you do have to bypass the starter interrupt too, that's true, unless it's already been done, which maybe it has been if it's clicking.

the cable from your 1995 will work fine. you can google pictures of either connector to figure the pins out.

the 'older' connector uses top right as ground, and bottom right as data. the 'newer' cable uses bottom left as data, and the 5th pin in the top row as ground.
