Fusebox wiring - question for the NA-TT chaps


Homer

Recommended Posts

I have the oposite problem to the NA-TT converts... TT fusebox and NA engine loom, now I get to that 2nd ECU plug issue where they don't match up.

 

I have a spare loom from a TT which I can chop into the NA engine loom, but am not sure which wires need to be connected.

 

In the pic below it shows the 5 wires on the TT plug, the 3 on the NA one.

 

1 & 2 seem to be the same as 8 (does 8 need to be spliced into two?)

3 & 7 seem to be the same

4 & 6 seem to be the same

5 is an additional wire that is not on the NA loom at all

 

Can anyone point me in the right direction?

I found this thread useful before i did my engine swap, a guy in australia put a tt vvti lump in his n/a and it shows in quite a bit of detail the process of getting around the wiring differences on the fusebox...

 

It's pretty long but look at pages 28, 37, 44, 45

Thanks Mike, had a chat with Jezz earlier and think we've got it sorted (Cheers Jezz!)

 

As it was an NA engine one of the black/red wires and the blue one are not needed. All it needed was to remove the 3 wires from the NA plug and fit them in the 3 'large' holes on the TT one. Job done and took all of 3 minutes :)
