Adding circuit to fusebox (no add-a-circuit tap)

[simion_levi]

Has anyone successfully added a circuit to the Octavia 3 fusebox without disassembling the whole dashboard? That is to say, pushing cables with JT/JPT connectors in to the back of the fusebox, not using the add-a-circuit fuse taps.

 

I've wired in my OEM reverse camera recently, it's the correct loom with a JPT connector for 12V so I'd like to connect up to fuse position #18, as it should. I've had a bit of a poke around, but I couldn't see a way to get the fusebox forward enough to release the purple locking strip, Some success stories would help give me motivation to return to it another day, rather than leaving a temporary bodge in place!

 

I've shamelessly borrowed a couple of photos to demonstrate from our Cupra friends at:

The Octavia has a crossmember passing straight over the large white shield/connector near the bottom of the box, but this looked to be integral to large parts of the dash.

Yeah, you just pull the radio out and the surround, pop the 3 fusebox tabs and pull the fusebox out. Push the new power cable into the back of it and ground somewhere appropriate.

Great, thanks Sasha - should've known if anyone had done it, it would be you! I'll have another go at it then.

In case this helps anyone else: 

 

I did this a few weeks back and spent ages buggering around trying to get the JPT fitted connectors on a couple of looms I was adding to latch into the fusebox. In the end I had to give up and rely on the secondary lock (the purple strip) to hold them in place. It'll be absolutely fine, but frustrating and a job not done 'properly'.

 

Well today I got hold of a similar fusebox from a scrapped car and very quickly realised that JPT will never latch. MCP 2.8 connectors are needed instead!

 

Photo attached - JPT (TE Connectivity AMP Junior Power Timer) crimp terminal at the bottom - I've used these in previous generation fuseboxes (Octavia MK2 etc) and received several ready made looms for current MQB models, to fit to my Octavia MK3, with them attached - so naturally thought they should fit!

Whereas top connector, crimped to a cable, is the MCP 2.8 (TE Connectivity AMP Multiple Contact Point) connector that is actually required in fusebox Octavia 3 and other MQB models for minifuse connection. Note different latch position.

I will say that the larger JT terminals still seem to fit and latch in the standard size fuse positions.

I'm trying to plan my fuse box addition before having seen the fixed ix but how did you realease the box? I see 3 black tabs and something pink - what about those?
