THAR-ONE-SUB2 & EVO ONE on 2020 Subaru WRX PTS

Sun, 14 Mar 2021 00:31:28 +0000

I have installed the THAR-ONE-SUB2 in my US WRX per the instruction guide, page page 7/11 T-Harness - Automatic & Manual Transmission

ASK:
1.) Why is the car not starting with the Yellow/Red and Yellow/Green separeted per the installation guide
2.) Does my US WRX have to follow the Canadian Vehicle steps, if yes why and if no what is the difference

Installation was simple as mainly 2 connectors and areplug N play. I master reset my Evo One, flashed the 2020 WRX firmware and follow the programming steps on page 8/11. When I get to step 5 to start the car, the car starts and shuts off immidiately, eventually not even turning the starter. The lights on the Evo One stay solid for Red and Blue and programming does not complete to follow up on the Dcryptor part. After a little troubleshooting I found that I can get the car to start if I reconnect the Yellow/Red and Yellow/Green wires I cut eariler making the car at least drivable again.

It appears this particular T-harness isn't as plug and play as it is compared to T-harnesses for other makes and models. Does anyone have a guide to locate the plugs for this car? The guide only helps so much because it's not made for use with the T-harness and none of the plugs it points to fit the harness except 1A.

Any inputs or available guides for this particular T-harness would be helpful.
