hey buddy. Are you trying to get them blue or still orange?? If you are getting them blue you need ot order the leds fomr RJ as well and sodder them in. after there he is what you need to do:
1st of all you cant jsut stick rj's overtop ur current gauges with blue leds. the stock orange wont let the light through. you need to tkae off the needles and the old gauges. As it is you need to take off the neeldes and gauges to get to the leds to resodder them.
So jsut pop off the neeldes using liek 2 spoons to pop it off, take off face and sodder in ur new blue leds inplace of the old orange ones. Now put RJ's gauges on with ur old gauges off.
For the neeldes, if you want red needles do liek carbonblue said with putting 1 red near the neeldes. To get the paint of the neeldes all you need to do is use some rubbing alchohol and papertowel. it will come off with soem rubbing. Then use the red model piaint and paint the back of the needle.
Now put it all back with neeldes off and the clear plastic cover over the bezeell off. tunr the car to ACC. Now put both rpm and speed needle on 0.. Turn ur car, drive around, pace urself with someoen else ot see if its right. you will probably be off by 5 mph and 300rps. If you are off by allot then take off the speedo needles, drive next to someone doign 30, and put ur needle on 30.
If oyua hve more questions feel free to pm me and i can go in greater detail. That and i am at work with a crappy keyboard so i am sure i have allot of typos
