ok on the DX harness theres this connector with a orange wire and a black wire with a yellow stripe. i remember your suppose to cut both of the and tape one of them off as a "hot ignition" wire and where does the other wire go? THANK YOU

 

ANYONE?

 

uhhh pics could help

 

sorry no pics for now but its has a white connector that faded. please help

 

remove that plug from the harness, tandem valve is a dx only item

 

Whats a tandem valve?

 

Straight from a civic shop manual:
The tandem valve is employed to improve atomization of fuel which is injected by the main fuel injector in response to various operating conditions.
When the tandem valve control solenoid valve is activated, venturi vacuum is applied on the tandem valve control diaphragm and the tandem valve is opened in response to the venturi vacuum which represents the air flow rate through the venturi. Therefore good atomization of the injected fuel is provided regardless of air flow rate.

So basically it increases fuel economy, sacrificing some airflow. Fortunately it doesnt exist on an MPFI intake, so just do what droppedcrxsi said and cut it off. However, if your intake has an FICV, you can use those wires to power it, save yourself a little bit of wiring.

Good luck

 

your suppose to tape one of them off as "hot ignition" when the key is in and turned which one do i tape off?

 

if you have a multi meter you could just test it with that

why not just tape both?
usually blk/yel is a hot but maybe someone can verfiy this

 

black/yellow is "hot" with ignition on

THANK YOU GUYS ALL. I WILL MAKE ANOTHER THREAD WITH PICS OF MY PROGRESS. THANK YOU SO MUCH

 

what the hell are you talking about? i did this conversion on my dx just the manifold, and i have no clue what your talking about. if its the extra plug left over iv only read that you just leave it unpluged seeing as theres no where to plug it in to.
