MSmax-powerbox

 

Msmax used my electric-circuit to make a compact box.

This box came to the market without the pump plugs. To connect the MSmax box to the plugs I made this page.

 

Here you can see a 10-pin power-box

 

First you need to go to the dealer to order these items

 

For the 8-pin plug:

1 x 3A0 973 734 housing
1 x 3A0 973 834 housing
4 x 000 979 129 pins (is inclusive with wire)
8 x N 906 844 05 pins

 

for the 10-pin plug:

1 x 1J0 973 735 housing
1 x 1J0 973 835 housing
5 x 000 979 129 pins
(is inclusive with wire)
10 x N 906 844 05 pins

Further you need a cable with four vanes (4x1,00mm2) to connect the box to the pump plugs.

 

First cut the 4 wires. this will create 8 wires with 8 pins.

The put the pins in the male housing.

Now connect the wires of the cable for the power-box to the female housing pins.

2 on 2, 3 on 3, 4 on 4 and 5 on 5.

 

 

Now put the pins 1 on 1 in the female housing.

On the pic below you can clearly see the wires of the power-box cable beside the yellow wires of the pump plugs.

 

 

Now assemble the powerboxwires to the power-box by using this diagram.

 

 

Adjusting

 

To adjust the resistance of the box you need to measure the value between A and B.

 

Start with 170ohm and turn down the resistance with small steps

I stopped at 160ohm. This is a good value for my car.

 

Never measure the resistance when the box is on!!

You will measure a faulty resistance value!!

 

The power-box will performs best with:

- a closed EGR,

- a diode for Mass-air-flow meter and

- a diode to boost the turbo pressure (or use a bleed-valve if you don't have a MAP sensor).

 

If the ECU registers a fault code the glow spiral will blink. Just restart the motor and the blinking stops.
