Time
Control Unit:
The picture shows two Bluebird Time Control Units along with an
illumination control switch previously mentioned. The units can be found in the
right hand kick-panel in the driver's foot-well. They are quite complicated, but
if you can understand the schematic diagram and are good with a soldering iron
then this is worth doing.
It provides interior light fade, replaces the annoying lights
left on buzzer for a pleasant ding dong,
adds a timer to the heated rear window,
replaces the ugly big illumination control knob for a neater switch and provides
a flashing seatbelt warning lamp to all the three Silvia cars. There are other
features that I have not used.
In addition to the standard single interior light all three cars have added lights.
Above each foot-well is illuminated (foot lights), and the red light in each door illuminates
(step lights).
The interior light switch has been modified so that the switch off position
controls all the lights on the system. The interior light fade is wired to
operate from the driver's door only.
Bulb
Failure Sensor:
Found again in the Bluebird, in the boot behind the trim on the driver's side,
near the top of the opening. This unit monitors stop/tail lamp bulbs, but you
can use it to monitor reversing lamps, rear fog lamps and front
clearance lamps
(provided they are 5W) The rear lighting on all three cars is identical, as silviagod's wife's and the spare Silvia had to have their rear lights changed
for the earlier type.
I couldn't tolerate the style of the later
units, especially with the chrome strip. This was not a straight forward job as
usual as there was no reversing lamp or fog lamp in the earlier type.
The problem was solved using a black relay instead of the blue one and the inner
brake lamps became fog lamps when needed. The bumper had to be cut to house two
reversing lamps. There are also yellow sensors that I have found in the Nissan
Sunny. These monitor 2 x 21W + 2 x 5W whilst the green one monitors 2 x 21W + 4
x 5W.
One-Touch
Amp:
This is the unit used to provide closure of the sunroof fitted to silviagod's
sunroof. It is also used to close the sunroof and windows on the 200SX project.
It is triggered from a momentary earth and can be easily linked to a central
locking interface.
The wiring colour codes for the switch operation are
as follows:

Headlamp
Failure Sensor:
Due to lack of availability these units are only fitted to silviagod's car. They
can be found in the rear of the 1984 Bluebird Estate models as they monitor
stop/tail lamps.
The ground wire from the bulb runs through a coil of wire in this unit creating
a magnet, a reed switch in the centre of the coil is switched telling the
circuit not to illuminate the warning lamp. If a bulb has blown no current
passes and the light illuminates. The units were originally designed for 2 x 21
W and 2 x 5 W monitoring so two units were used to make one. Two of the heavier
gauge coils were fitted into one unit and the headlamp earth wires sent through
each coil.
I have since tried 100W bulbs and the unit copes perfectly.
Silviagod's car has the front fog lights monitored by one of these modified
units.
Passing
Timer:
Automates the flashing of the headlamps with a brief touch of the control
leaving the hand free to gesture at the person you are flashing. Fitted to the
three Silvia models and planned for the 200SX project. Listed in the manual but
with the irritating except Europe phrase.
Extra space:
I have thrown up another little site with the intentions of improving it and
adding more pictures. My web skills are only limited but I am trying to learn
with the limited time I have available. Please have a look and feel free to
offer suggestions.
