Help finding RPM Signal Wire

[Katapl]

I've got an S13 with a redtop in it. I'm trying to hookup my timer and can't find the RPM Signal Wire. I hear it's brown w/ red stripes on an S14. I checked the ECU pins (according to the HKS diagram) and all I found was an orange wire in one location, and a white wire in the other location. I wasn't even sure which side of the ECU, so hell, I checked both top and bottom.

Any ideas on which color this is? Or any place besides the ECU?

EDIT: I just decided to route it in where PLX said to on the ECU. I then hooked everything back up and started it. I couldn't figure out the modes and all, but oh well. I had it on some RPM mode and it read 330 or something during idle. I reved it a bit and the RPM on the timer shot up. I'm not sure exactly how to use the timer yet, but at least I know it can be set to auto now. I'll get it figured out tomorrow.

Hell ya.
