Is this the right wire?

[Twizzler09]

I've been working on an aftermarket Tach install (the factory tach no longer works...and this one was only 30 bucks, couldnt help myself, lol).

Well, I've got it all wired up and the tach has power, and it lights up like it should, but I'm not getting an RPM signal from it. The Tach input should be from a Tan/Yellow wire off the PCM, pin 48 if I'm not mistaken. I spliced it into the only Tan/Yellow wire I saw, but no worky. Did I get the right wire? Or am I blind and completely missed it?

This is the wire I spliced into:

This is the giant mess of wires I have to look through:

Lastly, the chart I used for identification:

The PCM is located under the hood. Your info is missing something, the wire is in position 48 (as stated) of the 104 pin connector(which they should have added). Tan/Yellow is the right color. Hope this helps
