You need:
Digital dash
Pigtail for the 34 pin plug
Wiring diagram(posted in link above)
Ither make a quick connector or hard wire the new 34pin connector in.
Easy,however,keep in mind,the digis have alot of issuies of missing segments and missing readings all together,I went through 3 clusters in 2 years time,granted they were all used,but its just something to think about.
Oh and I recomend wiring in the dimmer,cus its so freaking bright at night if you dont.
