives plug you just took off.

The plug should only go in one place you can't put it in wrong. Or at least you should not be able to if the thing is any good. You won't see it from under car i can assure you. The connector C1502 has seven wires. Red/Yellow pin 1. Black pin 2. Purple pin 3. Blue pin 4. Brown/Green pin 5. Grey pin 6. Red/White pin 7.

Do the plug and socket you have on your unit match that plug? If it does that is the correct one. There is only one plug and socket like that on the entire car. The connector C1502 is under inlet manifold between injector pump and cylinder block just above where injector pipes come out of pump.. If it plugs into your new unit what colour the wires are is a sick jumbo.

it say's to connect plug to map/boost pressure sensor which is above the fuel filter then connect two wires to connection pin wires 2-violet and 3-brown or black then under that in red writing IF ALL WIRES ARE BLACK YOU ARE ON THE WRONG SIDE OF MULTIPLUG might have to contact seller thanks again for your help Andy

Yeah i know but i have told you which colour wires go to which pin. Pin numbers will be on plug just connect the wires to the black wire that corresponds to the correct coloured wire going into the socket. There is no violet wire. Pin 3 is purple. To get at them properly you will have to remove the inlet manifold.
