@michael336: Nice!

Why not try getting needle nose pliers and pull the pins out gently and re-pin the plug, or even splice the wires right before the plug, and keep trying different combinations, until it works? There's only a few wires, so I am sure you can find the correct pin-out easily.

Or, try to find the original car the TB came from, look at the harnesses' plug, and take note at the wire colors...then, compare it to the frs'/brz's harnesses' plug and switch any wires around that doesn't match the two cars. (ie: black, black with white stripe, yellow, yellow with white stripe, or any other colors...a lot of times, colors correspond to the same thing in the same manufacturer or in electrical, in the engine harnesses).

I've done wire harness repairs and mods a couple times before in the 90s, and I remember it was relatively easy to find which wires did exactly what from only it's color (and just a confirmation with a multimeter to make sure it was true). Maybe the twin has a manufacturer's color code for electrical/engine harness work, repair manual maybe?

Another possibility...if the TB's sensor's plug and pin out is actually the exactly same b/n the twin and the car the TB came from, then the ECU's actual plug harness could be the one that is pinned a little different..obviously a little harder since there's hundreds of pins..but actually easy to re-pin - use micro needle nose pliers, gently push the male/female pin out of the ecu plug, then re-pin. (do at your own risk, and after a lot of research and multimeter use to make sure though, lol)
