I'm waking this thread as I have a question.
First of all - when I searched this out the look of gloom filled my face as I need to fit a new cable in. It sounds like torture.
Unless there's another way....
An explanation.
I have a new 'drift' speedo and analogue to digital adapter for the mini. So you replace the mini cable with this new one and it supplies a pulse signal to the speedo. Anyhow - the old speedo cable obviously works perfectly ok so is there any possible way of joining male-2-male (as it were!). My feeling is 'not' because the in-car bit is designed to plug onto the back of the 3-dial PCB binnacle (L-reg mini) while the adapter is a screw in type.
I have to ask the question because - from the look of the above - it sounds like torture (unless they've changed the law on child labour?)
To add to the misery there's a supercharger sitting in the place where the carb usually sits! (sounds like a weird complaint!).
I wonder if there's an interface thingy that I can push the original male into that turns it into a female......
