Fairplay that car is the bollucks

Right, so your running a RST lump running from a conventional coil. Any mark 4 rev counter with the exception of the EFI should work straight off, the EFI being the only DIS model in the range.

Try another mk4 PCB and if that doesnt work i'd start asking questions about the wiring personally, can't see numerous rev counters being faulty.

Christ Your running the power steering off that, does it actually tick over ok
