On the dash where the steering column attaches, right there with the blinker arrows.
That is an indicator to upshift with a manual transmission.
If i am not mistaken, it is the shift indicator light on a manual transmission vehicle
If I'm not mistaken, it appears that your truck is a "manual transmission"? There would be no indicator light - you shift into first gear, and then as you approve about 10 or 15 mph you would shift to second. I recommend the "learning manual transmission for dummies" - actually a very well written instruction book on learning how to shift.
The yellow arrow pointing up is to tell you when it is time to up shift a manual transmission.
If it's the arrow-shaped one in the dashboard of an automatic transmission Jeep, then it's supposed to indicate when you are supposed to up-shift.
With a scan tool or with a battery disconnect.
It is the powertrain/4x4/AWD malfunction indicator. It is the second indicator light covered in your owners manual if you have one.
That light is used on manual transmission equipped vehicles to remind you when to shift to the next gear.That light is used on manual transmission equipped vehicles to remind you when to shift to the next gear.
screwed into the transmission.
Remove the cover to the shifter column. The indicator light will need to be detached from the wiring harness. Reverse the process to install the new light.
Yup, you've got it. I now realize it is the shift indicator. Apparently this is a feature on other vehicles in addition to Wrangler. Thanks to Redbeard, I did some further research and found this on rec.autos.com that confirms his explanation:In article wes...@dsg145.nad.ford.com (Stephen H.

I own a '92 Wrangler and have ignored this indicator light from day one with no apparent reprecussions. Jeep certainly did us a favour by minimizing the annoyance of this light. Specifically, they made it a small outline of an arrow, less than 1" in size, illuminated with white light. This is a vast improvement from the annoying red bar that my '83 Mustang had (suffice it to say that that was disconnected ASAP). Jeep also desiged the indicator such that it will turn off as soon as your speed plateaus, even if you did not upshift. Kudos to Jeep.BTW, I highly recommend the Wrangler.RobAnswerIs that the shift indicator? Many manual transmission vehicles have an indicator that tells you when to shift. The up arrow may be indicating that it's time to shift up one gear.
Your MIL ( malfunction indicator light ) will be lit and a code for your O2 sensor will be logged.
