Engine Wiring Harness
Models 107, 124, 126, 201
Engine wiring harnesses will now only be available with a 7-pole connection for the overvoltage protection relay.
When installing a new engine harness with a 7-pole connection into a vehicle with either a 4- or 5-pole connection, it is necessary to also replace the
overvoltage protection relay and the bracket for the control units.
Note:
On models with ABS, connect the voltage supply line for the ABS control unit to terminal 7 of the separate 3-pole connector of the overvoltage
protection relay connector (Figure 6).
The cable connector of the removed bracket for the control units is to be replaced with a new cable connector and secured with cable straps to other
cables in the component compartment behind the battery (Figure 7)
