Looking for a 12V source under the rear boot floor, to power a fan to cool the DC-DC Converter and On Board Charger, only during Slow Charging.

From the circuit diagrams it appears that 12V is available on Connector E-03 when the On-Board Charger Relay is energised.

Relay Pin 1 Violet, to A-107 Pin 8, Violet to E-03 Pin 22.

1) Can anyone confirm this is E-03 ? The 3-D diagram of pluggery to the OBC and DC-to-DC Converter pluggery is hard to interprete.

2) Is it safe to unplug E-03 with the key out of the "ignition" ?

3) How do you insert an image, I can't find the Help on this forum ?

Yes, but remember the OBC is also active during driving (12V aux charge).

Btw: E03 on the OBC is a 13pin plug, there is no pin 22, maybe a typo as A107 (8) leads to E03 (2)?

1. Yes that is E-03. double tap typo as it is E-03-pin2.

2. i might recommend to disconnect the 12V aux battery while rooting around trying to dixconnect the E-03 as there is a hot all the time 12V feed that may not like getting bounced (break 'n make) during the struggle.

3. Images. Need to use the img tag and the link must be to a hosted image file, eg .png, .jpeg, etc. The image file may be found at something like shared or embed button on gogle drive, although i couldn't find it.

Thanks Kevin

1) Yes my typo for the E-03 pin.

3) Am I missing something, is inserting an image that complicated ?

I had seen the
icon.

My full Google Drive link is, less the https prefix:

://drive.google.com/file/d/1TKND1mnvkGlJbk2yt21aK0ZII0sUqI6R/view?usp=share_link

Your suggested link is:

<iframe src="https://drive.google.com/file/d/1TKND1m ... 6R/preview" width="640" height="480" allow="autoplay"></iframe>

Mine says view? your link says preview?

And I have to remember the format of adding the image pixel size etc ?

Or is GoogleDrive the wrong source for this forum ?
 
Sorry for the confusion--as an example i posted the embed or share link that i found on GD when i went to look at your photo, but it didn't work for this forum.

So then i downloaded it and saved it to my imgur acct (to host it), then used the image link button in the forum message toolbar and the image did show up.

As the picture owner it seems that you should be able to share it from GD, but it will need to be a .jpeg or .png, etc. filename in the url to be placed here in the forum. It's not complicated but GD seems to want viewers to log in in order to see anything.

I've attempted to fix many image URLs in my years as moderator of various forums (but not this one), and Google Drive has to be the least friendly for hosting images that you want to use on a forum like this. The URLs are ridiculously long (like kilobytes) and well hidden (though that's not unusual).

The most commonly used and user-friendly option is Imgur. You still need to dig a little to get the actual image URL, but you soon get used to it. Exactly how to get the URL is unfortunately browser specific, or I'd spell it out here. Look for something like "open image in a new tab" or "copy image URL". You should end up with a URL that ends in something like .jpg or similar, not html.
