Hey everyone, I have a 96 SC400 and wanted to go TT. Now i wanted to know between the two models (300 & 400) are the wiring connectors the same for the ECU plug in? If i wanted to go TT 2JZ, do I need to get the 300 engine harness and have it extented into the JDM 2J? Or can I just used my harness? Are there any differences? Please let me know...Thanks

The harnesses are not the same, you would be better off with the 2jz harness for less headaches. Hope this helps.
