Hello All !..I have searched and searched the internet for my answer & I find myself coming back to this forum looking for help and its been very helpful ....Can anyone show me how to repin a 91 suburban speedometer to work on my 77 Chevrolet for my VSS . I did a LS engine swap from a 2003 Silverado 5.3/4l60E/ with an NP241C …I have an INCOMPLETE 91 Suburban Cluster with JUST the speedometer from a 91 Suburban..I wanted to know if I can swap the Water and Volt gauges into the 91 Cluster or Vice Versa …?...Oil Gauges has the copper line running to the gauge …Thanks In advance

This is in the tech forum. There are posts showing the DRAC as well as the cluster pinouts.
