Fuse Boxes
by Karl von Salzen
70, 71, and 72 fuse boxes are different.
Each year has its own part number:
411 937 505A is for the 1970 bus.
411 937 505B is for the 1971 bus.
411 937 505C is for the 1972 bus.
Side-by-side, the B and C appear
identical. The A is totally different.
The original A was yellow and it split
down the middle! VW got smart and made it out of white material in
the middle of the 1970 model run and it does not
split.
I believe I have one good used A fusebox
left...... I know I have a B and a C, they don't
split.
BTW, the D is for the 73 411 and the E is
for the 74 412. The difference is in the bottom, where the relays
are.
The 1971 B fuse box uses 111 953 227A turn
signal/hazard relay.
The 70A box uses the 411 941 583
lowbeam/highbeam relay.
From vin 210 2000 001 to 210 2300 000
The 71B box uses the 411 941 583B low/high
relay,
from vin 211 2000 001
If you do not have the optical horn [high
beam flasher] in your turn signal switch (you do!) then the 70
relay is 411 941 583A and the 71 relay is 411 941
583C.
