104 pin PCM Pin layout

This is for 97 SOHC

Page 23-6 clearly shows pin 46 connected to the air inlet control valve (solenoid). I tried separating the wires in the bundle on the engine side of the main engine harness electrical connector mounted in front of the ignition coil pack and looked for a brown wire. The colors are faded so I may have found one but I'm not sure. If I disconnect that connector will I be able to find pin numbers that correspond to the pin numbers at the PCM connector?

I really appreciate you posting all of the PCM related diagrams. It is a real service to me and other forum members!

The diagram for the connector should match as you are looking at the connector face (after you disconnect it). You should also be able to orient it by looking for the color codes on some of the connections (e.g. Pin 1) and matching it that way.

It is possible that the version of the manual that I have is an early edition and that they may have corrected the manual to show that circuit in the connector in a later version. My manual isn't from "official" sources.

Hello ,
i have 1997 sohc 2wd ...
I am installing a new entrainment center with rear view camera
and i need to find a back up light wire and a park position wire , i been told to do it from the dtr on the transmission and i am wondering if i have access to such wire from the pcm harness ?

Not really, the backup wire does not go back to the PCM - there is a set of 4 wires connecting the PCM and DTR sensor, but there is not a separate park position or backup wire going back to the PCM as near as I can tell.

hi guys.
I am Brazilian and I do not speak English very well.
precise outline of the pcm pin eec v of a 2001 ranger sohc v6 210cv.
do not know if realized, but the third part of the pins on the page that has a think are the v8, which indicate the pins 91-104, lists four lambda sensors and injectors 2,4,6,8.
cnsigo not find this part at the v6 referendum, could someone help me?

Will the 97 wiring diagram work for a 99 sohc? I am doing an engine swap and the new engine has a random wire sticking out about 2 inches from the pcm connection. there is no indication that the wire has been disconnected or taken out of the current wiring harness. I also checked my old wiring harness and there is no blue wire in the same location.

Nevermind my last post. Someone tapped into a wire.
