Hey guys, looking for a tach wire in a 91 Nissan Sentra. my wiring info says it's either GREEN/ yel, blue/blk at the coil, but there aren't any wires that match at the coil... does anyone have any updated information?

thanks,

hey guys, don't mean to ask so many questions but I can seem to find the ECCS unit?? above it says, "Unit Located Below Center Of Dash Behind Center Console" But I can't seem to find anything that looks like it... anybody have any ideas? is it maybe integrated with anything? or any other places I could possibly grab a tach signal from?

thanks

just to expand on this, It seems there are 2 other places I have come across that I might be able to grab the tach signal from... one is,

Cold Start Wire- BLACK / YELLOW At Ignition Switch Harness,

and possibly the ECU... anyone have the location, and wire colour on the ECU, and if not, do you think I would be able to get a tach signal off the above black / yellow wire from the ignition harness?

thanks again.
