1966 V74 Hazard Flasher Kit

[CC Rider]

I bought one of these hazard flasher kits for my '66 Caprice. These are the electrical connectors it has. They are curved.

Unfortunately, it does not appear the tilt column harness has similar connectors for me to plug this in to.

It appears I can't use this kit. Is there anything I can do? Is there another place to look for a curved connector?

Thanks.

Does this help?

The picture Lee posted is essentially what's in the 1966 assembly manual. Here's a picture from my assembly manual.

The 4 way flashers goes inline with the flasher wiring that comes off the steering column. You need to look for the 2 support bars under the dash that help stabilize the dash/steering column. If you follow the wiring you'll see the existing wiring with those connectors clipped to one of those bars. You basically unplug the connectors and put the 4 way flasher inline. If you need other pics let me know.

Thanks guys. I've seen those diagrams, but I cannot locate those curved connectors. I'll crawl under the dash and will look again.

[CC Rider]

Several months ago, I removed the dash housing. This is not the best photo, but I don't think there is a wiring harness attached to those dash supports.

Rick,
I'll crawl under my dash tonight and take a look. It's been a while since I've been under there, so I'll need to check.

tilt is unique because of the turn signal switch 64-66 has an external switch that hangs on the column for tilt ..like in your pic..so on non tilt it loops thru..on tilt its special



the flasher is one or the other..tilt or not...and the tilt switches bring a premium..

i went thru this decades ago..with skylark gran sports..

for tilt one end is curved the other is 5 sided..

for tilt the flasher is equipped with the right connectors..

i thought i had one for tilt, but realized i sold it..

you could make a jumper harness, ive done it..the wire colors are right, you need a couple tilt harness ends and yours could work

Something like this?

I took a look under my dash tonight to refresh my memory. The wiring that comes off the steering column is a short harness that looks similar to the harness that Lee linked in his reply. The dash harness has the curved connector as part of it and the short harness from the steering column plugs right into it. The flasher plugs in between the dash harness and the steering harness. If you don't have the curved connector as part of your dash harness it may have been modified. Follow the wiring that comes from the steering column and see where it goes.

Here's another page from my assembly manual. It shows the connector as part of the harness (Directional Signal Switch) and are clipped to one of the support bars as I mentioned before.

yes Lee..thats what an A-Body uses, i know that jumper is there if you take an untouched car apart....

from my experience.. youre on the right track, the thing is on a flare stat made for tilt, the ones i have had and searched out, the 5 sided connector is on the flasher unit..ive had and used a few but on A body's, or at least on the ones ive used, and i only had flare stat..thats the company that GM branded as their own..and i am pretty sure the aftermarket prob made jumper harnesses to get around the problem

and i remember that 65-66 are the same but 64 is diff...some of the others are pretty cheap and cheesy from the 60s and they scare me..i would only use a flare stat on my cars

need to look around a little more and see what others have run into....im more of an a body guy

i will look around, i remember seeing this type of prob on the PY forums, and the guy posted pics of everything, and i also have seen a for sale ad there and that flare stat was a tilt and he had great pics...if they didnt purge the ad, i will get the pics

[CC Rider]

Thanks everyone. My next step is to remove the wire wrap and see what is under it.

Rick:

Did you Caprice come from the factory with a Tilt Wheel or is this an option that was added to the car after the fact?

Yes, it came with tilt.

[mssl72]

Rick, I did a little more digging and checked with a buddy of mine whose a '66 full size expert. He works for GM and loves the '66 Caprice most and has been into '66s since the 80's. On '66 Chevrolet full size cars the connection point for the signal flashers were all the same. The steering column didn't matter. My car for example came with a standard column. The previous owner put a tilt-tele in it. No difference in the connectors on the main harness. My harness has no mods to it. As the assembly manual shows the curved connector should be clipped on that support bar. Let us know what you find.

[CC Rider]

After finishing an I-Car Class tonight, I peeled back the original wiring harness wrap. There are no curved connectors anywhere, and there is no splice and dice wiring in that bundle of wires, except for 2 thick red wires, and they were not done in an amateur manner. The six wires from the turn signal switch go into the harness with no butt connectors, soldering, or electrical tape repairs.

