'88 Eagles could be optioned out like Eagles from any other year. The '88's had a few more standard features not found earlier but not the heavily optioned cars like the myth makers try to tell us. You need a whole lot more than the handle. There is a control module that goes under the dash, and the actual mechanisms under the hood and whole lot of wiring and vacuum lines plus a dedicated vacuum reservoir to make your late 70's technology work. You are better off getting a modern, much more reliable setup for a non computerized, carbureted car than trying to use the OE stuff. You will thank yourself in the future.
