* If a 12V system is specified during engine configuration then the
engine will be supplied with a 12V only A5:E12 ECM. This ECM provides
the same I/O as the A5:E2v2 the only difference being that the A5:E2V2
is dual voltage compatible.
It is recommended that one supply cable from the battery be used. This
single supply cable should then be spliced as shown in figure 4.4.
Please note that it is the customer’s responsibility to ensure that the ECM
supply circuitry meets the limits stated within table 4.1. For this reason it may
be necessary to increases the supply cable AWG (CSA) in order to meet the
system design criteria.
Note A: Ensure cable splices are made using 14AWG wire and kept to a minimum
length.
Note B: Ensure that the main supply cable is correctly specified in terms of length,
resistance, voltage drop and current carrying capacity.

Note: Diagram shown is an example only of the ECM supply and ground
connection. All Fuses must be chosen in conjunction with the data
shown in table 4.1. Fuses must be rated to protect the ECM supply
cables and not the engine ECM.
