you know how theres a tacho pin on the diagnostic connector (EF/EL)
is there a speed pin somewhere too?

also, has anyone ever put a 100mm CCFL tube in the dome lamp before?

...please explain mate. What is it?

stands for Cold Cathode FLuorescent, there like mini fluro tubes,

click here for details,

just wondering if they'll fit, cos the dome lamp cover is around the 10 cm mark in length if im not mistaken?

i suppose it would give more of a cool white compared to the warm brown colour of the standard globe
