Changing 73 Column Ignition switch to 67-72 Dash Ignition Switch - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Hi All,

I'm in the process of installing a shorter, collapsable tilt steering column in my 73 Squarebody. I couldn't get one with a column key locally that complied with our laws, so I need to put an ignition switch in somewhere.

I was thinking about using a dash ignition from a 67-72 c10, hoping the wiring would be similar.

Looking at the wiring, I'm honestly a bit confused. Is anyone able to help me out?

It's each of the stages and what to swap to where that has me. I feel like the squarebody has a lot of swap wiring that the early one doesn't and it's throwing me off! But also I don't have a great wiring diagram to work off of for the earlier model either.

I appreciate any help y can offer. Thanks!

Actually I have found a local ignition switch off of a Holden - Basically Chevy (GM) in Australia.

I'm hoping I could use that? I can't find any details searching sorry!
