Turbo boost control solenoid with the push to connects mounted in a hold down bracket. Way bettwr than just zip tued to the brake lines like before lol Left port goes to the wastegate bottom port, top port goes to the manifold reference, and the right port to atmosphere. Pretty basic wastegate controller. For now its set for 10psi and 14psi for 2nd map. Was using this setup for the old ls1. Gonna leave it at this range until its tuned to 14 psi, then ill adjust the 2nd map for 22psi later.
