Replacing some wiring on the Multifunction Switch

[TEJOLX47]

Hi everybody,

I am trying to repair my Multifunction Switch that broke on the plastic handle.
Upon disassembling, I notice two pairs of wires inside the metal rod in bad condition (copper exposed).
So I removed them to replace for new ones.
However, the rod is very narrow so I have to go for "thin wires".
These wires connect the handle via the metal rod to the Multifunction mechanism (25cm), therefore I believe they will never carry a lot of load.
But I am not an expert.
Do you think an AWG20 silicone wire will be OK?
Many thanks and happy Easter.

Be careful, consult the wiring diagram for pagoda on this forum.  None of the wires that go to the steering multifunction switch are narrow, all of them handle an important load.  If your car has the high/low beam switching on the floor, then those wires which are the heaviest are not present on the steering multi switch (each 2.5mm2 equal to AWG 14-12.

The rest of the wires are of important section.  All are 1.5mm2 which is AWG16.

So do not go with AWG20 which equals to 0.5mm2.  You will fry the cables that feed either the wiper motor or the turn signals.

Hi Leonard,

Thank you very much for your help.
My car is a US late 1970 model, with the high/low beam switching on the floor, and the wires I am talking about are those inside the chrome lever (see picture attached), connecting the handle to the contact plate.
The originals are +/- 1.3mm in diameter, so probably AWG 16.
My concern was about thickness, once normal Awg16 do not fit inside the chrome lever (it's very narrow).
Also, my diagram is slightly different from yours and do not carry info on wire colors and gauge.
So I am going for the awg16 as per your recommendation. With a thinner cover.
Many thanks

Why don’t you try to keep those original wires and put a new Thermo shrink jacket on them.?  Use some silicone grease which is non conductive to help sliding the cables Inside the tube back.
