Type: 6-pole electrical connector
Contents: Male and female connectors
What Does the Multi Plug Socket Do?
The 6-pole multi plug provides a detachable electrical connection between sections of the vehicle wiring.
Its six-pole design allows multiple electrical circuits to pass through a single connector while keeping the wiring organised and providing a connection that can be separated when servicing electrical components or the wiring loom.
Why Do Electrical Connectors Fail?
Electrical connectors on classic Porsche models can deteriorate after decades of heat, vibration and previous maintenance.
Common problems include:
- Brittle or cracked connector housings
- Broken retaining sections
- Corroded electrical terminals
- Loose connections
- Heat damage
- Previous wiring repairs
- Damaged or incorrectly fitted terminals
A deteriorated connector can cause intermittent electrical faults even when the surrounding wiring appears serviceable.
When Should It Be Replaced?
Replace the multi plug socket if the housing is cracked, melted, badly worn or no longer holds the electrical connections securely.
If diagnosing an intermittent electrical problem, also inspect the terminals and surrounding wiring for corrosion, heat damage or broken conductors before replacing the connector housing.
Checks Before Installation
Before fitting, check:
- Existing connector matches the 6-pole configuration
- Wiring terminals are clean and undamaged
- Wires are securely attached to their terminals
- No corrosion is present
- Connector orientation is correct
- Wiring is installed in the correct terminal positions
Record the original wire positions before dismantling the existing connector to avoid incorrect reconnection.

Why replace this relay?
Loss of intermittent function — the most common symptom: intermittent (delay) wipe stops working while continuous speeds still operate. Many owners find the delay knob produces one sweep only or nothing.
Wipers stuck on / won’t stop — relay contacts or internal timer failure can leave wipers running or behaving unpredictably. Forum reports show both “wipers won’t turn off” and “wipers run continuously” symptoms tied to the relay or associated wiring.
Intermittent clicking / no response — relay may stop clicking or click but not switch the motor circuit due to worn contacts or internal failure. Swapping relay is a common test.
Common issues & fault causes
Worn internal contacts / timer fault — relay internals degrade with age and use, causing loss of the pulse/interval function.
Corroded connector or fuse/relay carrier contacts — poor connection at the fuse/relay panel can mimic relay failure; cleaning contact points often fixes intermittent faults.
Related component faults — sometimes the wiper stalk/switch or the wiper motor itself causes similar symptoms; common troubleshooting is to test/swap the relay first, then check the stalk and motor.
Shorts / blown fuses — seized motor or wiring short can blow fuses or overload circuits; a failing relay can also cause abnormal current behaviour.
