Electrical - Switch Variations

[DoubleNickels]

Everyone:

My turn signal switch is giving up the ghost (1974 FJ55). Looking online, it appears replacements are still available from Toyota, but I don't understand why there are a couple versions offered. Here's an example, and a screenshot below:

Note the same applies to the wiper, hazard, etc. - multiple versions listed. Can anyone help clarify the difference and/or which I should select? Wondering if the differences are major (e.g. wrong connectors!) or minor (e.g. font on the knob).

Thanks.

Calvin

Thanks Jim. I do indeed have the dimmer option built into that switch itself (flick forward for bright). How did/do you decipher the part numbers and that functionality? Any way to make sense of the other switch versions as well? Really appreciate the intel.

Maybe this information will help explain the differences:

84310	SWITCH ASSY, TURN SIGNAL
84310-21010	(09/1972 - 08/1977)
84310-60070	(09/1977 - 06/1980)

For what its worth, I was able to take my switch apart clean the contacts, replace the tiny ball bearings inside, and put new dielectric grease inside. It now operates like new. Mine is from a ‘69 so it may be different than yours.

the plugs changed, when the key moved from the dash to the column .bullet connecters to a square style

Ah! Is that essentially it? Still confused by the multiple offerings on ALL the switches (e.g. the Hazard). There must be a cheat sheet, somewhere, that describes the differences.

I used a newer column , and just made a jumper wire to go from the old 3 flat pin connecter to the new square one ,
