I don't know why they would need the TAC harness to mod the main harness.

If you have both ends you can solder in extensions. To be honest, you'll have to take the connector on one end apart to get it through the firewall. I ran mine along with the DLC wiring through the old clutch grommet but had to pull them all out of their connectors to do so.
