Im wiring up my ex6, I dont need the idle speed motor control, 2 of the wires on the cas/reluctor/whatever and a few other assorted ground and power wires.

what is the RIGHT way to handle extra wires
just cut them out? bundle them up in case someday i need them?

 

Do you mean like you're using the stock engine harness? Or that you simply wont use an idle valve? And to which CAS wires are you refering 2? there are 4 and you use them both.

 

I guess it depends on the installer?
If the Haltech is never going to move, you can either cut them short or just de-pin the harness to remove the excess wires.

For customers, if there is enough space, I just bundle them and tie them out of the way.
In case the Haltech does get moved, the extra wires just might come in handy.
I cap all the bare wire ends to prevent possibiliy of shorts.

Yeah, i agree with Ted, i usually leave the extra wires bundled up, you never know when you might need them later on, or used them as other options.

 

I just de-pinned from the ecu connector, Im going to save the wire in case I need it later.


do you guys know by chance what they grey wire in the trailing coil connector is for?

there are 2 tan wires for power
white and pink go to the haltch
yellow is tach signal
I cant figure what grey is.

 

There's a "feedback" wire that goes back to the ECU to tell it that the igniter is working, you dont connect that, im not sure if thats the grey color, i always leave the stock connector wires in there after the connector so i have something to disconnect if later the car needs to be taken apart.

But thats probably what it is.

 

I used the stock coil connectors to, I really hate to permnantly wire anything.
Im running the power wires seperate from the signal wires that go to the haltech, 1 10gage wire for each coil into the car to a 30amp relay and a switch
