ggcnash Posted October 9, 2015 Share Posted October 9, 2015 Brother, bought this service jeep from uncle who is fire chief in town. Uncle says it was ordered with center console option and column shift. The back side has the same tabs as on the back of regular shift plate, but it is made of metal. Same plate I have for mine pulled from JY unfortunately same holes in mine, uncle says his came from a ram mount (CB,laptop,radio) Link to comment Share on other sites More sharing options...
ggcnash Posted October 9, 2015 Author Share Posted October 9, 2015 Now if Chrysler didn't offer this part (block off plate)who did? As stated before extremely precise to be homemade plus the fact that I have the exact one from a totally unrelated service jeep with same options pulled from JY.

teamsmith Posted October 9, 2015 Share Posted October 9, 2015 What does the extended Idle button do? Link to comment Share on other sites More sharing options...
ggcnash Posted October 9, 2015 Author Share Posted October 9, 2015 For when parked runs idle up to 1200 so wouldn't over heat. Link to comment Share on other sites More sharing options...
ggcnash Posted October 9, 2015 Author Share Posted October 9, 2015 Only available on HO service models I believe. Link to comment Share on other sites More sharing options...
Lee21490 Posted October 9, 2015 Share Posted October 9, 2015 For when parked runs idle up to 1200 so wouldn't over heat. That's pretty cool. I googled it real quick, Looks like you can add in that switch to pretty much any XJ, Just have to jumper into the ECU. I may end up doing that, Since i convereted my AC into a air compressor, The extra RPM @ idle would be great for extra air flow. Link to comment Share on other sites More sharing options...

Yea, unfortunately only 92 to 96 tried on 91 pin outs aren't there Link to comment Share on other sites More sharing options...
ggcnash Posted October 9, 2015 Author Share Posted October 9, 2015 I will rephrase that it has been done on a 91 with extra wiring just not as simple. Link to comment Share on other sites More sharing options...

It for sure isn't in the parts manuals throughout the XJ/MJ years. Link to comment Share on other sites More sharing options...
mikekaz1 Posted October 10, 2015 Share Posted October 10, 2015 And I swore I've seen it all..... yet you add even another thing to the list! I've never seen an idle up switch! I'd love to have that. .... ugh now to scour the inter webs on doing it to a 1991 Link to comment Share on other sites More sharing options...
mikekaz1 Posted October 10, 2015 Share Posted October 10, 2015 I will rephrase that it has been done on a 91 with extra wiring just not as simple. I've literally looked for 2hrs. For 1991. Can't find any confirmed wiring. Please enlighten me with information please Link to comment Share on other sites More sharing options...
HOrnbrod Posted October 10, 2015 Share Posted October 10, 2015 http://www.naxja.org/forum/showthread.php?t=35197&highlight=extended+idle http://www.naxja.org/forum/showthread.php?t=77285 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) I've looked into this a bit in the past. To elaborate for the 91-92 ECUs, there is no pin 10 appearance on the 60-pin ECU connector on these models. Applying a ground signal to this pin from the "Extended Idle" dash switch is what will cause the increased idle. Since there is no pin 10 on the ECU, you will have to modify the motherboard in the ECU to extend pin 10 either to the existing 60-pin connector, or run a wire out externally so you can connect the ground signal applied by the extended idle dash switch. Was not worth the effort for me. Link to comment Share on other sites More sharing options...
