Charger, heater and vacum mounted

This weekend I mounted the charger, the heater and the vacuum system. The Brusa charger hangs under the same aluminum U bar as the Soliton motor controller. The mount is made of two sturdy 50x50x5 mm aluminum angles with two 3x30mm "suspensions" to distribute the load to all four bolts on the Brusa. It also has a small 2mm diagonal angle to support in in the front to back direction.

Still to connect are the control wires the go into the black multi-contact to the right

The front battery box serves as the mount point to a lot of stuff in the conversion. The A2 is a fairly modern car and there are no big areas of metal around the engine compartment to mount things on, Only two aluminum frame bars and lots of plastic (which is now removed). So, the vacuum pump is now mounted onto the battery box using two pipe clamps. The vacuum reservoir mounts to the lock carrier in front of the right front wheel where there is some space left. This means that there is almost a meter of vacuum hose (in fact it is coolant hose) between the reservoir and the vacuum servo which is in the rear left of the engine compartment. I hope the hose will not "eat up" all the vacuum by compressing itself.

The heater also mounts to the battery box with its top mount. Its bottom mount is an aluminum angle fitted to the box that holds the motor controller.
I am getting second thoughts about the heater. It is made from an ordinary steel pipe and it is far from stainless. A couple of days after I had tested the function and watertightness of the heater I emptied it of the last remaining water. Out came rust-brown water. I am not sure I want to get all that rusty water into the heat exchanger in the ACC even though engine coolant is normally corrosion protective. Maybe I will make a new one out of aluminum instead...

The heater (the black cylinder)

It's a tight space

 The wires for the heater goes to the SSR (Solid State Relay) box which will control on/off of the three heating elements as commanded by the Arduino.

More connections go onto the front battery box

The SSRs for the heater...

... connected nicely. Only the control signal from the Arduino remaining.
