1 Connect cables to electrical center (A12).
To do this, cut the existing cables from the tachograph approx. 10 cm from the plug, connect to the following cables and strip the insulation.
Solder on cables from the tachograph and insulate (arrows).
Two brown cables from tachograph pin 1/A5 and 1/A6 (circuit 31) to plug (A12.3) pin 4 of the electrical center (circuit 31).
Pin 1/A1 (circuit 30) (red/yellow cable) from the tachograph to plug (A12.4) pin 6 of the electrical center (circuit 30).
Pin 1/A3 (circuit 15) (black/blue/green cable) from the tachograph to plug (A12.4) pin 5 of the electrical center (circuit 15).
Pin 1/A2 (circuit 58) (grey/green/red cable) from the tachograph to plug (A12.5) pin 10 of the electrical center (circuit 58k).
Route cables so that no abrasion and short-circuits are caused.
