That's an interesting question. My 1600 Duetto also lacks that switch. I assume this car was first sold here in California, since it had black plates when I got hold of it in '83 (though yes, it could have come here prior to '69 and still gotten black plates. Were they issuing plates beginning with a "W" in 1967?I'm thinking that the hazard system was a dealer add on that was required in some states and not others. My 67 doesn't have one.
OK, now that sprintgtc has been kind enough to show the schematic in the following post, it looks like you need a DPDT switch. Any Lucas bat handle switch will work electrically and look correct. Two minutes of internet searching got me to this source: http://www.holden.co.uk/displayproduct.asp?sg=1&pgCode=020&sgName=Electrical&pgName=Switches&agCode=0502&agName=Toggle+Switches&pCode=020.251 I'll bet a little more searching would yeild a domestic source (perhaps Moss motors?).Resto120 said:....but does not have the switch. Does anyone know where I can find one? I've found the 2-wire switches that look similar.
Crawling under my dash, I do see the two holes in the bottom of my heater control panel. Hmm - now you have shaken my faith.Here's where it mounts on the heater control. This is my spare. I have 3 of these, and they all have the hazard switch. Do the Duetto's without the switch have the mounting holes?
I have the switch, and bracket right on my desk. It mounts under the heater control. PM me if you need it. Is this board great or what!
