Mk, is there a relay that doesn't require modification or a different way.
Yes, read the link I posted, all is explained on the first page
What car? what engine? is the tacho output coming from the piggyback??
i used a normal relay on mine and it worked fine, just have to be careful connecting them up so you don't damage your stock tacho
Ae86 4agte, also can someone tell me which pin the rpm is on the dash and ecu please
Edit, My bad just saw u have a 86, not sure if its the same as ke70

Na the plugs are different
Ok so if your running an aftermarket ecu then you need to change the output signal type from ur ecu. I bought a dakota digital off ebay and im just waiting for it to get here. But maybe you could jig some shit up like it.
Check it out

If it doesnt work just ebay dakota digital and see the universal signal interface
Ok cheers
