If the 16V had a 5 speed behind it, it might have 5th gear switch wiring, it might not (some trackick trannys had a 5th gear switch, some didn't). If it does, hook the samurai tranny 5th gear switch wiring up to it. If it doesn't, don't worry about hooking it up. All the 5th gear switch does is cut the EGR operation, when the tranny is shifted into 5th...supposedly to help get a little better MPG.
