Another hack and slash job.
It is scary that there are people out ther that actually do that sort of thing to a vehicle.
Thanks for posting the pictures.
That harness is the half that runs to the ECM.
The other half normally contains the idle cut-off solenoid and a couple other things on the carburetor, which I don't recall right now.
A separate, two wire connector controls the mixture control solenoid on the carburetor, which since I didn't see the harness connector, was probably cut off the carb.
Bottom lline, you have to make a decision here.
1. If your state has mandated emissions testing, you may have compliance issues.
2. You can take the vehicle back to stock. . .and that is going to cost time and money. Personally, the best mileage you are going to get with a stock setup when the systems work is better than what you will get with a Weber. . .but the complexity to get back to stock may not be worth the trouble to you.
3. If the vehicle was not sold with a passing emission compliance certificate, you have grounds for a recission of the sale, if the state requires a passing e-test prior to sale or transfer.
4. The stock carb setup is set up to run rich in failure mode, so a Weber by default will do better than a broken stock stetup like what you have.
