Another wiring question
This should be an easy one I hope, I'm trying to get a signal to my tachometer and I have read on here about a few different places to get my signal from. I started with the Y/L wire off the trailing coil and got nothing, then I tried pin 1M off the ecu (I read that one somewhere on here bu they seemed unsure about it) and that didn't work. I only have a few wires from the front harness hooked up (just the ones that go to the coils, main relay, and battery) so that might be why some of these aren't working properly. I have also read I can hook it up to the black wire off the leading coil; is that correct? This is for a dune buggy and aftermarket tachometer fyi.

I forgot to mention that I have already checked for spark on the trailing coils, and I am getting spark consistently. I am using stock S4/5 coils and a S5 NA ecu (I can't remember the # but it's either N370 or N350, from a 1991 NA).

Are you saying that if I'm not using that part of the harness (which I'm not because all I had was the connector at the ecu with a few inches of wire to start and I wired it directly to the coils and injectors) then there is nowhere to get a signal for my tachometer? What about on the coils where the wires connect to them (there are 2 "studs" with nuts on them under a cover)?

This is in a dune buggy. I don't have a gauge cluster, just an autometer 4" tachometer, oil pressure, and temperature gauges. I already have the other 2 working I just need to get my tach to work as well.
