gauge cluster help

i have a 90dx hatch, and im getting a si gauge cluster for the tach. there are 3 plugs on the back, should that hook right up in place of my current setup, or since i had no tach will i have to run a new wire to hook it up?

It is plug and play but make sure you get one out of a 90-91 Civic/crx

yea it should be a friend bought it and he as an 88 so it didnt work, so he is giving to me free :-)

so i wont have to wire in the tach for sure?

Yeah, i've done it a couple of times, just unhook the old one and reattach the plugs to the new one...
