400w inverter mod Manual Transmission

Despite a lot of tutorials on converting AT Tacos to run the inverter at 400W while driving. There's none on MT, the little info I found was incorrect.
Below the cupholders by the driver is a plug. The blue wire with black stripe is a clutch sensor, it sends 12v until the clutch is depressed which triggers the inverter to drop to 100 amps.
I cut and jumpered the inverter side to the cigarette lighter 12V.
I also cut the purple/white as the internet threads said this was a vehicle speed sensor to the inverter...I need to test that voltage while driving to confirm. Regardless it works...the solid purple wire you're supposed to ground according to AT tutorials doesn't go anywhere past the connector...a remnant off the inverter from AT installs.
Access to the back of the 12V cigarette lighter requires removing a lot of the dash but just remove the 12V plug from it's black plastic (still a pain) and hardwire a 12V access under the cupholders.
I'll post pics if anyone is interested.

 

Wait what
I thought you just do the 400w anytime harness mod. Regardless of trans. Which might be made by FBC. I forget. No?

 

You can buy a wiring harness for $$ but I'll confirm it's doable to diy. This was on a 2015 manual transmission.
