wire harness after single?

thanks

how many of them do you chop off, and does it throw any codes?

Chop them off, but be sure that the Idle solenoid still has power. This mod might require reconnecting about 3 or 4 black w/white stripe wires back together. They are all located together where the solenoid rack wires branch off the main engine harness.

What would be the symptom of cutting that

All the 3/4 wires are from the same solenoid? and you just splice them all together?

No they are the +12V supply for all the solenoids. Basically if you cut it then your Idle air control valve won't operate at all so idle will be erretic. More than likely an unassuming person would change the bleed screw to lower the idle speed and then it would have to be adjusted with the weather. Basically the supply branches out at the root of the solenoid rack so that is why there is 3 or 4 different b/w wires. Just connect them all. You only need 2, but save the trouble of testing them all and solder them all.

I'm pretty sure it's the solenoid that bolts to the bottom of the UIM right behind the throttle body. Most people that go single elliminate it (I don't think the Haltech can even control it), & most block off kits come with block offs for it.

I don't have it, my idle is a little odd as I sometimes have to blip the throttle to get it to settle back down to 800 but I live with it & don't make adjustments from cool to warm temperatures.

i have heard people say you need to with the PFC.... but you realy dont have to. nothing will happen if you dont. no resistors needed, and yes Nick just chop them all the hell off of there.

Or you could do what KD did to Zoomzoom's car and solder the IAC wire onto one of the wires coming off of the secondary injectors

The IAC sits on the UIM right next to the TPS. The ECU controls the amount of air that goes past the TB by opening/closing of the IAC. You might very well have idle problems if you don't run an IAC and your tuning is off. We have discussed the problems in the PFC forum in a tuning thread (I think). Eliminating the IAC can be simulated by turning off the idle-ign cntr on the PFC options menu.

So what questions do people have? Mainly I would suggest unwrapping the tape around the harness and look at what wires you are cutting. The black w/ white or black w/ yellow are +12V supplies.
