[QUOTE="2003tahoe, post: 2408, member: 145"] Ok time for the tiedest part of this mod ,soldering, with soldering if you have it to hot you can get the contact to come undone from the board which is bad news:mad:, and if you have it to cool you can have the risk of burning something while your waiting for the solder to melt. The trick is to have an adjustable soldering gun so you can slowly turn it up by notches till your solder will just barely melt which is what I did this time, the last time, with all the door switches and all the controls which I will show y'all (sorry from Texas) how to do later on as I have time to take all the stuff back apart. If you don't want to spend the money for the adjustable one go down to autozone and get the pen style for a third of the price ( I use this one to stipple my 42 rnd ar-15 mags ) its good for the price but if you are going to do the entire truck might as well just get the adjustable one like i got its a cheap Weller, it is also a great gun to start off with since you can do multiple things with it not just the board in your truck, its the same one i started off with back in 2008. well enough gun talk and back to the reason why you'r here. Well to start off you will need to know what is power and what is ground on the leds that we are modifying. Below is the drawing i made of the power and ground ( I know not a good drawer that's why i'm trying to be a cop ) [ATTACH]77.vB[/ATTACH] [ATTACH]76.vB[/ATTACH] Ok so now the original bulbs have a square base ( sorry no pics again since i did this around 2012) if I remember right the solder points are at opposite cornors of the base and will be a tight fit to get the soldering gun in at some points. Here is the old 5mm round tops that are not good for this application will show later on. One more thing the brown that you see is rosin from the solder not a burn spot. [ATTACH]80.vB[/ATTACH] Here are the better 3mm flat top leds to use. [ATTACH]79.vB[/ATTACH] you will need to do the same for all 9 bulb locations, if you get lost on which ones show in the gauges put the white cover back on and write down the locations of them. Ok now that those leds are replaced and you want to replace the stepper motors you will need to get them out [ATTACH]78.vB[/ATTACH] Note: make sure you dont shoot your finger off while grabbing them, 40 S&W can hurt pretty darn bad. :rolleyes: Now that you have the stepper motors out you will need to make sure you don't harm the fresh leds, i just held the board in my hand at the corners so i didnt touch and soldering points. The motors are held on by 2 plastic prongs and 4 solder points which is were the solder sucker comes in handy instead of heating up the points and pushing which can also disconnect the solder points from the board which again is a bad thing. Just make sure all the solder is off the motor contacts so you can safely push the motor out of the board. Install of the new motors is the complete reverse of the removal. [/QUOTE]
