VCCA Home Forums TECHNICAL - 1945 AND NEWER 1949-1954 Diectional signals

Hello All,
Has anyone installed a Guide 6004 turn signal unit? I have a '51 Stylline Deluxe that has an aftermarket (SignalStat) signal unit that works great except that you have to manually cancel. I found an original accessory unit in really good shape and am trying to figure the installation out and to see if I can use the existing wiring and just replace the head unit. The 6004 self cancels but does not have a four way hazard flasher that the aftermarket has. I downloaded the Chevrolet accessories installation manual and it does give a step-by-step install but it is very confusing- to me anyway. Any help would be appreciated.

I have the Guide Automotive Lighting Service Manual dated March 1, 1952 which includes instructions for the turn signals used which could be added to cars prior to 1940, and trucks. It specifically mentions Guide D-19, D-68, D-68A, Guide 6004 and Guide Direct-Signal Equipment. I also have the page from the 1951 Chevy Accessories Installation Manual with figure 188 for the 986514 Self Canceling Turn Signal. I believe I got that from the http://chevy.tocmp.com/1951accessories/51aim78.htm web page. In addition I have the YnZ instructions that came with the turn signal harness about 1984. Send me a PM and I will send you a scan of these. If there is enough interest I will post these online.

Thanks for the response. I tried the link you posted and it did not connect. I will send you a PM as you suggest. I appreciate the offer to scan these documents and sending to me.

I have emailed you the scans. Good Luck!

Got 'em. Thank you so much!

Guide 6004 came in several flavors. They aren't all the same. Colors vary, mounting systems vary, and most importantly the number of wires coming out varies.

The exact numbers escape me, but it will be either "about 4' or "about 7" wires.

The ones I have seen have all had the same switch inside, so if you are missing some wires, you can solder the rest in.

The difference boils down to this: Does the car need to share the same bulb filaments with the brake lights? If it shares, you need a switch with all the wires soldered on.

1) 12v goes to through flasher, and from there to the Guide 6004 switch.

2) The wire from the the third pin on the flasher goes to the little tattletale bulb inside the Guide 6004, behind the red or green lens.

3) Two wires come out of the Guide 6004 and go to the signal lights, one wire for the right, one for the left.

If your car has dedicated bulb filaments for the rear signals (and separate bulb filaments for the brake lights), thats all there is. You are done. If not, and you have to share filaments with the brake lights then....

4) The wires described in step three go ONLY to the right front and the left front, and..

5) 12v goes through the brake light switch, and the switched voltage comes out of the brakelight switch and goes on ahead to the Guide 6004.

6) 2 more wires come out of the Guide 6004, for the combined brake/signal lights on the rear. One for right rear, one for the left rear.

When the signals are off, the Guide 6004 has both rear signal/brake bulb filaments connected to the brakelight switch.

When you turn a signal on, the Guide 6004 disconnects one rear signal/brake bulb filament from the brakelight switch, and connects it to the flasher.

Thanks for the reply! I had a feeling that there may have been some different applications. I guess the designation "Guide 6004" only is a model number with several different part numbers for the same model depending on application. I will check the bulb configuration on the '51 as you suggest.

You mentioned the Chevrolet Accessory installation manual has step by step instructions, I don't have one of those, maybe I could figure out my problem from that, is there a copy on line anywhere that I could download. I am really confused with the diagram in the manual. I know my problem is just a matter of selecting the right wires to connect, since I HAD OPERATING SIGNALS BEFORE MY CONVERSION.

First I am a little dense, when it comes to computer tech, but what is a PM?, and would it be possible for you to send me a scan of these instructions you referred to with Jeff Maybe if If I see it ,I can figure out my problem. thanks, John

Click on my handle on the upper left of my reply and you can send me a PM (private message) and I will send you the scans.

I think I have it solved thanks to chevy50jim and bloo. I downloaded the installation instructions for the Signal Stat 900 and it shows where each colored wire goes. I know can replace the 900 unit with the Guide unit and just substitute the corresponding wires from it and attach where the 900 wires were spliced in. I will add the required additional wires to my Guide unit that were never installed. Thanks to both of you!!

This is what the VCCA and the chat site are all about - members helping members!

Hi Jeff
Glad you are finally getting this sorted out. Great bunch of folks here and ChevyTalk.

Both of you are absolutely correct and that's why I joined VCCA (and a couple of other sites). Now I just need you to come over and do the soldering and install. Just kidding. I should be able to accomplish this by spring.

Update: Thanks to all your help and a lot of studying the manuals/schematics, I successfully installed the Guide 6004 unit. And it works perfectly. All the signals light as they should and they cancel when the steering wheel is brought back to center. The only thing that did not work at first was the pilot light on the unit. Then I realized that in order to protect the paint on the column, I glued some thin vinyl to all the surfaces that touch the column. Duh, no ground! I put a small wire from the unit to a screw near it on the column and voila it worked perfectly. Thanks again for all your help.

Sounds like you mastered your problems, now I just wish I could get my turn signals working. I keep thinking it could be my grounds. . John
