6.10. THE SEPERATE CABLES

Assorted wiring harnesses
In order to simplify construction as well as installation we have decided to equip the harness with several multi-connectors. This greatly simplifies the eventual removal of any of the front wings and allows the removal of the engine by undoing just one connector.

Defroster and wipermotor:
> 311 (2x) Earth
>93 to blower
>91 to wipermotor

Headlamps x5 and x8
This 4 core cable has to be connected inside the headlamp to the Duplo or H4 bulb and the optional sidelight.
The wires go through the headlamp housing to the outside and enter the engine compartment via a to be drilled hole of 7 to 8 mm diameter. Once the wires are fed through the hole, the connector can be installed. Refer to the already installed counterpart of the connector to see which wire has what position.

Indicators x4 and x7
This harness is made to connect the indicators, which sit on top of the large front wings, but it can also be used if cycle wings are installed. First, make the connections on the indicator side. The eyepiece goes under one of the mounting screws of the indicator housing and the two round shaped connectors fit to the indicator itself. Because this connection will be exposed to all possible weather influences, you need to carefully insulate the connections.
Fixing the cable to the inside of the wings using Sika Flex turns out to work out fine.
This cable is also fed through the front into the engine compartment after which the connector can be installed.

The engine harness
The engine harness is used to connect the common parts of the 2CV engine block. This part of the harness is to be built so it suits your needs. As a rule of thumb, only the oil pressure switch and the ignition points are connected. Many people prefer to also include additional equipment like the oil pressure transmitter, temperature transmitter as well as the fully electronic 123 ignition. Our wiring set contains the following parts:
Connection for the oil pressure transmitter, consisting of two wires, The transmitter has both a contact for the warning light >87 (WK) as well as for the gauge >187 (G).
If you only wish to use the original oil pressure switch, you have three options: Most sensors are equipped with an M3 screw terminal however; later types have either a “Faston” connector or a 3 mm connector.

Connection for the temperature transmitter
The transmitter is fitted in the oil carter, replacing the drain plug. To be connected via  >86

Points
The original points are connected via to >1

123-ignition
The 123-ignition is always delivered including the wiring: a red, a yellow and a black wire. As this wiring also runs via the multi connector, the relevant brass connectors (part of the wiring set) need to be crimped on the wires.

From 123-ignition to multi connector:
Red lead >15  +12 Volts from ignition switch
Black lead  >1  “-“ connection from the ignition coil
Yellow lead  >123  “+” connection from the ignition coil

Be sure to properly fasten the harness. We suggest guiding the cables through the ventilator housing the same way as Citroën originally did it. Be sure to use a proper size grommet or gaiter to protect the wiring from the steel ventilator housing.
