I recently purchased a used supercharger off of craigslist for my 3.4 Tacoma. The supercharger came with the TRD 7th injector kit including the TRD piggyback ECU and Junction Box. In the TRD 7th injector wiring instructions and photos there appears to be a red wire coming out of the back of the 31pin connectors that plugs into the TRD 7th injector ECU. In the manual it is labeled as the "Ignition Power Wire" and gets soldered in to the ignition on wire of the factory ECU. This red wire is different than the "pink" wire that comes from the actual 7th injector and goes into the back of the same connector I think? So the red "Ignition Power Wire" seems to be missing from my harness and I am hoping someone out there that is running this setup, or has the TRD wiring connectors laying around can look at the pin spot that the red wire comes out of and let me know where I should insert a new red wire. Where I have drawn the white arrow with the question mark is the A2 pin that I think actually is used by the "pink" wire, but I saw the remnants of a wire connector in that spot so I wasn't sure.
