Your tach signal comes from the main harness not the lower harness. It should be F3 plug in S14 or if you have S13, it's that dash cluster plug.

I don't think you have to do any modifications to the lower harness. I remember for my SR swap, I didnt even touch the lower trans harness.

If the motor is a S13 Redtop or blacktop in a S14 you will need to replace the speend sensor from your S14 transmission into the SR transmission. If not the gauge cluster will read x2 the speed your really going.
