would like to know what they do when i connect them it causes the engine to stall and stutter and it spit out white smoke from the intake.

 

But when there not connected the cars fine

 

the first one is the connector that when disconnected puts the distributor into "base timing mode" . I don't know what the second one is because my car doesn't have that connector (something else different between the 6 and the 8 cyl cars) .

 

With the first on disconnected, you need to reset your base timing. Then, for the engine to run right, you need to hook it back up.... If that causes the engine to run bad, then you have a problem somewhere.

What is the second one for? Can you tell where it goes?

 

No I haven't followed it back i will today when i get home.

 

the second one looks like it's got something to do with the HVAC system since it goes thru the firewall above the heater box.
high speed wiring for the fan, perhaps?

 

The first one is called the (EST) wire/connection.= Electronic Spark Timing.


This is how its used to set your base timing to the stock configuration.
This needs to be done.


(Start car and idle until the car is at operating temp. Disconnect the EST wire, adjust timing, reconnect EST wire. Shut off car .)


Just leave yours unhooked in the beginning and set the timing then hook it up as described.


If your still having problems than at least you know the timing is set correctly.


There is another procedure that is also important called "setting minimum idle speed"


The timing has to be set to the stock setting before you can do it.

 

Thanks for the help

 

If the engine light comes on after setting the timing/messing with the EST wire just unhook the battery for a few minutes.


Also , take it easy on the car for the first 20 miles or so. Drive normally , don't "hot rod" it. That will give the ECM time to relearn the new settings.

 

The Black square when hooked up my car wont start. so i dont think it goes to HVAC
