    Different knock sensor wiring

    I am in the process of slowly changing my ls1 intake for a fast 92/92 after removing the intake i find my wiring for my knock sensors are different then anything i have seen.

    is that normal?

    Another quick question in that on the back of the stock intake there is 2 lines, one to the brake booster and the other small line that runs to a sensor. My fast 92 does not have the nipple in the back for the 2nd small line. Where does it go?

    It's not obvious to me what you think is odd about the wiring?

    The small line I believe goes to the heater controls if I remember correctly.

    yup the small one goes to the heater controls, you can add a vaccum (T) in the large booster line to run the heater controls.
    knock sensor wiring is normal

    One more quick clarification
    For the lines on the left i have the top one leading to the back of the intake manifold and the bottom i have capped off. Then i need to cap off the 1 end of the T at the back of the manifold?

    the short one on the back pointing to the passenger side hooks to a hose coming out of the fire wall that works the heater controls.
    plug the other one.
