the clock is powered by fuse #3, 20amp. this fuse also feeds the brake lamps and most of the interior lamps. the lamp for the clock, however, is fed by fuse #7, 5amp, which is wired in series with the headlamp switch. if fuse #2 is blown, which feeds the headlamp switch, fuse #7 will not receive power.

from fuse #3, power travels along a red 16 gauge wire to a soldered junction somewhere in the harness. two other wires branch off from this point, to feed the stop lamp switch and dome lamp. your clock feed wire now becomes a red 20 gauge wire and continues through the main harness to a twin terminal connector. at this point there is an optional subharness that feeds the clock and clock lamp. the clock feed wire passes through it and goes to the clock connector. the connector resembles a "T". the clock feed wire will be the vertical terminal, and there will be two black wires coming from the horizontal terminal. one will go to the clock lamp twin-terminal connector, providing its ground, the other will go to the "title lamp plate" which is the plate on the back of the instrument cluster that provides a common grounding point for all lamps.

now, from fuse #7, you have an orange 20 gauge wire. this wire travels to another soldered junction in the harness, which feeds several lamps in the dash and terminal K on the left circuit board. from there the orange wire, still 20 gauge, goes to the other terminal on the clock subharness connector. from there it goes through the clock lamp connector to power the clock lamp.

with your multimeter, check the horizontal T terminal for the clock power supply, it will have battery voltage to it at all times. if it doesnt, check fuse #3, the subharness connector, and any points inbetween that may have been hacked to install stereos or alarm systems or whatever. it is very unlikely the soldered junction will be at fault, but i have seen it happen. the vertical T terminal will have continuity to ground at all times. if it doesnt, check the spade spotwelded to the title lamp plate, if the title lamp plate isnt grounded no other lights on that plate will work.

now pull apart the clock lamp connector. the orange wire will get power only when the headlamp switch is on LAMP or PARK. if it doesnt, check for power at the fuse on both sides and if there is none, go back to the headlamp switch. if the fuse is okay and is getting power to it, check the subharness connector and any points inbetween. i would suspect any visible wiring under your dash that has solderless connectors or unraveling electrical tape, post a picture and we will tell you what should and shouldnt be there.

Hi, i don´t speak french.

My question about wires is Where I connect every wire?

you connect a wire to the clock that gets power all the time, and another wire to the negative side or frame of the car. the clock has only two wires. one to +12V, one to - or ground/earth.

S....boom,

Nice job explaining. I was able to follow along, and I don't even have an Aspen.

Aspen79,

Wire decoder ring department:

Orange wire feeds dash lighting, and is switched by activating the head & parking lights.

Red is generally hot all the time. This powers the clock

Black wire is often the ground, or a wire that goes from a device like a light, or clock and attaches to the metal under the dash.

Yellow runs the dome lights etc.

Wire gage:

Higher the number the smaller the wire, lower the number the fatter the wire.
20 gage is the smallest you will find in your car.

Yellow and blue wires have me drawing a blank, this must be a clock that was not used in north american models. why would a clock need five wires to tell time? is it digital? it must be if it needs the blue wire as an ignition signal.
a digital clock in '79?

thanks, so Where I connect the orange wire and the yellow wire?

orange wire needs power when you turn on the headlight switch.
the only yellow wires i know of anywhere near your clock are for the dome lamp circuit. why your clock would need to be wired into that i have no idea. the clock is supposed to be lit up with the rest of your gauges, not the dome lamp.

so your clock has five wires coming out of it with a single plug at the end of them? or are they just five wires hanging loose?

can you post a picture?
