Is a unichip PNP harness for a 2007 scion tc going to work with an 06 tc stupid question I know my guess is no but I've got to ask since all other parts for the most part work across the board as long as its a 1st gen

 

Don't know much about the Unichip, but the 05-06 ECU has 5 connectors and the 07-10 ECU has 4, so I would assume the answer is no.
