I suggest purchasing a repair manual for that vehicle. Bentley published the best manuals for Volkswagens, if you can find one.
correct it will fit. be sure to take lots of pictures before you pull all of the wires off. so you have a diagram of where they go after.

To remove the speedometer from a 1974 Super Beetle, first, disconnect the negative battery cable for safety. Then, remove the dashboard cover and the screws securing the speedometer itself. Carefully disconnect the speedometer cable from the back of the speedometer, and then pull the speedometer out of the dashboard. Be sure to handle it gently to avoid damaging any components.
How I have to do for replace a little bulb on the ODO speedometer cable on 1973 Super Beetle ?
I would suggest you purchase yourself a Chiltons or other repair manual. I wouldn't advise trusting your wiring needs to the internet. There are many many reasons why internet wiring diagrams can be troublesome, most of the time it has to do with the fact that no one reviews these diagrams before they go up. For the sake of you and your beetle, i would suggest a manual. However, should you want to view or download one there is an official VW wire diagram for it here, however contents in the index are written in German. http://www.1302super.com/page19a.html
Rewiring a 1974 Super Beetle involves several steps. First, disconnect the battery to ensure safety. Then, remove the old wiring harness, taking note of the connections and routing. Install the new wiring harness by following a wiring diagram specific to the Super Beetle, connecting each wire to the appropriate terminals, and ensuring all grounds are secure. Finally, double-check connections and test the electrical systems before finalizing the installation.
