I'm installing a VAFC in my rex w/ a pm6 ECU, and started the install tonight. (I know I know, I'm gonna get a vtec ecu eventually, just didn't have the dough to go obd1 like I want right away...) Everything went fine until I got to the power/ground/rpm signal wires. On the diagram that A'PEXi provides, here, using diagram WH1, my car has a yellow/black power wire where the rpm signal should be, and nothing where it shows there should be a power wire. It was easy enough to figure out which wire had ignition controlled power with a test light, and I can see a brown ground wire, but I have absolutely no idea which one is the rpm... has anyone done this and know what color wire I'm looking for at the ECU?

Also, are the other wire locations correct? There are wires in the other spots, but I certainly don't know that they do what the diagram says...

I could really use some help!
