    How to rewire the ISC for 60mm TB

    1g/94GS ISC

    1g ISC plug colors may differ, but the pinout is the same.



    94-98 7g SOHC/ 95-99 Eclipse Spyder

    Spyder ISC plug colors may differ, but the pinout is the same.



    1g/94GS pins.......-.......7gSOHC/Spyder pins
    .......1..................................5....... ...
    .......2..................................1....... ...
    .......3..................................6....... ...
    .......4..................................2....... ...
    .......5..................................1....... ...
    .......6..................................4....... ...

    There's a pin left on the 7gSOHC/Spyder plug. That's the ground pin-3. 1g Style ISC does not use ground - it uses two +12V and that's why pin 1 on 7g/Spyder plug needs to be spliced into two for pins 2 and 5 of 1g/94GS plug.

    I though 6g74 has a 65mm TB

    But do port it. It makes all the difference in the world

    For people doing the DOHC swap or going turbo and not wanting to port the mani this also works for a 2G TB and IAC as they use the same IAC.

    I grabbed a turbo TB from a 1991 talon TSi the wires are 1-6 in the order of your illustration
    1-blue
    2-red
    3-yellow
    4-black
    5-red
    6-white
    Iirc black is always ground but it does have the two red wires you mentioned bit no green and instead of a white at 4 its at 6 and the black is at 4

    Any input
