85 cutlass...couple questions.. disconnected wires? vaccum?

[shorty]

Whats up guys I just got myself a 85 cutlass supreme (V6 boo) anyway.. I have some minor knowlege about cars, but no specific knowledge on these vechicles... I am going through some trouble passing smog here in CA and am trying to make sure that this vaccum is in proper order... and also I am wondering what these empty plugs go to?!?

What are these two plugs?

-------------------

Look at both pics please to see what vaccum line I am talking about, I highlighed it in RED. 1st pic is comming from the passenger side, 2nd behind the carb.

The splitter had some electrical tape and it looked like the vaccum didnt fit over the valve properly, i dont know if its even supposed to be hooked up like that...


------------------

Someone told me this is a diagnostic plug? is that true?

This leads me to my next question, I am throwing a code (check engine light), in my other cars I have been able to use a jumper pin to read what code the ecu is throwing, but I am not sure how to do so....


Thanks in advance! I am trying to search around the forums and learn as much as I can.

i was thinking that is a diagnostic plug. as far as the vac i'm not to sure. you need to find a diagram for that year/make car

I have 5 of these cars, 2 of them are parts cars with v6 in them and 2 are v8's. and one is for dirt track. I will look at them this weekend and see how they are hooked up. the back one against the firewall, I think, is sapposed to be hooked to a check valve and goes runs to the heater control. Hard to tell from the pic. if it is, it will go into a harness near the passenger side fender at the heater fan.
feel free to shoot me an e-mail.

The green single wire connector is a diagnostic plug. You can connect a normal dwell meter to the plug and read the duty cycle of the mixture control solenoid in the carb. This lets you adjust the idle mixture to spec. You jumper the two top RH terminals in the ALDL connector under the dash with the key on but the engine off. The check engine light should flash a sort of morse code. It will always flash a Code 12 to start - flash (pause) flash flash - then repeat this code two more times. If there are any additional stored codes, these will flash in sequence in numerical order. A Code 42 would be - flash flash flash flash (pause) flash flash. Each stored code is signaled three times. When all are complete, the Code 12 will flash again and the sequence will repeat.

The 2nd and 3rd pics where i drew RED on the vaccum are the same line, thats why im trying to see if its in the correct position.

in the 2nd pic you can see a different vaccum a GRAY one, that i found hanging, and i plugged into the check valve for the heater, was that the right one? You can see its kinda stretched, but i figured it was the right position for it...... is it the red? what is the giant black circular canister that it is plugged into?

thanks for the help guys! Im trying to pass smog, and I had the previous' owners mechanic turn the carb to run reallly lean, i passed everything but the NOx... tryin to tune this thing properly so it will run with the proper mixture w/o tossing a bunch of money into it....

ya i thought thats how i check the ecu, i just couldnt find the plug under the dash.. all i could find was a interior bulb wire.. may have to peel the carpet back a lil i guess....



curious question...
Would my car be a good canidate for a swap?

The ones you have red lines on are for the A/C system vent motors, and the cylindrical thing is a vacuum accumulator. It has no bearing on emissions except if there is a leak. Disconnect it, and all that will work on the A/C is the defroster, as that is the default setting for safety reasons.

The ALDL plug (diagnostic) should be under the dash, next to the ash tray. They bolt to the same bracket.

As far as swaps go, any car is a good candidate, but it is not always practical for the owner. Doing a swap is one thing. Doing a swap with the intention of passing a smog test is another thing entirely. If you read my sticky in the engine swap forum, you will see the entire list of parts needed to swap from a Buick V6 to a Chevy V8 with the proper smog controls in place. Same car as yours right down to the year. Fortunately for me, they stopped checking here in Florida right around the time I did the swap, so it was unnecessary. I did keep all of the parts though just in case I ever have to .

any idea what the big black connector and also the gray 2 wire plug does/ goes to?

 

[85 Cutlass Brougham]

I will venture a guess that the gray 2 wire connector is a weatherpack connector that should go to the diverter valve on the smog pump, or wherever it is located. IIRC, it's in the right spot. I would see if it plugs in to the black connector. It's been about 12 years since I had the V6 in my Cutlass, so I am a bit rusty on what goes where.
