xj guage swap

i've swapped out my idiot light guage cluster for a set with tach and full guages.1988 xj 4.0.everything works except for the coolant temp guage and the oil pressure guage.i hooked the jeep up to a scanner and temp read 195 but the guage is pegged,do i just need the sender for a guage style engine,and oil sender for the same.

ya u need to replace ur senders with one for gauges, and not lights.

Be carefull removing the old temp sender. It can snap on you real easy.
