I have almost everything figured out on my wiring harness except two plugs. Below are pictures and a discription of what I need to do.


First is a picture of my O2 wiring as it breaks out of the harness by the starter solenoid on the fender. The one on the right is currently on the truck from the 1995 F250 I got the motor from. The one on the left is what broke out of my 1994 F150 300-6. My harness down to the O2 sensor and my new sensor all match the one on the left. Is there a way to repin the one on the right to the one on the left? If not any ideas on what wire does what before I try splicing? They look very simular but when you look closely they are keyed 180 degrees out from one another.







Same thing with the image below. The 8 pin connector is from the 95 harness and the 4 pin is from the 94. I need to lose the 8 and make it the 4 but need to know for sure the pin outs.

 

Nobody huh? I think I've reached the end of the internet and it may be time to turn back through my Google portal then.

 

I believe that the pins will interchange, so you can just swap one connector for the other. Pull the red pin-lock from the center of each connector, then use a small glasses screwdriver to push the tabs towards the center of the connector to disengage the pins and pull the wire and pin out the back of the connector.

As for what wire does what, I have no idea.

 

Now if I can track down the wire colors to the pin positions. I could be all wrong here too. Iy is possible the 95 F250 O2 sensor comes out somewhere else and that connector is something else.

Does anyone else have a 95 F250 eith a 351 that can tell me where the O2 connector breaks out of the engine bay wiring harness?

 

might be tedious but you could try just tracing the outs up using the connectivity setting on a volt meter or just following it by hand.
course i have now idea how that harness is set up but that's what i would try if you can't find the pin diagram or someone who can tell you which pins are which

 

i would get a diagram from each vehicle and cross reference the wires,and swap the hardshell,they can be removed from the connector and put em where you need um.

 

Repinning is easy. See the red "divider" inside of the plugs? Use some slender, long needle nose pliers and pull the divider out, then you can pull out each wire from the back side of the connector.
