Lead marking
| Lead marking |
The leads are marked with a three-part lead code, e.g.:
P15-5 YE/GY 2.5
where :
The first part (P15-5) is a position number
The second part (YE/GY) is a colour code
The third part (2.5) is the lead area in mm 2
| Position number |
All leads have an alphabetical designation followed by an individual number.
The letter indicates the group of systems to which the lead belongs:
| • |

The number is individual except for:
| • |
15 = +15-supply
|
|
| • |
30 = +30-supply
|
|
| • |
31 = ground
|
|
| • |
54 = +54-supply
|
|
Leads with the same letter and number, e.g. E110, E110-1, E110-2 etc., generally belong to the same function.
| Colour code |
The following colour codes are used in the wiring diagrams of the manual. The colour codes can also be used in combination, e.g. RD/BU, GY/WH.
As of M01, dual-colour cables have been introduced with at least two colour fields of each colour. Some small wiring harnesses may still have the old type of colour marking.

| Lead area |
Indicates the cross-sectional area in mm 2 and is of immediate importance for the lead's current capacity.
| Resistance to temperature |
As of M00, the front harness and engine harness of Saab 9-3 have a new type of cable casing with a greater resistance to temperature. When cables in these harnesses are replaced, cables with the new type of insulation must be used.
