    Excess lamps in dash on '71 Mach 1

    Hi,

    after completely reassembling my dash, I have two lamp sockets for which I have no idea where they go.

    I have checked all switches and each of them has got a bulb/socket already. From the reach of the cable, they don't not belong into the console, and the console already has it's bulbs.

    Does anyone have an idea where they should go? Is it possible that they belong to an optional piece of equipment I don't have? I'm not sure whether the bulbs were in the sockets when I disassembled the dash.

    Thank you, Manfred

        Hi Nance,

        unfortunately, not. My clock is in the center console and the reach of the cable would be to short. The clock already has it's own small wiring harness providing two bulbs and plugs into the main harness. And it is in place in my car.

        Thanks for the guess, Manfred

          Manfred -

          Do or did you have an 8-track? I came across something in another forum that said "The blue wire with red stripe is the dial light (to the 8-track).

          Just a suggestion,

          Doc

            check your switches under the steering wheel it looks like the bulbs for the cig lighter and the windshield wiper switch

            it cannot be a center console light that is on a separate harness.

            and it cannot be for the center gauges because those are also on a separate harness

              According to the repair manual wiring schematics, light blue with red stripe is console clock lighting. The harness should also have a plug for clock power (peel back the electrical tape and see if it's been cut from yours). It's just long enough to reach the clock.

              The 72 schematic also shows a double light harness to the center gauge pack (temp,alt,oil). This was also light blue with red stripe.

              Good Luck... Rick.

                Hi,

                I just re-checked that all bulbs are there. The center console was a good idea, unfortunately it is there inluding the clock power connector.

                I have ckecked the following bulbs:

                Wiper switch
                Headlight switch
                Cigaret Lighter
                Heating switch panel in center console
                the three instruments in the center console (oil, temp, ...)
                Clock in center console
                courtesy lights

                As far as I know, the main instrument panel (tach & speedo) has only bulbs that are plugged into the circuit board (no additional bulbs with wires). Right?

                To my knowledge that is all there is, but I still have the two excess bulbs. I will probably stow them away until I find out one day what they are for.

                Thank you & regards, Manfred
