HKS has a premade TT harness.
Part Number:
TT-04 desigend to work with the ST205 and JZA80 (Mark4 Supra)
Clicks right into our harness.

Just get the HKS Turbo Timer with it. Its great!
Here it is installed

so, your saying the same harness that works with an mk4 supra should work with a 6th gen? this is kind of what i was thinking, since most of this stuff is universal as long as you stick to the same year toyota.
i went with the Blitz DTT DC4. it has a built in digital boost gauge, with peak hold and over boost warning!!! this is the main reason why i bought it. i dont even plan on using the turbo timer feature (who knows i might hook it up) hahaha. i read some reviews on mr2oc about it, and the boost gauge function seems to work very well.
