Pinout pin name or location in PCM?
 

Ok i'm looking for 1 of 2 things. I did a efan swap from an 05 silverado along with the stock efan wiring harness. I used the pins from 25 and 28 from the rear O2 sensors for the blue and green wires that have to be plugged in to pins 42 and 33. One pin broke so i need a new one. My question is what is the name of those pins so I can go buy them and where would i get them at (radioshack?)Also, if they can only be gotten online are there any other pins for the rear O2 sensors that I can rob from the pcm since they arent being used? I saw each rear O2 sensor has 4 wires so I'm assuming that there are 8 rear O2 sensor pins that will be in the PCM wiring harness? any help would be appreciated as i did a search for pinout on here but nothing suited what I was looking for. Thanks in advance!

You can find whole connectors at Mouser that you can rob pins from if you so desire. There should be a make/model stamped into the connector that you can look up a replacement by.

well i went to radiochack for shits and giggles to see if they had any. i bought a 6 pack of them for like 3 bucks. the look pretty identical only difference i can tell is that the female port (hole) is a lil bigger than the stock pins. i just used a pair of pliers and evenly closed the gap to pretty much the same size as stock. havent put it into the harness yet but from the looks i think it might work. if not ill def check out that Mouser. question, is that something u can only get online or can it be bought in store? i.e. oreillys, advance auto, autozone? thanks

Go to your local "U-Pull" type of salvage yard. There are a zillion different GM cars and trucks that use the same pins.

i didnt even think about that, thats a good idea. if the radioshack ones dont work out ill just use the other pins from the rear O2s since i have a wiring diagram now :)
