78 280z 2+2 bcdd wiring

Featured Replies

Could someone tell me where the wire from the bcdd is supposed to go to? Where is that wire located and what color would it be? The previous owner had it running to one of the black wires for the temperature switch(?)(facing the front of the engine the switch to the right of the temp sensor. Has two black wires connected to it.).He also had that black wire disconnected from that switch. Any help would be appreciated.

The wire from the BCCD plugs into the white/black stripe wire in the harness in front of the left shock tower below the coil. Sounds like you need to get an FSM because facing the front of the engine, there is nothing to the right of the temperature sensor since it is the one on the right. Left to right, thermotime switch, thermal transmitter (single wire), temperature sensor.

Thanks for the info. Your right, I do need to find myself a factory service manual. I would be well worth the money.

Could you tell me where the white wire with black stripe goes from that connection? The previous owner also had the same color wire ,(directly below the fuel filter in main harness) , cut and ran a jumper wire over in front of the radiator, and grounded it to the distributor adjustment bolt. Does the ecu control the power going into the bcdd, and if not what controls it? Thanks for your help.

The other end of the w/b wire goes to the relay on the back of the speedometer.
