The Stovebolt Site Forums The Shop Area The Electrical Bay 5-wire signal harness

I appreciate earlier discussions on 7-wire signal harness and Chief's full color wiring diagram. My problem is I have a 5-wire harness coming from my turn signal switch. How do these connect? '54 3100 Chevy.

I think their is a diagram showing the hook up under the electrical section.

took a look at the site and found out the diagram needs to be updated...... Here is wiring coming out of my AutoLamp 9000 signal unit:

Red and Green are signal wires I don't know which is left or right at the moment because I didn't break out my tester.

Orange wire from signal unit goes to the "P" terminal on the flasher

Black wire from the signal unit goes to the "L" terminal on the flasher

The "X" terminal post on the flasher goes to power supply

Grumps,

Does your '54 have the stock (original style) GM accessory turn signal switch?

chevy1,

Does the AutoLamp 9000 have the same wiring as the original accessory switch?

In the 50chevy.freeserver.com site listed above, which diagram is the 5-wire diagram (I see a 3-wire and a 7-wire and a general diagram)?

Grumps,

If you have the original '54 signal switch, I might have a diagram and will post it if I do.

My '54 3100 Chevy had an after market turn signal when I bought it. I am relacing it with what I understand to be an original style accessory; that is there is a casting that slips over the steering column below the steering wheel. It has the 5-wire harness. When it is installed it looks like it always belonged there.

I posted some info about a 5 wire SignalStat model 700 here . Your colors may not be the same but I imagine it works the same.

The 50chevy website doesn't show the 1954-55 wiring to hook up the signals sorry.

The 9000 model is a clamp on unit for pre 54-55 series since the 54-55 have the upper bell that encloses the signal unit. I check my 1954 Manual and the addition and it doesn't show the signal wiring. I guess I'll have to buy the schematic so I can list it on the website.

If you have a volt/ohm meter you can find the power lead and then the left and right signal wires by moving the lever.

TC,
Thanks for the great graphics. This is the exact application I needed. You have been a great help. Thanks to the others too.

This search has provided with some information, but need some further help.I too have a auto lamp 9000 unit. It has a red, black, green/white strip, and a orange/green strip wire harness. Mixed in with this is a 3 terminal 12v flasher. The flasher does not have any terminal ID number/letters on it. From above post, Chevy1 outlines the following:
-Orange wire from signal unit goes to the "P" terminal on the flasher
-Black wire from the signal unit goes to the "L" terminal on the flasher
-The "X" terminal post on the flasher goes to power supply

Is there any way to test my flasher to identify which terminal is the X, L, and P?? IF not, do the new flashers have these same terminal identifications?

To All...
Looking at the Business End of 1 of my spare flashers,arrange/turn the flasher so that the terminals are at 9:00,12:00+3:00 position.
9:00 is X
12:00 is P
3:00 is L
This is a Tung Sol # 535 6 Volt flasher and Echlin is the same
I believe that 6 or 12 volt flashers have the same wire diagram.
It wouldn,t make sense to change the socket orientation.
Regards,and hope this helps

With a 4 or 5 wire switch you will have to have separate rear lights for the turn signals.

Excellent help, I'll try it out tonight.

ONe more question, since I am converting to 12v. I have a 12v generator, and voltage regulator installed. I also have a voltage regulator for the heater motor, and changed the lightbulbs to 12v. What other gages, or accessories will i need to install a volt reducer inline?

A voltage reducer seems to the pretty standard in the power feed to the fuel gauge. The horn is usually OK, but any and all bulbs need to be swapped..dome light, dash indicator lights..any bulb you can think of.

Your coil should be changed to a internally resisted 12 volt unit, or a ballast resistor should be installed ahead of a 12 volt unit. The ballast reisitor setup requires additional wiring.

Thanks atomarc. Not clear on the coil suggestion. I have a 12v coil, and have already hotwired the motor to run and dial in. THe motor probably has about 30 minutes of actual run time. I did not install a ballast resistor, nor a internally resisted 12v coil. Can you provide more detail to this, including the additional wiring mentioned? FYI, I have a 45
GMC 1/2 ton for what it's worth.
Thanks

The resister is available from any parts store. It came on all 55 up cars & trucks up to about early 60,s when they built the resistance into the harness. Wire it in the wire from the ign. switch to the coil & mount it on the engine side firewall. It,s best to put a bypass wire to bypass the resister when starting but is not nessesary.
