OK ...I think I am wrong on the yellow as a turbo protection relay. Based on the shop write up it cuts the fuel pumps and then cuts the CDI box.... as it says for an orderly reduction in combustion... I guess this is part of a shut down procedure to clear the cylinders of gas due to the continuous fuel delivery process...The over boost relay is the round relay- red/blk and that cuts the power to the fuel pumps when the over-boost sensor causes the relay to trip....

John Walker if you are out there ....please help us clarify..
