mixture control solenoid

[megaladon6]

i just found out that i have the wrong m/c solenoid in my carb. does anyone know if i can just change the harness-side plug and go? i have the single plunger/black connector carb, i am supposed to have the double plunger blue connector. or, can i just leave it disconnected? this is for a 383ci in an 87 monte ss.

That depends. Are you still using the PCM for engine and emissions control?

yep, stock ecm. i will be getting a new prom of course but i want to get it up and running first.

What was the engine harness in originally? The '87 SS harness should have the blue plug already. If it's not the '87 SS harness I have to ask what car the ECM is out of?

What I'm getting at is how do you know you have the wrong parts installed now?

 

[megaladon6]

it's the original harness, not the original carb or engine. the harness is for the blue m/c. the carb has the black connector.

Can you get your hands on an '87 CCC carb and swap it out? MonteCarloSS.com has a great article in the technical section on opening up these carbs and adjusting them for performance.

I would think that this would be your best option to avoid butchering the harness or confusing the ECM.

Come to think of it, you'll also need to keep the CCC distributor and get the proper knock sensor for the 383 as well.
