    HZ hazard switch

    HI
    Did HZ have hazard switch on the steering column , I'am thinking not but my son has a 10- 78 HZ 1 toner with hazard switch on the column and what appears to be a WB brake master cylinder. The car has matching numbers on body & chassis and doesn't appear to have been in a bad crash. I just find it strange that someone would change out a steering column.

    78 would not have had factory hazard lights/switch. I think Hazards came in around late 79, or 80. Probably the column is out of a WB.
    Check where the windscreen washer squirters are, you may have a WB cab. Also, if it's a got a WB m/c it would be a WB booster, which is different from HZ

    The October 1980 Holden HZ Parts Manual (last parts manual for HZ) has no listing for the Hazard switch.

    That clears it up, must be a WB column, (or part of one)

    It is something I would have 100% done back in the day. Always upgrading where you could at little expense.

    Yes Max just checked and it has WB washer jets, so I would say your right it's a WB cab.

    I don't know if they work, it has no battery or motor, I stole the 253 out of it to use in my panel van.

    It could be an HZ chassis with a WB cab fitted. If all the plates were transferred, then all of the numbers would still match !

    There are many small differences between WB & HZ, much of it to do with wiring.

    Does the plug at the base of the column match the blinker switch wiring ?

    Where the ignition coil wiring is at the firewall, is the coil wire a skinny yellow one or a thick pink one ?

    Dr Terry.

    Hi Dr Terry Yes the blinker plug matches the base plug and it's a small one not a wide one like on the early models so I am sure now it's a WB cab, but that's OK it;s just interesting what you find when you look at the small detail. I tried to post a picture but it wouldn't upload.
    Cheers
