Help installing 90 Burb Cluster in 79 C10

[dayman]

I did an LS swap in my 79 C10. 2006 LQ4/ 4L80E.

I want to install the cluster out of 90 Burb so I have electronic speedometer. I searched the forum, but can not find what I need for a 79 C10.

I used a Painless harness for the swap.

Do I need to re-pin the 79 connector for the cluster? and where do I connect the VSS input?

Another possibility -Is it possible to just replace the old speedometer with the 90 Burb speedometer and wire it directly to the PCM and not change out the complete cluster? I have all my analog gauges working with the old cluster.


Any help will be appreciated.
