MG MGB and MGB GT Tech Talk
As I'm removing the sequential seat belt wiring mess, I found some interesting connections. Did the factory solder the brown wires and tape them up with super-sticky electrical tape? And I found black wires stuffed into a rubber tube with a rubber plug in the end.Factory?
The ground wires in your other picture are for real, but I don't remember ever seeing brown done like this! They are hot all the time!
The brown wires are not factory, not that I can remember for our 77' anyhow.
The black is factory.
Where are those brown wires looks like behind the console?
If you go to Advanced Auto Wire site you can find color diagrams for your year. Those connections will be identified by a dot on the diagrams.
I've noticed the "dots" on all wiring diagrams, and looked for something more technical for a connection. I'll go for the black(ground) wires, but I think one of the PO's did the brown(hot) wires. Maybe?
On the Advanced diagram for 73/74 US Market, they show the intersection of the 5 brown wires located by the alternator, starter, starter relay, and ignition switch. I guess that's to make it simpler to understand where all the wires go. But really they're taped up inside the loom behind the glove box!
Is that where the factory had originally placed a disconnect for shipping? I have a plastic rectangle connector instead of the soldering. It think PO removed the connector and soldered the connection.

Those factory disconnects are usually located near the fuse block.
