I am restoring a 70 SS 396 with factory cowl induction hood and turbo 400. I have several wiring diagrams for chevelles but all show the transmission TCS but none show how the cowl ind solenoid wires together with it. The engine harness was partially cut when I got the car and I am trying to fix it. Is there a seperate relay for the hood solenoid and the transmission TCS? Does anybody have a source for a diagram which shows this?
