My flasher broke down and I got a different replacement brand. The original was marked as 31 to ground 49 to 12 volt supply switch and 49a to indicator switch.
The new replacement have marking as: E, B, L
I deduct that E to ground, L to 49a and B to 31
Can anyone help provide some pointers where the "original 31, 49, 49a" should be connected to the replacement flasher?
Thank you

Re: New flasher pin marking different?
Confirm. Any brand flasher for modern cars can be used. They usually have markings on the pin as: E, L, B
E is the earth (ground) connection equal to VW original pin 31
L is for load connection equal to VW original pin 49a
B is for "battery" (12 volt) equal to VW original pin 49
Make sure that it is rated for minimum of 23 Watt x 5 or maximum rating for 120 watt
By the way, I have a 1975 dual port 1600 that uses an original VW flasher with markings as: E, L, B
E is the earth (ground) connection equal to VW original pin 31
L is for load connection equal to VW original pin 49a
B is for "battery" (12 volt) equal to VW original pin 49

Re: New flasher pin marking different?
31 is ground ("earth") - the connections listed in your second post should work, but not the ones in the first post.
Other terminal markings you may encounter are X, P, and L on a 3-prong flasher or X and L on a 2-prong. These flashers did not have a ground connection,
3-prong VW flashers have either the 49, 49a, and 31 or +, 49a and 31.
4-prong VW flashers had 49, 49a, KBL and 31 or +, 49a, KBL and 31. KBL was an auxiliary contact that fed the indicator lamp on the dash; when it dawned on them that the indicator lamp would work fine (although in alternation with the external lights rather than in unison with them) if the KBL wire were simply piggybacked onto 49a, the KBL contact was dropped c1971.
To sum up, power goes to + or 49 or B or X
Ground connects to 31 or E (or to nothing on many flashers)
If there's a KBL or P terminal, it's where the wire to the indicator lamp should connect
The output to the t'signal switch comes from 49a or L
If there's no KBL or P, also connect the indicator lamp to 49a or L. Typically the first thing to go bad in the original 4-prong VW flashers was the KBL feature, often they'll function just fine as 3-prong - simply piggyback the indicator lamp wire to 49a and leave the KBL terminal unused.
