AMP/Tyco connectors with latch
The AMP automotive connectors used on most IQAN modules also are keyed and
equipped with a locking mechanism. The automotive connector locking mechanism
consists of a different coloured sliding latch, mounted on one end of the connector.
This type of locking mechanism helps to press the plug and receptacle of the
connectors together. This minimizes risk of damage to the pins.

Mating and unmating connectors
C
AUTION
Risk of damage to the units' electronics.
Do not mate / un-mate while units are under power.
Mate the latched connectors as follows:
1 Pull out the wire harness mounted connector's sliding latch.
2 Check that the connectors and pins are clean and undamaged. The pins should all
appear to be flush with the mounting face. If any pins are recessed, push the corre-
sponding wire from the back of the connector to seat the pin properly.
3 Verify that only one face seal (if used) is installed in the module’s connector.
4 Put the two connectors together so that the keying passes into the corresponding
track. Wiggle the connector to ensure that all pins and their mates are aligned.
5 Push the latch in while applying force to the connector shell, so that the two connec-
tors are pressed together. The more pins the connectors contain, the greater the
power which is required to push in the latch.
N
OTICE
Do not rely on the latch alone to assemble the connector!
The force applied by the latch on the keys could damage the module’s connector.
6 Push in the latch completely so that the plastic hooks secure the latch position.
Unmate the latched connectors as follows:
1 Pull out the connector's latch while also pulling the connector away from the mod-
ule. The more pins the connectors contain, the greater the power required to pull the
latch apart. The connectors remain locked together until the latch is pulled out to the
maximum extent. It is not possible to pull the connectors apart before the latch is
pulled all of the way out.
2 Check that the connectors and pins are undamaged. Check carefully the plastic
hooks which secure the latch in its pushed-in position.
3 Damaged connectors must be changed.
