My dad bought this logic module in the early 90's for his 87 t1 Shadow ES and didnt like how the cuise control didnt work with it on, so he took it off. He sold the car in 95 and all the TM's he and I owned are all SBEC cars. Never had a chance to use it again, so it has sat ever since. Comes in the original box and has the instruction sheet. $75.00 o.b.o.
