Re: Extended Idle 97-01 Install

So I guess I will switch them and see what happens. I will flip the orange and the black and then try it. The switch works the way it is now so if this does not work I will go back to the way I have it now. Sound ok?
thanks for the help too.

The fog light power goes off when the high beam are on so that's your other problem.
The (run) ign wire should power the High Idle circut not the fog light power.

Re: Extended Idle 97-01 Install

Problem fixed. I had the wires wrong in the plug and I also did connect the Ign (Run) wire. The Ext Idle switch lights up and works great. Thanks again langer1 and JEEPZZ for all your help.

Re: Extended Idle 97-01 Install

That's looks great.

I have grounded the same wire, but I use a ghetto toggle up on the black spot to the right of the intrument cluser. It's right under the ghetto toggle for the aux fan, and above the ghetto red momentary switch for the air horn.

That's great! Does your illumination still work correctly too?
Looks like I'll have to go and reroute mine.

Re: Extended Idle 97-01 Install

alright... i know this says 97-01 install, but I think this would be the best place to ask this. On PCM 12 on the 1996 XJ the wire run through is a dark blue wire with an orange stripe, but it does the same thing supposedly (according to other threads it should be that color even and it is afterall pcm12).

So i disconnected my battery, disconnected the large harness and spliced into the blue and orange PCM12 wire. I extended the wire out (good connection I am sure of...) reattached the harness, the battery and started her up. then i grounded the wire... nothing. tried grounding and then starting... regular idle rpm. i disconnected the battery etc and redid the connection and tried everything again... No results again.

the only result i did notice is that now my check engine light is on - Code 23. Code 23 is the intake manifold temperature sensor giving too much voltage. I think this may be just becuase i moved the iac sensor to the air box (a long time ago), and I've seen this code show up before and go away by itself when i had originally moved the sensor.

I have no clue what I did wrong, but im not sure what else i can do now - other then ask you guys for some help. i sure could use it.

Re: Extended Idle 97-01 Install

I don't know if you have the correct wire but it needs 12+ not ground for high idle.
The ground on the switch is only for the light.
Find Power Steerling sens grounding that wire should give you high idle.
Just be carefull if you get the wrong wire you will blow the ECU.
The wire should be DK Blu-Wht or Violet.

Re: Extended Idle 97-01 Install

well, i misread earlier then, i was under the impression the ground was what needed to complete the curcuit. i attempted connecting the wire to the battery 12v+ and still got no response. still have code 23 and the CEL. dang... thx for filling me in on the positive though. dont know what to do about this now...

That was for the 2000 yours is totaly different.
Like I said it looks like like your can ground the PS SW input on yours.

Re: Extended Idle 97-01 Install

well... from looks of this post it should be the same except for the dashboard pieces. should be the blue-orange wire in pcm 12 for my 96, and again "should" serve the same purpose.

EXTENDED IDLE SWITCH TEST
OPTIONAL POLICE PACKAGE ONLY
The extended idle switch is used to raise engine idle speed to approximately 1000 rpm when the auto shifter is in either Park or Neutral position. A rocker-type switch (extended idle switch) is mounted to instrument panel. This switch is available only with 4.0L engine when supplied with optional police package.

The extended idle switch will control a ground circuit going to the powertrain control module (PCM) When a ground signal (through the switch) has been received at pin/cavity A-12 (circuit K78) of the PCM, engine idle speed will increase.


For 1984-1992 I6 XJs and all I4 XJs:
Not an option in computer pin-out.

For 1993-1995 I6 XJs:
PCM Pin # 10, Purple, [60-pin connector] (Switch On: 1V, Off:12V)

For 1996 I6 XJs:
PCM Pin # 12, dark blue/orange, [Black "A" 32-pin connector] (Switch On: 1V, Off:12V)

For 1997-2000 I6 XJs:
PCM Pin # 12, gray, [Black "A" 32-pin connector] (Switch On: 1V, Off:12V)



Switch location for 97+ (optional 4 opening switch bezel)
