speedo problem
 

hello everyone,

im a new member to the site im currently on my second rx7 type r i bought as a bit of a project needs a fair bit of work doing to it.
One problem i do have is when i bought the car the speedo didnt work on further investigation it turns out it has a chip wired into the back of the speedo to convert it to MPH which i do need as i live in the UK, when i removed the chip the speedo worked fine but in KPH looking at the wiring on the rest of the car i reckon it was probably wired in wrong could anyone tell me the colours of the cables it needs to be wired into .

cheers
