Okay before you ask questions i have linked some threads for you to read and i have also given you my take on everything....this is a copy of a PM i left someone inquiring.....so enjoy
It has been a long process to get all the leds the way i want (an i still need to do the damn console HVAC fix)!!! As far as difficulty goes, the gauges were the first time i had ever done any soldering before or mods to a car for that matter....so needless to say i followed the DIY thread here very carefully and it took me roughly 3-4 hours to do....but once i did the Hvac, which was pretty hard too, i started feeling a little more comfortable.....then the HU leds are like half the size of the other leds in the gauges and HU and the was extremely hard and that process again took 4 hours nonstop!!! So after all that i recently helped a friend do his gauges and we were done in like 11/2 hours...he kept telling me man this is easy but i had to explain to him What i had GONE THROUGH constantly!!! LOL So all in all its doable but the less experience the longer it will take because you need to take your time!
Anyways here are some threads in case you havent seen them to help you out!
It is not extremely hard but it helps to have some solder experience for the gauges/doors/AC console. Just take you time and follow this DIY
