Re: conversion harness (BrianFreels)

im guessing theres not enough demand for an auto conversion harness for them to produce it. face it not many people fix up auto civics

the harnesses arent transmission specific. you can use an auto ecu and an engine with an auto tranny with any conversion harness

It really doesn't matter. OBD1 ECUs wont be able to control the OBD2 automatic tranny anyway, theres at least one extra solenoid on the transmission. If you had a conversion harness and an OBD1 D-series tranny you might be able to rig something up. If its an integra or you're trying to do a B-series swap in a civic you're kinda screwed.
