    There is a small white wire dangling near your distributor with a female spade terminal...you'll see it. Attach the wire to that. /forums/images/graemlins/waytogo.gif

    /forums/images/graemlins/thinking.gif I'm pretty sure that's where that white wire is coming from...all I know is that there's a white wire there that you hook into. /forums/images/graemlins/dunno.gif /forums/images/graemlins/waytogo.gif
