edviss Posted March 13, 2021 Share Posted March 13, 2021 Hi All, I am currently wiring my 2jz non vvti with ecumaster classic. As it is na-t, I am getting rid of distributor and doing smart coil conversion. With smart coils igniter is not in use and its getting deleted. Where do I pin tachometer signal from? On ecumaster there is a pin 20 on grey plug - aux 4/ tacho. Do I pin this to body loom that sends signal to cluster? Thanks, Ed Quote Link to comment Share on other sites More sharing options...
Mike2JZ Posted March 14, 2021 Share Posted March 14, 2021 Yes connect it to the tach input on orange 36 pin interior plug. Don't forget you will need to bypass a resistor on your NA tach in order for it to work with the signal outputted by ECU. Quote Link to comment Share on other sites More sharing options...

Just wasn't sure with the pining of tacho signal. Quote Link to comment Share on other sites More sharing options...
