Introduction
This section details the allocation of wire numbers and the
identification of wires in the wiring harness.
Fig 14. Typical Wire and Harness Number
K
Fig 14. ( T C-20) shows a typical connector and wires.
Each wire has an individual identification number
permanently marked on it, at regular intervals along it's
length.
The number stamped on the wire shown in K Fig
14. ( T C-20) identifies the following:
Table 3. Wire and Harness Number Identification
Ident. No. Description
B If applicable - The colour of the flying lead that the harness wire should mate with. For instance, if wire 819
from harness 719/37100 mated with a flying lead coloured black (colour code B) then the number printed
on the wire would be B-819 9/371.
819 The wire's unique identification number. The wire functions and numbers allocated to them are consistent
through out the JCB range of products.
9/371 The part number of the harness that the wire originates from. If the harness part number is 719/37100, the
number printed on the harness wires will be 9/371 (71 and 00 are common numbers and therefore deleted).
