  • Is a BP temp sender different than Festiva?

    Last night I studied wiring diagrams for a Festiva and found that the temp gauge wire is a yellow/white wire. So today I found the yellow/white wire in my engine bay and hooked it up to the sending unit thing in the thermostat housing on the BP. The gauge still doesn't read. Is it a different type like a NTC negative temp coefficient and the Festiva is maybe the opposite?

    Did you use the Festiva temp sender?

    I'm pretty sure you have to use the B3 temp sender. It should screw right into the BP.

      I don't think it has the B3 temp sender, it came with the BP. Thanks for the heads up.

        They're different, you need the festy gauge sender. It's just that a festy gauge uses a different range sender unit than the donor car the bp came from...ask me how I know.

        The computer's temp sender is in the head, between the thermostat housing and firewall.
        The gauge's temp sender is on the front of the head, in front of the thermostat housing.
        The unit IN the thermostat housing is the radiator fan switch and you may need the festy version of this as well.
        This needs to be of the "normally closed" variety, when the engine is cold (below about 200 degrees F)

          Oh no wonder it isn't working, I have it hooked up to the fan sender. Thanks for the info, very nice!
