Hello

Does anyone know what the below wire could be for?

The wire in question tees off the solid green wire below the steering column, which runs alongside a solid purple and solid red.

I bought the car like this and am putting it back together, but there are some mysterious loose ends!

Possibly a radio fuse? Where does the loom end go? Can you chase the wire?

Solid Green would be live with the ignition at position 2 so I'd say someone has put that in there to power a CD / Radio or something like that.

Probably not the best way to do it IMO.

That's what I thought too, I have a loom from a 94 Italian Job with the inline fuse and solid green wire in this location. It worked so we didnt question it.

Green is a switched (via Ignition Switch) fused wire.

Purple is Fused constant Live.
Red is a feed from the Headlight Switch to the Parking Lamps and Instrument Lights or to the Dimmer if one is fitted.

Ok thanks a lot for your replies. I’ll just ignore it (or remove it).

I was just checking that it wasn’t something standard which I was missing.

The extra inline fuse is either over protecting the switched ignition circuit with stop lights, reverse lights, indicators etc. or under protecting the radio just depending on what amp fuse is in the holder.

Lurking in the same vacinty should be a light green / white terminated wire that is more suitable IMO. That wire works off ignition position 1 and 2 and isn't feeding any 'mission critical' circuits. Put in an inlide blade fuse / glass fuse just depending on the power needs of the accessory you want to run for added protection. That feed can also act as a good trigger for a relay if you want a bunch of stuff behind the dash like CD players, lighting and the such albeit remember it will draw power at ignition 1 so could drain the battery quickly if the cabin is like a disco! ?

I usually do fit fuses on anything electrical. The loom I mentioned above is lying in a box on a shelf in my shed, the shell was too far gone for my bodywork guru so we stripped the car bare and I've used most of the relays etc for my 93 Sprite.
