Homer Posted August 15, 2008 Share Posted August 15, 2008 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?

miko_supra Posted August 16, 2008 Share Posted August 16, 2008 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 http://www.supraforums.com.au/forum/showthread.php?t=25065 hope this helps Quote Link to comment Share on other sites More sharing options...
Homer Posted August 16, 2008 Author Share Posted August 16, 2008 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 Quote Link to comment Share on other sites More sharing options...
