I noticed there is 1 too many sensors here (modified mr2 i got and im fixing it up, yes i understand the possible headaches, but ive fixed most problems). Looks like the oil pressure sender is unplugged (anyone know the wire colours so i can search through the loom?) but seems like theres an extra water temp sender maybe? One on the far right is for the gauge (checked and it works perfectly) the one in the middle is for the ecu, so the far left (the white one below the green one) is for......?
