Hey all,

Have replaced my blower motor & resistor and putting it all back together. But now I'm at the plug and I'm not sure which wire goes into which part of the plug. 

there are 4 wires:
- Yellow
- Yellow & Black
- White
- Red & Black

And the plug has numbers 1, 2, 3, 4 on it.

Does anyone know which colours go into which number?

Thanks!

It should be pins -

1 - White
2 - Yellow / Black
3 - Yellow

+ - Black / Red (There should not be a pin 4).

And for the panel illumination.

31 - Brown
58b - Grey / Blue.

Thanks both! much appreciated. 

Tried those this morning and still nothing, so I wonder if I've wired the blower motor/resistor wrong 

There is power coming from the black/red.

Did you connect the thick brown wire to ground from the motor itself?

UPDATE: -
So you need to check the wiring from the motor itself to the resistor pack.

Two yellows to the + side of the motor.
One yellow direct from switch position three, and the other from the resistor pack.

And fat brown from the - side of the motor to a good ground connection on the body or the earth crown on the a pillar / inner wing under the left side of the dash.

All sorted in the end! 

Turned out to be an old rusty earth connection. Once I had tidied it up it sprung into life. 

Thanks again!

Excellent news - Glad it is sorted.

Rusty, dirty or loose earth connections probably cause 90% of electrical issues on these older vehicles.
