still dont understand wire diagram c2 rear wiper!

[bigpino]

I'm considering installing c2/4 window with wiper, however, I got a 3.2 harness. I got a wire diagram of the c2 rear wiper electrics, but dont understand it since it's a one pager and I miss some info. Somebody no more about it?

C2 rear wiper connector (2 x 3 terminals)
1) Motor (and tag k15), is that all ways?
2) nc
3) nc
4) button
5) button (and tag N26), is that hot in run?
6) Ground point.

3.2 harness
red - always hot
red/blk - hot in run
red/blk - swithes to hot in run (but where is that diode installed?)
brn/wht - swithes to grn
brn - ground

OK,
Here you go:
12V battery power from Terminal 30 comes from a connection point splice after Fuse 12 (15A) and goes off sheet 2 at tag K15 to tag F74 on sheet 8. This always hot 12V power is routed to the Rear Window Wiper Motor terminal 53a via pin 1 on the 2 x 3 terminal plug on a 1mm red wire.

12V switched power via relay R33 from Terminal X also comes from a connection point splice after Fuse 28 and goes off sheet 3 at tag M26 to tag E75 on sheet 8. This switched 12V power is spliced into the Rear Wiper Switch button via a .5mm violet wire. The other splice connection goes to the Rear Window Wiper Relay terminal 15 via pin 5 on the 2 x 3 terminal plug on a 1mm violet wire.

The other wire from the Rear Wiper Switch button is a .5mm green wire and it goes to the Rear Window Wiper Relay terminal L via pin 4 on the 2 x 3 terminal pug.

The Rear Window Wiper Relay is grounded on terminal 31 by a 1mm brown wire via pin 6 on the 2 x 3 terminal plug. This brown wire is spliced at terminal 31 and the spliced connection goes directly to terminal 31 of the Rear Window Wiper Motor.

Finally, there is an interconnecting 1mm green wire that goes from terminal 53 on the Rear Window Wiper Relay directly to terminal 53 on the Rear Window Wiper Motor.

Pins 2 and 3 on the 2 x 3 terminal plug have no connection.

This is from the 1991 schematic, the colors and terminals may have changed somewhat.

ok, thanks Mark. I think I got the c2 part right than.

How about the 3.2 part? Do you know where this external diode for the wiper motor is placed? I know that the c2 version got it build in. This diode is connected to rear wiper switched power/button and than I only need the easy to find 'always hot', 'switched power', and ground.
