I found this PDF on the slot it website.

If I am reading this right, the SCP home analog cartridges come in 2 variants to suit the different track schemes.
2 options:
- convert your track wiring to suit the scp2 
- order the scp cartridge to suit the scalextric scheme.

If you want your cars and controllers to be useable at a club  rewiring your track is the better option.
Flipping  your analog cars' guide wiring would work to fix the direction of travel, but there are drawbacks.
- all visitor cars to your track would go in the wrong direction.
- the guide self centring on some cars would be messed-up (Even if the wires are long enough to be able to swap them over )

There is a SCP cartridge,  the 201BC that has a jumper to remove. (J1)
This being a new controller, you might be lucky and have that cartridge.
Can you tell which you have?

Hi Alan,
this is really interesting to read, I ordered a TruSpeed BP II for my Scalextric Sport track and unfortunately Steve sent a digital one and not analogue.
I'm itching to use it as the scalextric ones are rubbish but am waiting patiently as I had to send it back.

Why are they wired differently? surely clubs started from enthusiasts and would of originally had scalextric tracks.
Is there some type of advantage being wired differently?

Sorry if this has already been answered.

Cheers
Tony
