Lead markings

Lead markings

Leads are marked with a code consisting of three parts, e.g.:



P15-5 YE/GY 2.5



where:

The first part (P15-5) is a position number

The second part (YE/GY) is the colour code

The third part (2.5) is the cross-sectional area in mm 2

Position number

All leads are provided with a letter designation followed by an individual number.

The letter designates which group of systems the lead belongs to:


C C omfort Systems

D D iagnostics

E E ngine Systems

G G earbox Systems

I I nstrumentation Systems

L L ighting Systems

P P ower Supply Systems

Q Anti-Theft Alarm

S S afety Systems

T T elecom Systems

V V isibility Systems

W W arning Systems

X Other systems (e.g. bus)


The numbers are individual, except for:


15 = +15 current

30 = +30 current

31 = ground

54 = +54 current


Leads with the same letter and number, e.g. E110, E110-1, E110-2, etc. usually belong to the same function.

Colour code

The following colour codes have been used in the wiring diagrams in this manual. The colour codes can also be used in combinations, e.g. RD/BU, GY/WH.

Dual-colour cables have been introduced from M01 with at least two sections of each colour. Certain smaller wiring harnesses may still have the old type of colour marking however.

Cross-sectional area

The cross-sectional area of the conductor is specified in mm 2 and determines the current that the cable is capable of carrying.

Thermal stability

The front harness and engine harness have a new type of cable sheath with greater thermal stability on Saab 9-3 from M00. Cables with the new type of insulation must be used when changing cables in the engine harness.
