VDO Install Guide - 2/3
'85 K10 Suburban

BASIC PROCEDURE:

 

  1. Remove the dash panel
  2. Remove the clear plastic gauge cover
  3. Remove the black plastic gauge pod cover
  4. Remove the gauges
  5. Disconnect the printed circuit connector and two wired lamps
  6. Remove the gauge pod
  7. Using Dremel tool, trim the backside of the four small gauge pods of the dash panel until the gauges will fit through the panel and sit as you like them.  Install gauges using screw on clamps.  No trimming is necessary for the two large gauge pods - the 4" gauges will fit right in.
  8. Using drill with ½ hole cutting bit, drill mounting holes for inserting light indicators (the Radio Shack lamps).  I drilled four holes: blue for high beam, blue for 4WD, red for parking brake, and red for choke.
  9. Install red and blue Radio Shack lamps into drilled holes.  They just slide in from the front of the panel, and they are a press fit.
  10. Install green Radio Shack lamps into the turn signal indicator holes on the back side of the dash panel.  Just press them in from behind, and they are a press fit.
  11. Using Dremel tool, cut out the innards of the gauge pod.  You need to keep intact the outside frame of the pod, the mounting holes for the dash panel, and the light socket that is located between the old speedo and fuel gauge pods.  This light is for lighting the shift indicator on the column.  The pod is important because it is necessary for mounting the dash panel, but if left intact, it interferes with the mounting and wiring of the VDO gauges.
  12. Clip factory wires from printed circuit connector.  From the Painless kit, install molex plug connectors and other connectors as needed on factory wires.
  13. Disconnect factory speedo cable from transmission tailshaft and discard unless you want to keep cruise control.
  14. Install VDO speedo sender into transmission tailshaft.
  15. Run sender wires from sender to dash.  If you are discarding the speedo cable, you can run your wiring through the factory speedo cable clamps (my truck had three of them, two on the underside and one at the bottom of the firewall).  I kept the speedo cable, and so I still followed the factory speedo cable routing by mounting additional wiring clamps onto the speedo clamp mounting studs.
  16. If used, install old speedo cable into back of VDO sender.
  17. Install Painless harness onto gauges.
  18. Install modified gauge pod.
  19. Install modified dash panel with gauges and wiring installed, and hook up electrical connections.
Hopefully all is well and the gauges and lights work.  If so, drive off, find some mile markers, and go calibrate that speedo!
