Since you are running a 12 volt system this one in the lowest of the left page probably would work:

Not at all sure why it would need a separate ground wire though...

Found another relay to try. A good used German Hella 91MS2J2 x 18W-6V relay, with +15, S54, and K marked terminals. It flashes the speedo indicator with ignition switch turned on, and does not with key switched off. Exterior turn and E-flashers work with ignition switch turned off or on. Nice healthy click/clunk to it so easy to hear as long as not parking right next to a Jack hammer being operated. Can be screw adjusted for faster or slower flasher cycling.
Nice to have that all work as it should after 30 years!

Here are images of the relay. Had to do two and turn it to show off the OG print on the side.

Sorry to drag up this thread, but have been having similar issues with my flasher/blinker indicators and want to follow up on this after work today.

Currently all exterior indicators work regardless if ignition is on or off.

Interior blinker indicators only light up when ignition is off.

Hazard indictor light to the left of the steering wheel is not wired up so does not work either way.

Can get photos of my flasher unit and wiring once I get the kick plate off

Our DEC62 built SC does not have the separate E-flasher indicator light on the dash.

Will be interesting to see what you have.

Found another relay candidate in the classifieds, but in used untested condition, so no new box with VW part number. Looks same, but has the Hella part number 91ES4J2 x 18W - 6. Do wonder why the single digit change in the part number....

Terminals are marked:

49a/S

-31

+49

See my primary post in this forum regarding where I have been over the past few weeks.

Here are some pics that I took of my dash wiring and flasher relay. The relay appears to work properly as the exterior blinkers themselves work fine when the switch on the steering wheel is engaged. As mentioned previously, the dash indicators only blink when the ignition is in the "off" position. During my recent engine pull we found quite a few "creative" wiring issues, some of which we rectified, but others, including much of the dash wiring, still need to be looked at.

Wiring around the speedo. I cannot make head nor tails of what is going where here.

You will probably need to find a three terminal flasher that has the correct workings to get it all functioning correctly.

Here is a thread that shows a modern 12 volt relay that might work. If one is running 6 volt it would be still good info, using the 12 volt part number one might get a lead on a 6 volt version of that.....

If anyone pursues that lead, would be very interested in the out come!

Decided to do a search of the WWW for "flasher relay 6 volt 31, 49a, 49" and found a few more results:

Use a flasher relay from and early bay. I have been running one for 20 years and it works fine. The only thing you need to do is add a ground wire, the original used the case and mounting stud as the ground.

My flasher relay is 3 terminal. I am currently running a 12v electrical system on bus.

It should be a 4 terminal, 3 wires and the case mounting stud is ground. There are 2 sets of contacts in it. One is the bi metal that gives the turn signal on off on terminal S and + and another that gives the indicator a switched GROUND for its's function on terminal K and case ground.

Should be grounded thru the mounting bracket shown below.
