i've managed to track down one of those manifolds pictured above too, should be on it's way to me soon , also i've found a suitable upper timing belt cover as well

all i need is the plastic water housing off the end of the cylinder head, there was one at the breakers yard today but i broke it getting it off somehow, they can't cost much new anyway

i hope the diagram above makes sense to somebody... i drew that last night when i couldn't sleep

Does to me

Does to me

you may notice there is no MAF or MAP sensors, i'm going to use the emerald in 'Alpha-N' mode whereas it gets main load signal from the TPS

Wiring Loom from mk4 golf gti 2.0... 99p from ebay

the first thing i've done is strip off all of the coverings/split tubing/insulating tape so i'm left with bare wires, this is a horrible long winded and filthy job

next identify which sensors are to be used and cut them off the loom and kept as much wire attached to the connector as possible... another thing worth remembering for reference is that there is no soldered joints in this entire loom, they are all crimped, including the splices:)

top left : Coilpack

top middle : fuel injector loom

top right : crankshaft sensor (note the use of shielded cable )

bottom left : Coolant sensor

middle : oil pressure switch

right: throttle body

felicia loom stripped and ready to meet the same grizzly end as the golf loom, i only need 3 connectors from this loom,

immediately to the right of the main ecu multi way plug is the wiring plugs which connect the engine loom to the dash/fusebox loom

these connectors mentioned above are located in the front scuttle to the right hand side of the battery

here's a detailed description of what the engine loom to dash/fusebox connection is doing

6-way connector

1: Switched Live (Red) - becomes live when the ignition switch is turned on

2: Fuel Pump Live (Red) - is live whenever the fuel pump/relay is live

3: Fuel Pump Control (Black) - the ecu shorts this wire to earth which activates the fuel pump relay

4: Rev Counter (Black with green tracer) - the ecu pulses this wire once per engine revolution

5: Temp Guage (Grey with red tracer) - signal from coolant sensor to the temperature guage, very strange signal, always reads a negative voltage

6: Permanent Live (Red) - allways live.

3-way connector

1: Ecu K-Line (Grey) diagnosis/immobilizer connection

2: Oil Pressure switch (Black) - the oil pressure switch earths this wire to the engine block when a pre-determined oil pressure is reached which turns off the light on the dashpod

3: ABS Light (Yellow) - if there is an abs fault this wire goes live which lights up the abs warning light.

note: the wiring colours are not allways the same on all models and often there will a splice in the loom which changes the wiring colour, but the function of each terminal is still the same

i've abbreviated the felicia loom

on the left is the lambda sensor wiring plug which i'm going to wire up the wideband lambda reader harness that i've already made below

Tom, when it comes to it and im sorting the Emerald wiring out on mine mind if I pick your brains? I'll be running K3 also as my M3DK can be redone to the new spec.

yeah no problem, the m3dk and k3 spec ecu's are plug compatible anyway, it's only the software that's different

I got the ECU diagram; it's way clearer than anything Haynes have done recently.

right, next thing to do i draw up a diagram of what the loom actually physically needs to look like..

almost there

Looking very good Tom

Looking very good Tom

so does the loom!

i've got no black electrical tape left at the moment so i'll see if i can get some form the petrol garage later when i go out

well that's the loom done and dusted

just ordered in the bits i need to make the remaining part of the engine mounting as described earlier on in this thread, came to just under £20 including delivery, should be here tomorrow.. then i can really make a start in trying to get this thing working/running

Wow I'm getting excited!!!

Great work!!!

looks like the mk3 golf fuel injectors aren't going to fit, they fit on the fuel rail ok but they aren't long enough to seat fully into the intake manifold, i wandered up to the breakers yard to see if i can find a solution... i think i might be able to use the injectors from a rover k-series engine instead:O

Maybe the wrong model of Golf injectors?

Or K-series units are fairly popular with a variety of tuning and special applications.
