I need help. I purchased the Rough Country GM Speedometer Calibrator (17-18 2500 / 3500 Diesel Models) Here: because I needed to recalibrate my speedo because of larger tires. The directions are not very clear. Here: https://www.roughcountry.com/speedometer-calibrator-90005a.html?find=2018-chevy-silverado-2500-hd-4wd-283362 Here is the instruction sheet: Inline Speedometer Calibration Kit This installation manual shows an example installation on a 2017 Chevrolet Colorado. The installation may vary for your vehicle, so it may be necessary to consult a Chevrolet service manual for specific instructions for your year model. Be advised: These instructions may not include specifics for all vehicle configurations. INSTALLATION INSTRUCTIONS 1. Connect the Inline Speedometer Module to your PC with the supplied USB cable and configure it to your vehicle. Once configuration is complete, connect the module to the harness. 2. To remove the Lower Kick Panel, first remove the (2) 7mm screws at the bottom 3. Pull back on the Left and Right side of the Kick Panel at the top to release it. There is one connector for the headlight switch on the left. *NOTE* The hood release may come loose from the panel, if so, wait until the panel is re attached to install it. It clips in place starting at the front. 4. Depress tab on headlight switch connector and pull back to disconnect. 5. Look to the left of the steering column and you will see a module with 2 connectors. We will remove the black one by pulling the red locking tab back with a pick, small screwdriver or finger. Depress the tab in the middle and pull backwards to remove. 6. Insert the male portion of the Speedometer Calibrator harness into the female end of the vehicle's harness. Make sure to align the connectors so that the locking tabs are on the same side. Run a zip-tie through the tabs to secure the connectors. 7. Connect the female end of the Speedometer Calibrator harness into the vehicle's module. 8. Tuck the harness up in front of the module away from harm’s way. 9. Start the vehicle and check for any warning signs or messages. 10. Test drive vehicle to ensure proper speedometer function. The fact that the instructions are for a 2017 Chevrolet Colorado don’t really help much either. Anyway, I look under the dash near the steering column and there are 6 different plugs. I don’t know which module I’m supposed to disconnect so I can connect the Speedometer Calibrator harness. I called Rough Country for help but the guy was absolutely no help what so ever. It says it may be necessary to consult a Chevrolet service manual but I don’t own one. I can take some pictures of what's under there next to the steering column if it will help. Can anyone help me find out the correct module to disconnect and reconnect to. I’m at a complete loss. Any help would be greatly appreciated.
I am going to get a tuner/programmer instead of the "Yellow Box" which BTW is made in Australia. I guess that have a distributer somewhere in the US but I decided to take your advise and buy a programmer instead. Thanks for the advise.
Can anyone tell me where the speedometer sensor is on a 2018 Silverado Duramax w/Allison tranny. I need to recalibrate the speedo because I installed larger tires and my speedo is way off. I'm thinking about using a "Yellow Box" to recalibrate the speedometer but I'm not sure exactly where the sensor plug is. It's supposed to be on the side of the transmission but I don't want to disconnect anything until I'm sure of what I'm doing. Any help would be appreciated.
So, I decided to remove the Westin bull bar and install a Westin Grill Guard. I removed the front parking sensors that I used the sensor re-locating kit to move the sensors to the bull bar. The sensors worked perfectly fine. Then I installed them on the grill guard and thought all was fine. When the truck in running in park the sensor lite on the dashboard is lite, but as soon as I take it out of park the light goes out and the sensors don’t work. I don’t know what I did wrong. I didn’t disconnect any wiring except the wiring to the sensors themselves so I could get them out of the plastic clip that holds them in place and all I had to do is snap the connector wires together and push the sensors into the holder then into the locator piece. See https://www.westinautomotive.com/sensor-relocator/2018/chevrolet/silverado-2500-hd So, I don’t have a clue what I did but I’ve taken them apart and put them back together at least 6 times hoping that make them work, but no luck. So I've got no parking sensors, front or rear. I don’t expect anyone to give me a remedy to this problem but just wanted to let anyone thinking about doing this to beware. I'll post a new picture soon.
Thanks. I really don't want to lift the truck that much. I have trouble getting in to it now and just thought I could get an additional 1/2" or so with the 5100's. I had a 3" lift on my Ford Powerstroke with 35" Toro's but don't want anything that high. The guy who installed the 2.5" leveling kit said I could put in a lift kit but the truck would prolly ride like crap compared to the way it rides with the Bilsteins. Thanks for your input. I'll live with what I have now.
I had a 2.5" leveling kit installed and the guy used shock extenders with my Bilstein 4600's. The Bilstein's ride much better then the Rancho's that came on the truck but now I wish I would have installed the 5100's. I'm wondering will the 5100's lift the front even more than the 2.5" leveling kit did. I'm thinking about replacing just the front shocks with the 5100's and leaving the 4600's in the rear. Any suggestions would be much appreciated.
I installed the front parking sensors in my Westin bull bar and forgot to post some photos of it. I disconnected the sensors in the bumper but could not get the sensors themselves out so I bought 2 new sensors on E-bay (but they were silver instead of black). Then I drilled two holes in the back of the bull bar and installed the new sensors and used the harness that came with the relocation kit to plug them in. (see photo). I left the sensors in the bumper and if I ever remove the bull bar, I can just plug the sensors back into the harness. What a bitch it was getting my hand in behind the bumper just to disconnect the harness from the sensors. My hands were bleeding because it’s such a tight fit, otherwise you need to remove the bumper completely which is a major job and then you’d need to put something in the holes left in the bumper. So. I’ll live with what I’ve got. I hope these pictures help anyone interested in relocating their front sensors. I'm going to try and send some pics but don't know how to make them smaller so I might need to send them separately.
The relocation kit is this: Westin 40-0005S Powder Coated Sensor Re-Locator Kit, purchased from Amazon.com. The bull bar I want to install is a Dee Zee Bull Bar Part #: DEZ-DZ507519 and the brackets of the relocator kit mount anywhere on the bar. But, I read somewhere someone didn't use the brackets, only the wiring harness and other parts and drilled a one inch hole in the bar itself and mounted the sensors that way but I don't know how he wired it thru the bull bar. If you're interested check out the kit on Amazon.com and see all the components included in the kit. So, how in the world hoes one get their hand inside the bumper to disconnect the sensors. I'm gonna take off the factory tow hooks (which need to be removed to install the bull bar) to see if I can reach the sensors to disconnect them. BTW, the reason I'm putting on the bull bar is because my truck got hit in a parking lot (hit and run) and dented the bumper (I had 68 miles on it!) It's the LTZ Midnight Edition and the slightest mark will show on the painted bumper. I'm hoping the bull bar will give me a little protection.
I have a 2018 Silverado 2500 HD, LTZ, Duramax, 4X4 crew cab, Midnight Edition, single rear wheel. I want to install a bull bar and need to relocate the forward parking assist sensors. I have this relocation kit: Westin 40-0005S Powder Coated Sensor Re-Locator but don’t know how to remove the sensors in the front bumper. Does anyone know how to do this without removing the bumper completely? I could really use the help.
