2019 Jimny Intermittent Rear Wiper Mod Gen4 (JB74)

This would be GREAT!! and Thank you.

I have the Swift wiper switch but for those that have the original one (and also for me) the mod for just intermittent wipe would be sufficient, especially if it is not too complicated and would not require additional cables from the front to the back.

Update time, 

I have (thanks to Martin for pointing it out to me) reconfiguerd the way the realy circuit connects to the Jimny.
Now this is only if you have the later Swift style switch fitted with the INT position on the Rear Wiper.

The original Grey wire I had removed from the block is now put back into position, the output wire from Realy 3, #30 is now spliced into this.

The switch has an unused pin, #1 (zoom in, you can just see the numbers)
 

Corresponding hole in the connector block
 

Flylead with small terminal fitted into the hole. I opened it up with a 3mm drill the went down it with a small square needle file.
 

Connected up to the Relay circuit, Relay 1, #85
 

And the final diagram tweaked to show the update
 

Finaly a video of it in operation

I noticed something that I haven't picked up on in any previous cars.

With the wipers on constantly, when I accelerate they slow down.

When I lift off the throttle, they speed up. I've never noticed this before.

Get yourself one of those volt meters that plug into the cigarette lighter outlet and monitor the voltage there, I suspect you'll find the voltage drops a volt or two when you accelerate and comes back up when you lift off the throttle.

More & more modern vehicles are being supplied with "smart" alternators that allow some degree of control by the ECU and reduce output voltage when the "mechanical load" on the engine increases - it's done to reduce fuel consumption.

How about accessing Soeley's secret menu and watching the voltage from the infotainment screen?

I've answered my own question.
The hidden screen was ranging from 12.2 to 14.8v during normal driving on my commute.

That was with the stereo on mute and only the drls on, with the fan on as low as it goes, so not a massive load.

I suspect I could have got the numbers to change a little if I wellied it.
