Im actually looking to do that same thing as he did (using his idea) but after my EFI swap this past weekend I dont have enough length on one of the connectors to get it up in the glove box. All I need are the yellow plugs that go into the ECU and was going to take apart a junk ECU to make the other end of the extension. Let me know if you have the plugs (which you probably dont being its a Carb'd harness)
Thanks!
