i'm making my know and wanted to know where to connect it to the tranny? is any point on there good? also, i heard theres one that goes near the ECU, wheres that? shoots

 

here's a pic of the ECU & TCU connections for my '05. Infiniti has reconfigured the placement of these modules throughout the years, so yours may not be located in the exact same place... pic from futher back found here

I do not have a pic of the tranny connection, but a pic can be found here (post #140) that shows the same wire coming from the engine bay.
