Rear wiper help Needed

[LM3929]

I an trying to wire up a rear wiper motor to the switch in the frt.

I can find all sorts of wiring diagrams for the 84 and up models but nothing for an 83 and down.

My Frt. Switch has 3 poles not four like the later models does anyone have that section of the wiring harness or can pull their switch down and post or send me a picture?

edit ...... the right switch has four tiny connectors

Thanks Lorne M.

I went back to 1975 and still found a four pole switch.

53 red/black to fuse 14
53a red/black to motor
31 brown
31b brown/white to the motor in the rear

That's the only mention of it I find in the factory wiring diagrams that I have.

I would still like to see a picture of someone's rear wiper switch pulled down to see where the wires actually go.

Anyone

Thanks Lorne M.

Hi, Lorne, does your switch have the following terminals ?

31B
53A
31
53

No my switch only has three tabs the fourth is jumpered to one tab on the same side.

Am I correct to assume that Porsche doesn't pre-wire the rear wiper switch behind the dashboard?

Thanks

yes, I haven't found any cars so far with the extra wires.

I have had two fellows here makes but the two harnesses needed so that mine would look original.

if you have a/c then the rear condenser has a cut out section
