1991 D21 Instrument Cluster

[Lakehimself]

My 91 Pickup has the bare bones instrument cluster, I want to put one in with a tach. A few questions:
1. Is it even possible
2. If it is what clusters work, I assume from 86.5 to 93 works, as long as it wasn't an automatic since mine is a 5 speed
3. I have a few extra connections behind the cluster and I assume thats what they are for, if not how much extra wiring will it take.

Thanks.

1993 will not work, all the connections are different. The extra connections are for the tach and a clock. It is possible and missing member mrecoolgar started a thread about this subject. Search his name and it should come up.

This is a popular question and I believe a search should show you the build thread that have been done.

Here is a link that I got on a quick search. Hope it heads you in the right direction.
