right, just given rodders the low down and thought id copy the list over to here. basiclly, on the wiring looms, theres a bunch of wires that comes from the main engine loom and connects to the car loom, these are all the wires you need to connect into the fiesta loom! theres a plug there so if posible, chop off 3" or so of the donor cars wiring loom and solder the plug into your fiesta loom, this will enable you to remove the engine loom complete from the car for whatever reason.

the wires on that plug and what they need connecting to are:

black/green = ignition live
brown/green = water temp gauge
black = 4amp ignition live
brown = earth from fuel pump *RELAY*
red = 4amp perminant live
brown/wite = earth
green = revcounter (the revcounter should work as normal with no messing about)




if you want to make youre own fuel pump relay circuit, its easy! get yourself a relay from halfords or wherever. itll have numbers on the pins which you need to connect up as follows:

87 - perminant live (from battery 30amp fuse if using erst pump)
86 - switchable live (ignition live.....from ignition)
85 - earth (to the brown earth wire mentioned above)
30 - accesory (to fuel pump)

make sure that the fuelpump hosuing isnt in anyway earthed to the car as this will blow the fuse and the pump wont work! ( :oops: )

you should always use an inertia switch when running an electric pump, you should put this somewhere in the feed to the fuel pump and screw/bolt the inertia switch uprght to the shell, then you will need an earth from the fuel pump to the chassis.

aswell as these wires theres one or two earths in the main engine loom that should be connected up to the shell.

do all that and you should have a working zetec loom!


**the list of wires above are from an escort loom, fiesta and mondeo looms MIGHT be different**


mods wanna chuck this in the FAQ section?
