First, I'm not a Realistic representative.

*** Following is for information only.***
* You can take a small low powered audio source and connect spare speakers to listen for output.
* or a multi meter to check which wires have some sort of drain in reference to each other.
* When volume is set to low you should be able to check for voltage output on wires. Note polarity. Try connecting only left side.
* Connect right side then check again.
* Sorry, unable to find (free) manual download. Every site listed has been blocked or deleted. You may be able to check ebay for manual. But like most old electronics this falls into "Antiques"

Electric Testing Techniques You Need to Know

blue from mains should (connect on the switch ) go to blue wire and brown to brown OVER the switch The switch shouild not connect brown to blue on the powercable . use even a multimeter or
You should know ofcourse where the right points are sometimes there is a little connection diagram on the switch self but not large enough to see or letters on the connectionpoints L and N phase (brown wire) and zero (blue wire) from the motor and electronic assembly if the switch have only 2 contacts then connect blue wire direct to blue wire and brown to brown OVER the switch.

You can go to Autozone.com, and obtain a wiring diagram.
If they have the Repair Guide for the vehicle, they'll have the wiring diagram also.
[I checked, they have the wiring diagram for 1994 Chevrolet G20 3/4 ton Van's]

If you are not familiar with reading wiring diagrams, you may want to view the first two instructional diagrams,
How to read and interpret wiring, and Common wiring diagram symbols.

If your van has a gasoline engine, the wiring diagrams for the 1994 G20's start at the 27th diagram down.

Car Radio Wiring Diagrams and Car Stereo Wiring Diagrams

If you can't get a wiring diagram... locate the wiring harness for the lights.... use a multimeter to test the wires....even one of those ice pick type of testers with the light on it will do
have someone step on the brake.... whichever wire has voltage is the brakes. next have them turn on the right turn signal... check for voltage on the other wires... it will of course be off on . do the other side the same way. all you have left is the wire for your running lights.... turn on the parking lights for that. also if i remember right there is a connector already there for the towing package. even if you didn't order that with the vehicle it's likely there. check in the side panel where you store the jack.

I have a Jenn-air, and the switch for blower and light is on top, front. the switch has 4 connections on the bottom, and viewed from the bottom, the white wire goes at 12 o'clock, the red and brown wires are in the top left corner (paired with the white one) and the black wire is at 6 o'clock, and the blue (double wires) goes in the lower right corner (paired with the black one). If you have a continuity tester, the switch is a dpdt, and white is connected to red-brown (double wires) OR black is connected to blue-blue( double wire).


Hope this helps.
