Well, sometimes we do the unthinkable. I cut one side of my 4-wire connector to the carb off to replace it because it was broken and faulty. I then threw the one side away.... I did tape and write on the wires but it sat and now I can't read it. Does anyone have any idea which 4 wires connect to which? Carb side the connector reads (clockwise) Red; white; black; black. The four unknown wires are Black/thin yellow stripe; Black/thin yellow stripe; Yellow; Black. Do you think the two Black/thin yellow stripe wires matter between them where they go? Thanks in advance!

Welcome to the forum! The black and yellow wires should go to the same place, so it should not matter if they get mixed up. I am not positive, but that is what the wiring diagram shows. It seems that you should attach the black wires from the carburetor to the black/thin yellow line wires because they are the only ones in pairs on each connector. If I remember correctly, the red wire is fatter than the white one, so if either the black or yellow wire is fatter, attach it to that one. The white one is to the fuel cut solenoid, so it should be getting power when the ignition is on. If only one of the unknown wires has power, then it should go to the fuel cut solenoid.

Thanks, the supernerd. Very kind of you to help. I've been driving around with the leads switched (power not going to the fuel cut solenoid).

It was running without power to the fuel cut solenoid? Was it dieseling when you would shut it off?

my wires are sheathed, i had to cut the plug off to run the carb anyway(swapping a 22R into a 20R truck, no provisions for an electric choke or anything). red wire is your choke wire, the black wire coming from the solenoid is +, striped wire from it is -, and the bluish or black wire coming from the little mixture thing is controlled by the emissions computer...i just left it hanging on my truck.

It had been running fine (no dieseling). When I put the power (yellow wire) to the fuel-cut solenoid it clicked like it should, so seems like it was the right move. By the way, the choke works now, too. ...Doh....
Thanks again.

Thanks, Kyle. Seems like we have different carb wirings. You have a nice looking truck! I just redid my 83 in 2004 GM yellow. Looks great (hope no-one swipes it now that it isn't 3/4 rust; that was a LOT of work). It's amazing how once or twice a year someone comes up to the house and wants to buy it (usually someone from Mexico or Guatamala).
