Hi All

I purchased a Windsor 5.0l from an Au from marketplace not long ago. Unfortunately I have been left scratching my head around what I have exactly. I receiving the motor, engine loom and wiring plus ecu.

My plan is to put this into my XF.

I was told this was out of an XR8. I got the engine number and called Ford, they reckon it’s out of a Fairlane. So this was my first disappointment.

I started checking some other things and noticed the ecu. I searched the number and it has WANA at the top. Checked online and it appears this a 6cyl ecu…

I am now worried about the harness that I have as well as the additional wiring I have which includes the fuse box.

My question is how can I tell if my loom is from the 6cyl or v8? What are the differences.

Also on the loom that goes to the fuse box, I can confirm it has a 3 pin plug that goes into the alternator. I have heard the v8 has a different alternator? So I would assume this loom is ok?

However the loom that connects to the engine with the red plug and goes back into the ecu, I am worried about this one

Appreciate any assistance.

Note: I have gone back to the owner but have not received an answer so far

you need the full number from the ECU.

it 'should' help you workout what you have.

Hi, thanks for your reply. Yeah definitely know the ecu is not for this engine based on the code.

My problem now is the wiring harness. Eg what are differences between a 6cyl and 8cyl ecu harness and how can you tell the difference?

sorry but that i don't know. other than the coil for the 6 cylinder is mounted down near the passenger engine mount.

The V8 Harness will have the MAF plug for a start.
6cyls are Speed density and therefore don't have a MAF.
What is the catch code on the EEC connector? it's a 4 character code like for example; 12RB.

F5SB is the 4 digit code.

Its definately a V8 harness from what I can see. Thanks for the top on the MAF sensor.

F5SB is not a catch code I've seen before but I read your first post and you said the code is WANA. If this is a 6cyl code then it's likely all of it is from a six cylinder. Apart from the MAF connector you with also have a U-shaped engine harness with 8 injector connectors instead of a straight harness with 6 injector connectors.

It seems WANA is a six cylinder Futura EEC.

BTW what do you mean by a series 2 Neo engine?
