God that puts Let's see, that is because either is not put on the correct cable or that the clock is not prepared for four -cylinder engines.
Normally in four -cylinder engines, two spark jumps are produced by crankshaft return, with the exception of the Electronic Dis lit that work with loss of
spark (eg Opel Astra F 1.4)
instead of the traditional ignition distributor, which carries the highly screwed high coil somewhere in the chassis and linked by the high cable and those of current and mass.
In the case of the ignition, each coil carries a four -pin connector that receives half of impulses that the engine (that is why it carries two coils)
if your tachometer has no impulse tar, you would have to buy one that would wear a tarum or one suitable for an eight -cylinder engine. (You would have to go to Tunning, or competition, or buy it X Internet in the USA)
Anyway, the car would have to see you can trust 100% of what I have put you.
