The wire that comes out of the harness is usually red for the choke but if you cut the harness tape it's just spliced into the ignition feed wire in the harness before the ballast resistor. No biggie. Sometimes a bad choke pulling too much voltage can cause the feed to go down so just check the voltage to the ignition and choke when you get it running.

Wait! ............don't mess with the harness.
The new DUI uses switched ignition - you can share that wire source. Also, you should still have your ProTec circuit breaker which is a switched ignition 12v+. That is near the carb and a freely accessible attachment point (no crazy splicing). Terminal 26 on the diagram below.............

It looks like on the diagram it is terminal 41, will either work?

Yes.... but:
26 is the breaker protected side (out).... 41 is from the engine harness unprotected side (in). Use the breaker if you got it........... (plus, there physically should be more room on the 26 terminal, if it was like mine) Put a volt meter on it when the ignition is "ON" to verify. (ground out on nearby relay ground) |

I would not recommend protected side of that 2.5A breaker. That breaker was likely there to protect the (now defunct) Protec computer and/or small gauge wiring that fed it. The wiring in the harness can handle more current, and I would not intentionally limit what is supplied to the DUI. Connect to the unprotected side.

I couldn't find a harness schematic. The PCM Pro Boss GT-40 manual in the reference section has a lot of info in it that may or may not apply to your engine. I would look through it and see if you can identify some of the components/sensors. It looks like there may be a MAP sensor in your picture. Based on what you figure out you could clean up the harness. How did you wire your tach? As far as the choke goes I would wire it as TRbenj mentioned. Before the 12V gets to the key it comes from the 50Amp breaker point 22 on the engine then up to the dash and through the ignition breaker then to the key and back to points 28/41 and 31 so it is protected by two separate breakers. |

So i got the dui all hooked up and timed, runs great
Got all the unnecessary computer and wire harnesses out. Runs great. but after i shut it down it looks like fuel is dripping from the boosters and causing it to flood? When its cold it fires right up. if i start it right away after running it it starts fine. but if i leave it sit for 20 min it floods and is really hard to start. |

Might be time for a carb re-build. You should not have fuel dripping out anywhere.
