not a big update, installed a cheap tach lastnight, took all of 10 minutes
one thing I hate about auxillary light switches in the dash is that they are usually hard to reach. say you have them on, here comes an on coming car, trying to reach the switch before you blind them. I had the idea to do this in my 4runner but since I got rid of it and will be putting the LED light bar on the K5, here is what I did with a low profile lighted rocker switch.
now with my arm on the arm rest it is within finger reach.
