Fan switch sensor is the only thing that comes to mind. Obd1 Ls have in the Thermostat housing, Obd0 Ls have it on the back of the block. Replace your thermostat from the obd1 ls to the obd0 ls and you wouldnt have to rewire anything. Also obd0 ls's have a extra sensor that obd1 ls's do not use Oil temp. Its the green connector on the back of the block besdie the big two pin connector ( which is the fan switch on the obd0 ls)
