Could somone take the time to walk me through the process of locating the ignition timing adjustment connector, and how to use it? The only connector I see is connected to the 02 sensor...then there are two on the firewall that I'm certain are for a tachometer. The area the manual indicates it should be points to the o2 sensor connection on the wheel well.
I understand the importance of this procedure, but I am not sure how to carry it out. I'm avoiding driving the truck until the timing is right. I keep searching this forum but it's difficult to find specific threads, and the search feature isn't helping much.
This is the only photo I have that shows the connection I see, it joins with the o2 sensor (red arrow).

EDIT: That is indeed the right location. Below, I hold the cap to the connector, just near the connector itself.
