Hey guys. I'm about to install the apexi turbo timer Pen into my st204(5sfte). I've been researching but can't find the right answer that Im looking for.our celica could use the hks tt-4 harness for supra, but I believe its only for the 3sgte, am I correct? Or, will that work for the 5s ecu as well?

Thanks!
