Hello,
I own a C3 petrol and i want to upgrade it with an auxiliary cabin heater like on diesels.
I bought the heater and connector for it from a parted vehicle.Later i found,that i will need a BCP3 relay/fuse module too.
I will buy it in some days, BUT:
Can somebody help me with the portion of the wiring diagram,that shows where these wires are going from BCP3:

-8095;
-CM15H;
-CM15B/CM15H;
-8096;
I have Lexia and I know how to activate the heater after the connection is done.
Thanks in advance

Hi


The diesels additional fuses were controlled by the engine ECU.

You won't be able to do this with a petrol ECU. You don't get the options on the petrol ECU.


I suggest you just wire up to the battery and ignition with a relay, a fuse and a thermostat, completely independently of the ECU control.
