Have a look above your thread in the Pinned section, second from the top. Might be of help.

if mine is anything to go by, I didn't find a diagram that exactly matched my model ('88 mayfair) I'm sure there is one, somewhere, but  in the haynes and looking through the stickies there were so many variations I just gave up, the closest sounding one with the right sort of age was i think 'mini special' ? but that didn't match what I had 

 

I pulled it out of the car, spread it out on a table, and continuity tested it with all the various switches and column stalks connected and labelled each end with a dymo printer,  I know that doesn't really help much but with a bit of time and patience (and netflix on in the background) it's not really that complicated compared to a lot of other cars

 

the most complicated bit was the lighting circuit because it goes back and forth from switch to steering column etc

 

main bulk of cables goes out through the big hole in the centre of the bulkhead and (looking at the engine from in front) left around the engine.  other bits (nearside lighting and wipers) goes off to the right, and there's also a little bundle with a load of connectors that goes off that way, then back in through the bulkhead and off to the back of the car.  once back inside, that bundle goes up the near side A pillar, above the door behind the roof lining, down the C pillar behind the strengthening plate.  the window heater breaks off at that point but everything else goes down into the boot 

 

I was assisted by the fact I had labelled about 50% of it as I went along removing it from the car.  and when I pulled the rear loom out I tied a pull string to it for easily pulling it back again

AI’ll work for me. Suggest a Haynes Workshop manual if you can’t get them to download.

 

don’t forget get you need the ones with the date closest to your build date but before.

What you downloading on? Might be a "device setting" ..

I believe this should be the correct diagram and legend for your '92 Carb model. 

 

Routing the Harness is more straightforward than you imagine, theres almost no flexibility or slack in the mini harnesses, and as such it will pretty much dictate the route to you. After the engine section, it will go through a hole in the bulkhead,.. on yours i would think it will go through a hole to the drivers side of the center of the bulkhead, so you can attach plugs to your switches and column.

The section After the bulkhead mounted fusebox goes under the scuttle towards the wiper motor, before going through the bulkhead nearby, there will be a hole -> All you really have now is the wires for the rear of the car, these will go through a small hole near the door check strap access hole... up into the roof via the A pillar and right the way down to the back of the car via the heated rear screen,.. and finally emerging behind the fuel tank, into the rear lights and across the boot floor terminating at the o/s light cluster. (I think!!)

My 1993/4 cars had the wiring loom going along the passenger side floor (RHD CAR)

Thanks for the wiring diagram and other info
