Can you get the harness from the 06 TBSS? This is what I would run.....and the ECM. The question will be if the bulkhead in the 06 TBSS harness will bolt up to your underhood fuse box. Im betting it will. You will have to have the ECM flashed with your VIN so the TCM and BCM all play nice together. I would call John spears and talk to him before you spend another dime though.
