Basically i've bought a Fiesta Turbo with a cosworth engine conversion.Its the black one that was on e-bay.

My problem is that the rev counter doesnt work full stop.The guy i bought it from said that due to different coilpacks between the standard FRST and cossie meant that the counter wouldnt read properly and hense waseant wired up so i am wondering is there a solution to this atall?

Thanks in advance,

Colin.
