Problems understanding wiring diagram

[True Brit]

I'm attempting to fit a radio in my '72 2.4E, and I don't particularly want to run new wires from the fusebox to the radio unit (like to keep things as tidy and original as possible).

Now there are two 'odd' spade end connectors in the loom behind the radio cutout, and I was wondering if these are meant for the installation of a radio. I'm afraid I don't have the wire colours to hand at the moment because I'm at work, but if anyone can enlighten me as to whether these are the right wires, and which colour is which, then I'd be grateful. Either that or I'll have to buy a multimeter on the way home (yes, I know I should have one in my toolkit!).

Check them with a VOM. You are looking for +12V switched(on when key is in the run position/off when the key is in the off position). You can ground to any conveinient chassis ground or brown wire. A normal radio or head unit does not draw much current and so should not over load the wires. A separate amp should always have its own line to the battery. Properly fused of course.

The spades/wires may be unused sections of the wiring harness like for the optional front gasoline heater. Do a search under "Radio" on this BBS and then look at threads: "76 Radio Wiring..." and "Vielen Dank Roland...." .

Hello

the odd connectors are blue and red/yellow ( togehter with a black one ) wires to run the supplement gas heater.

Red/Yellow is fused with the accesory socket, blue is normally open end.

Behind the ashtry are 3 spades welded to the bulkhead to provide ground.

You also will find illumination and ground on the bulb holder from the ashtraylight.
( Don´t pull the rubberboot as it takes time to refiddle it back in )
