No actually for the 97 DX which is what i have, you only have the fuel,temperature and the what u call it.. ? well speed, (don't know the word in english) and all 3 of them come with 3 little circuits. all u have to do to replace a needle is get that one circuit. and that's it. i'ts like a sensor.
But I have to wait for next week in hopes of finding another car....

I any case I'll put my pictures from my gauges later on as well has my new halo lights.

 

this is how my glow gauges look.
I uploaded the pic...

 

they look pretty good, Im just not a big fan of all the junk in the middle of the gauge. that solid light between the numbers and the needle seems pointless and to me makes it look cluttered. thats the main reason I didn't get mine off of ebay. But it is a lot better than the stock gauges!
