 Optionally the output level can be adjusted to 12V (e.g. for TDI control units). Connect the open solder bridge for this purpose.

+===== Connection =====
+==== Assignment ====
+^ Color ^ Function ^
+| Red | Power supply 12V |
+| Black | Ground |
+| White | Signal |
+==== Fuse ====
+In itself the Speedpuls is short circuit proof. However, there is a possibility that the connection cable could trigger a short circuit due to a defect.
+Therefore, the Speedpuls must be protected by a fuse.
+If the power supply of the Speedpuls is realized via a control unit, then it should be ensured that the control unit is fused accordingly.
+No matter which voltage source is used, it must be ensured that a suitable fuse is used.
+It is recommended to use a fuse at the power supply. Otherwise there is a risk of damaging the control unit in case of a short circuit. The fuse should be placed as close as possible to the voltage source.
+The Speedpuls can also be connected with its power supply directly to the fuse box.
+Suitable slots would be:
+^ Slot ^ Fuse ^ Terminal ^ Description ^
+| G3 | S12 (20A) | terminal X (ignition plus, but relieved at starter) | supply plus for air conditioning |
+| G2 | S18 (10A) | terminal 15 (ignition plus) | supply plus for GRA (cruise control) |
+==== Unsuitable voltage sources ====
+Connecting the speed pulse directly to the battery (terminal 30) is unsuitable.
+Even if the current demand is in the mA range, this current is permanently drawn at terminal 30. Even if no signal is detected.
+The speedpulse has no disconnection here.
+===== Older documents =====
+For historical reasons, the old documentation is still available here.
