To anyone who is savvy with wiring on these trucks can help..
I have No issue with my 88 F-250. Keep in mind that I know how to pull codes with a paper clip. Again I'm not having issues but want to find a wire
Back in the day I had the CP 9015 code scanner that crapped out and I just got another one..
I would insert the plug that has three pins.
-Self Test Out
-Fuel Pump
-SIG-RTN
into the scanner AND i remember that I had the wire dongle (SELF-TEST IN)
that would also plug into the scanner. BUT I CAN'T FIND THAT DONGLE!!!!! I don't know if I cut it off OR it just dissapeared.
see pic..
Can anyone tell me where I can find this lost wire and can tell me how to locate it in the harness so I can splice and get back the SELF-TEST IN) so I can use the scanner.
Again, it was there at one time and i'm beating my brains out trying to figure out what happen. I had this wonderful truck since. 1994. Don't know what happend.
