Hi All, I have a 91-94 ECU on a 89 Colt turbo harness with 91-94 type of TB with a new ISC from DSMISC that test OK! My ECU driver IC107 blow again. My wiring is connect like this (diagram from 91-94 manual shop) : 58 Blue(L) wire to pin 1 ISC 59 Yellow wire to pin 3 ISC 67 White wire to pin 6 ISC 68 Black wire to pin 4 ISC But if I check the diagram from a manual shop of 89 Colt turbo the wiring is as follow: 58 Blue(L) wire to pin 1 ISC 59 Yellow wire to pin 3 ISC 67 White wire to pin 4 ISC (Instead of 6) 68 Black wire to pin 6 ISC (Instead of 4) So which of these manual tell the truth? How should I wire my harness? Could someone tell me the color of the wire at the ecu harness for pin 58-59, 67-68? And the color of wire at the ISC 1-3, 4-6? With the model/year of is harness? |

More than likley your ISC motor on your throttlebody is blowing the ECU driver... Change the ISC motor on the throttlebody |

yea apparently it's like an infectious disease. The ISC will kill the ecu, and a ecu will kill an ISC; making it hard to tech issues. |

Your electronics on the 89 turbo colt are the same as a 1990 dsm, and the pins may have changed with 91+ models. The manual for the 89' should be correct. |

Ditch the isc with a full fiav blockoff plate and adjust idle with the bypass screw. I've never had a problem after doing the plate and no more coolant lines or idle issues due to the isc. |

At what rpm did you set your idle?

For the warm season, I turn it down as far as it'll go before it stumbles, then add 100 rpm to it. Ends up around 7-800rpm for idle. When it gets cold out (winter), I crank it up to around 900-1000. |
