High Load wiring Locations

[Tom D]

I've been trawling the forum, looking for the wiring locations for the Aux wiring. Can't find what I am looking for.

I need to rewire the signal to the rear relay for the 500A circuit, I need this co come on with the ignition. I'd prefer to splice into the loom under the seats to save removing my drawer system to access the relay directly. But I need some better information.

Sadly I can't find anything in the workshop manual.
I have seen an image that shows the wiring locations but can't find it now...

Any help appreciated.

A slight update: I have discovered that there is a pre-relay relay.... So I should be able to intercept it there under the seats, this will make life a lot easier..
I'll update once I have figured it out for sure.
