  • Series III dash wiring help needed

    I've been tasked with installing a new loom in a 75 Series III. This thing had its dashboard completely disassembled for paint work.

    The bits for the dash are a bit of a mess. I'm not wanting to sort and refurbish or seek replacements. That's someone else's job.

    My question is can I put the steering column back together without putting any bits in the way of whoever has to mess with the dash?

    Thanks

    It’s some years since I removed the steering column assembly from my Series 3 - but I recall having to remove all of the dash other than the instrument binnacle in order to do it.

    That is one of the classic PITA jobs on that Series. Even for relatively minor issues like refurbishing the steering box - the original reason that I removed mine.

    Presumably you can reinstall the column without interfering with subsequent dash reassembly because that’s the usual sequence.

    Cheers,

    Neil

        Which loom? Think Neil is right on the main loom, my dash has been apart, really apart for an owner or two, but the gauges/aux panel/stuff inside the binnacle and column are attached and all the wiring is present. Don’t envy the person who is going to reassemble. In my case, that’s me but a paying customer, ouch depending on pocket depth? Can post a picture if needed but on a s3 picture all the fancy dash pad and duct work stuff gone revealing how the instruments/switches are connected, how the loom is run, and the column plus An indicator stalk.
        Looked at the diagram and found the chassis loom missing but the engine and main loom present. Also randomly discovered elsewhere there are separate part numbers for the pigtails going to the headlights, not sure if those are included in the main loom or not. Mine seem to be cut near the bullet connectors.

          Hello again.

          This is what the dash area of my truck looks like at the moment.

          I have a full Autosparks loom to fit in due course.

          Cheers,

            Never cut the green wire. If you do it will blow up.

            Or is it the red wire?

            Common sense is no longer common.

            Put your phone down and drive. Stop driving distracted.

              Yes, you can install the column and associated bits before the SIII dash parts are set in place. The steering wheel is best removed before the binnacle support and other part are installed but the column needs to be there.

                Neil, looks like we are at about the same stage.

                  Yes, looks like it.

                  I’ve had the Autosparks loom in its unopened shipping box for several years waiting to build up the courage to open it and work out how to install it.

                  The day will come.

                  I heard somewhere that the looms come without instructions but should be the correct colour markings. Suggestion is to lay the components - three in my case - on a clean floor and use the wiring diagram to identify exactly what each bit is doing before attacking the job on the truck. Helps if the existing loom is still in place.

                  Cheers,

                  Neil

                    take it slow and painful. 1) which loom contains what circuits isn’t listed but chassis and engine loom connect to the main via plugs. 2) depending on what year your truck left the factory, the diagram may or may not be updated. Ie how the aux panel is configured for various lights and the failure warning stuff on the brake system (and booster), towing.

                      Thanks. The way that you set up the guides etc was useful - I'll likely do much the same.

                      The loom(s) that I ordered from Autosparks for my Series 3 included the main, engine and chassis (rear) plus the towing plug loom. It was specified for the dual circuit brake model with the failure warning lights etc. Also two speed wipers which my present loom doesn’t have.

                      Once I remove the bulkhead for painting and get the panels back I'll have to seriously start to consider the installation tasks. I completely rewired my boat some years back without access to a wiring diagram and got it working fairly well - just had to approach it with a positive attitude and a ready store of patience.

                      Cheers,

                      Neil
