VDO Install Guide

WIRING NOTES:

For wiring, I was working off a Chiltons schematic, which is not entirely adequate or correct, and some notes from other ChevyTalk members who had performed similar installs. Here is what I came up with in my truck and how I matched things up with the Painless harness and with my custom lights. The numbers are based on the numbering found on the factory printed circuit wiring harness connector.

2	Instrument Lamps	Gray	Brown
3	Ground	Black	Black
4	Ignition (hot wire)	Pink w/ black stripe	Red and White striped
5	Oil Pressure	Tan	Lt. Blue w/ black stripe

7	Fuel Sender	Pink	Splice to Pink
8	Ground	Black		Not Used
9	Temperature	Dark Green	Light Green
10	Ground	Black		Not Used
11	Left Turn Signal	Lt Blue	Lt Blue
12	Right Turn Signal	Blue	Blue
13	Seat Belt	Yellow		Not Used

16	Ignition (hot wire)	Pink w/ black stripe		To P-Brake Lamp
17	Parking Brake	Tan w/ white stripe		To P-Brake Lamp

· #17 Wires My truck had two wires here.

· #18 Wires - My truck had two wires here.

· Factory ground wires - Only one ground wire is needed to hook up to the Painless harness. I left the other two wires unused.

· Fuel sender wires - I ran all three pink factory wires to the pink painless wire. I heard that only one of the #18 pinks is needed, but

· Tachometer My truck did not have a factory tach, so no factory sending wire to available to use. I ran my own wire from the HEI terminal to the Painless harness.

· Seat Belt - I left the #13 yellow wire unused.

· Choke - I ran the #15 blue choke wire to one terminal and the #6 ignition wire to the other terminal of one of my red lamps.

· Parking Brake - I ran both #17 wires to one terminal and the #16 ignition wire to the other terminal of my other red lamp.

· 4WD indicator - There is a separate harness and bulb for this indicator. This harness has a brown wire and a white wire running to it. I clipped off the factory connector and ran each wire to my one of my blue lamps.
