i use the truck to pull the boat and daily driver, so it only sees 87 octane fuel , to take full advantage of a tune you have to run 93 ,i just want to recalibrate the speedo the cheapest way possible , we have a gov at 98mph in my case i cant pass 80mph on the highway , need to fix this ASAP

no , its off because the gear change , and bigger tires

what are you guys doing once you install gears and 35 tires to recalibrate the speedometer ? my truck originally came with 3:23 gears , so i upgraded to 4:10 and 35 tires speedo is way off 98mph on the dash 80mph on the phones GPS dealer or programmer ? whats the best option ? cheapest option

well i got it to work correctly , up down and side to side and brown with orange stripe is the heating element + now where do the other 3 go ? or what did they do on the DL8 ? i assume black goes with black ? and the brown goes with the grey i have left in the middle row ? of the mirror harness on the truck harness i have left black with blue line white with green line blue with grey line

i broke the pink wire , rookie mistake , was going to re-pin the mirror harness and then saw everyone re-pining the truck harness , didn't know you had to lift the white tab on the plug , was doing it the old school way lifting the plastic tab next to the pin with a small tiny flat screw driver pulled to hard on the cable , no big deal , easy fix on the mirror harness passenger side pink = glass turn signal blue = side cargo lamp red = running light front of mirror black i assume is the heated mirror or ground on the truck harness passenger side black i assume is heated or ground from what i read green with black line = mirror right white wire = left yellow with brown line = UP

DL8 , I try sending phill a PM but either hes not accepting any or the system doesn't let me because i'm new these definitely look aftermarket judging by the color of the wires

i'm new to the forums , ive searched all over and cant find what im looking for my truck is a 2015 silverado LT 1500 no idea what mirrors it had on it , someone installed towing mirrors and the functions would not work correctly passenger would only go up and down when using the left to right arrows or vice versa driver only goes up and down the pins are not in the correct place for the towing mirrors truck harness has 9 pins mirrors have 9 pins so i took all the pins out from the factory harness on the truck and started testing with voltmeter but cant get them to work anyone have a color diagram on the factory plug to see what does what ? i just want the mirror to move up and down, and side to side for now ill worry about the other features later on , ive read you have to add 3 wires to the harness or buy PGAMBOA harness
