jono Posted September 19, 2015 Share Posted September 19, 2015 (edited) starting to suspect you have Disco's old spidey with the three wire TPS from series 1 EA82 non spidey inlet manifold. He welded a plate onto his spider to be able to use the TPS that went with the vehicle and its ECU. Yep, proper spider throttle opened opposite to non spider. Throttle plate/butterfly same diameter.. Series 1 TPS were three wire, one being earth ? the other for idle position, the other activate at about 60% open. The S in TPS for theses means switch, not sensor. Next gen EA82 had potentiometer style sensor feed for the ECU, some were four pin, some others four pin and an additional three pin plug with three wires off the side !
