Something is not right here. There shouldn't be an ISC, it should be an IAC on a 1990, and there shouldn't be " a wire," there should be a two-wire hardshell connector that just plugs into the IAC valve. Did you have a connector come apart or something? The circuit is simple. It has a two wire connector that plugs into the IAC, and the two circuits run all the way back to the big 60 pin connector at the PCM.
