Regeared.. Now to deal with the speedo?

While I would trust anything Josh provides through Skinny Pedal Products, I don't have any experience with the "yellow box." I have had the Superlift TrueSpeed installed for several years now. It was extremely easy to install and has performed flawlessly, requiring no adjustment or attention.

Another option, albeit a more expensive one at $160, is the plug-n-play HealTech Speedohealer from the motorcycle world.

I installed the Yellow Box a couple of months ago. It was very easy to install, very easy to set and so far has worked flawlessly. Give Josh a call. I think he has made the install even easier by making it a plug and play. When I bought mine it was all solder connections.

My Yellow Bocx work grat and was simple to set up. A GPS make calibration a snap.

I left it alone for years when I was running 35s with 4.10s ... I've left it alone since doing 4.88s. Basically, you'll soon realize speedo is fairly useless on a lifted jeep. The only reason I'd ever look at a speedo is to not get a speeding ticket and I am almost never in danger of that in the jeep (except in a school zone perhaps)

X100 on the Yellow box, twenty minute install & works great! I used the GPS to calibrate it and verified it with the mile markers on the freeway, dead on. Can't beat it for the money either.

It's not on mine. I depend on an accurate speedo to keep from getting tickets. Yes, I have a heavy foot, even in a lifted Jeep.

I went with the Yellow Box. Simple install, and works great. If you ever change gears or tire size, it's a snap to recalibrate.

1 for superlift, 3 for yellowbox.. I'm rocking Skinny's in cab controller and the H4 harness.. Hmmm.. Thanks I'll get it ordered soon!

Nah, really 4 for Yellowbox. I was just reporting how the Superlift unit installed and works. I'd rather see you support Josh in a heartbeat, any day of the week.

And if you search enough you'll see that a few have had issues with the Superlift unit. (myself included) I haven't seen any complaints so far about the unit that Josh sells.

FedEx delivered a Yellow Box last week from Skinny Pedal - now I need to make some time to install it. It is not plug and play - I'll have to cut/solder into the speedo sender wiring. Looking forward to having a reasonably accurate speedo.

btw did some looking with my modis (fancy scan tool form snap-on) and didnt see a place i could manipulate the calibration for tire size. Usually that stuff is in the ABS portion and being most jeeps dont seem to have ABS i cant seem to find anything to adjust. If anyone is local to me Long Island, NY and has ABS in their jeep we could meet up and i could check that out.

Does the Yellow box come with instructions? Has anyone done a nice write up on the wire colors and how to test if you have the right wires? I don't have a FSM for my jeep yet, so where and what color are the wires that I am looking for?

Thanks in advance.

Yes, it comes with instructions. Since the colors and location on the PCM change for different years, you are gonna have to crawl under your rig and check out the colors coming from the sensor at the transfer case. Your PCM is on the passenger side firewall. It will have 3 large bundles of wires with 3 plugs going into it. While I cannot recall the colors, I can save you a little time and tell you that the '03 wires are in the middle bundle. I tapped in there and placed my yellr box behind the glove box.

x1000 on ease of calibration when using a GPS receiver.

Just dropped the dime on the yellow box.. Hoping it comes quick! Drove the heep home from the shop today, it's 11 mph off and man has some pep again!

You really will like the unit. If, you choose the "high and dry" mounting location, behind the glove box then, you will need to extend some wires to tap into the PCM. Don't try scotchloks if, you do not know how to solder. I was solder challenged for decades but, a search on YouTube house cured me.

Just hoping it shows up before Thursday, so I can get it installed on my day off.
