Message So buy the 90-93 tt 5-speed harness from member YugoBernie. He's one of the cheapest, and he'll make sure you get what you need. You can use the NA fuel pump and controller as well without major issues as long as you're using stock injectors I believe.

I remember your post about the harness being FUBARed, which really sucks because even guys intimately familiar with these cars loathe installing the harness while the motor is in. Maybe you should consider lifting it back out just to get the harness in? Since you don't have the piping hooked up yet anyway, it might save you some time, and will certainly save you a lot of pain, frustration, and words.

You can use the tt ecu, but if you wanted an upgraded ECU so you can increase boost, just mod the NA ecu (as long as the years match). This way, you'll have a stock tt ecu and an upgraded ecu, so you can use one in case you come across problems in the future. Otherwise, you can sell the stock tt ecu, which are more valuable than the NA ones anyway.

Good luck!

Cheers,
JBrobst
