5 XF 95 series Removal and installation REPAIRING WIRING 2.5 FITTING AN ELECTRICAL BUFFER CONNECTION A buffer connection is made when at least two wire ends must be connected to one another. This may be required because of a wire repair or if a wire is to be added to a connection. Note: When adding a new wire to an existing wire, both wires must be of the same thickness. If part of the existing wire is to be removed, try to make sure that the wire number can still easily be found on the wire. The contact crimping part (1) is the electrical connection to the stripped wire part. The central stop (2) is a limiter, preventing the wire to be connected from being inserted too far.
The insulation is a crimp insulating sleeve with glue layer (3) which, after heating by a blow drier, will offer protection against unwanted electrical contact and corrosion. 3 There are three different buffer connectors available: red, blue and yellow. Depending on the wire thicknesses to be connected (and possibly the number of wires to be connected) a specific colour must be used. 3 1 1 3 2 - red diameter 0.25 - 0.75 mm 2 E501489 - blue diameter 1,0 - 2,5 mm 2 - yellow diameter 4.0 - 6.0 mm 2 Connecting more than two wires to one another is not recommended. The glue layer of the crimping insulation is not sufficient to seal all resulting gaps.
So this is certainly not permitted outside the cab. 200303 2-17
