unknown plug

[reedreed]

Could anybody explain this plug behind brake booster. It has just single wire (green/white traces) with 12v (ignition on). What is this for?

What year is your car? There are two groupings of wiring for our cars; 72 and earlier is different from later.

73, 3.0 CSI (D-jet)

Probably the hook up for the electric chokes, electric idle valves for carbs In the wiring system regardless if you had carbs or fuel injection, just not used in the FI cars

Thanks, Rick

There is a relay to the starter there if you have an automatic.

You´ll find this as connector "37" in the wiring diagram

In my ´74 CSI it looks like this:

There are three connectors (all solid connections no plugs), for the the centre one there`s only a connection on one side.

Hello Thomas- can you share your 1974 djet and key schematic with me?
It is quite different from the early djet schematic and I would really like to have both on file.
I would really appreciate it.

Dear Don,
I sent you a copy!
The difference is due to the fact that the early versions use a dedicated resistor "22" to lower the voltage at the ignition coil once the drive started.
One base of the resistor is used as a terminal to connect two wires.
Whereas the later versions use the resistor cable. To connect the three wires a separate terminal was installed.
Regards
Thomas

Same with carb coupes in 1974.
