Your 1993 is an OBD1 so you should have success, but it is much trial and error. Go to HHO-INFO.com Get 316 stainless plates. There's a guy on ebay who sells them pre-set up for $49. Be sure to use 8-gauge wire ! I hope you can find the room for a decent size unit. This is the FIRST thing you must do! Good luck