The top pin is a white wire that is routed towards the dash face. The green and yellow wires go to the fuse block. The bottom row of the turn signal connector has a light blue, dark blue, and purple wire. The two blue wires are routed to the block and the purple wire is routed towards the dash face. I assume it goes to the flasher under the radio. The flasher has a purple and brown wire.

Not sure if this photo is helpful, but maybe someone will see something I do not.

This flasher kit has the same colored wires as mentioned above, but also has a gray wire and a black wire not found on that six wire turn signal connector. Haven't taken the time to locate a gray wire, but there are plenty of black wires.

For extra safety, I would really like to make this kit work out, but I don't want to cut up a good, original harness. Felt bad enough removing the wrap. Seems to me I will need more than one bumper harness to make this work, and I am still trying to figure out how to hook this kit up into series.

Yup, car stuff is hard. Thanks for your help guys!

[CC Rider]

Hmmm, might be having an ohhhhhh moment.

So I'm looking at the N33 tilt wheel page. I can see where that jumper harness in the above link would work. The black wire appears to be for the horn. Still have to figure out what the gray wire is for.

If my thought process is correct, I may have to cut / modify this harness and insert the correct plugs/connectors. Hmmm.

Edit....OK, the jumper harness solves half of the problem. All I need to do next is find that stacked connector (the female connector?) . I could remove the existing 6 pin connector, remove the terminals from it, correctly install them in the female connector, and add the black horn wire. Still need to see where a gray wire fits into this.

[mssl72]

Interesting. I'm looking at the page too. It shows right there on the page the curved connector that's part of the "chassis wiring harness" for the directional signal connection. That's weird that it's not in your car. Take a look at UPC 12, sheet D2. About midway on the right hand side of that page you will see the signal connections with the curved connector. :hmmm: I'm still digging. There's got to be a reason...

Oh, the gray wires are usually an indicator light, like dash lights, heater control, ignition switch. Check and see if there's a light for the shift indicator.

[CC Rider]

My chassis harness does not have that curved / stacked connector. :dunno:

Also, I seem to have one "extra" dash light / metal socket, and no bulb in it. It is wrapped around the harness. I've tried to locate a possible missing light somewhere, but all components that are supposed to be lit are lit.

I guess the red knob lights when the dash lights are on?

I've ordered what I need to make this work. I should not have to cut anything, just change some spade connectors.

[mssl72]

The more little things you find make me wonder if your harness may have been messed with a little. It's very possible that somebody removed the curved connector and added the other connector on in order to remove the short harness that would normally be there. Does the extra light socket have a grey wire? The red knob lights up when the 4-ways are activated and flashes along with the signal lights.

[CC Rider]

I think you are right Mark. At least someone did not hack up what is there.

Oh, and the extra grey wire with light bulb socket is for the ignition switch. I googled 66 Caprice igntion switch light. What a neat feature. I'll stick a bulb in it and plug it in.

So now I am waiting for the jumper harness and the stacked connector to arrive. The only issue I have remaining is finding a gray wire to add into the harness bundle.

If you guys want pictures, let me know. :smile:

[mssl72]

If someone changed the ignition switch it may not have the bulb hole. There are replacements that don't have it. Maybe that's why it was wrapped around the harness. The assembly manual wiring diagram shows the ignition switch light. You should pick up an assembly manual. They are a great help for some things.

Bought some male terminals, crimping tool, jumper harness, and a curved connector from a parts harness, I'm ready to modify the harness.

https://photos.smugmug.com/My-Cars/1966-Caprice/i-RNWt5MM/0/072aa4d3/X5/20170522_200457-X5.jpg

This is what I am starting with. No bumper harness, and the black horn wire had no connector.

https://photos.smugmug.com/My-Cars/1966-Caprice/i-PX66J8H/0/e01a22e1/X5/20170522_200521-X5.jpg

After switching the six wires from the pyramid connector to the curved connector using the male terminals and adding the harness end of the black horn wire, I thought I could finish this tonight. However, I need a female terminal for the other end of the horn wire. Thought I already had some of those. Damn.

Once I buy a terminal, I'll connect these plugs and make sure everything works properly before adding the flasher kit.

[mssl72]

Looks good Rick!

[CC Rider]

Thanks Mark.

I finished the install tonight. Haven't decided whether to hang the little tag or not. Leaning towards not, unless I'm at an appropriate car show.

Everything is working as intended. Glad I was able to get from there to here and make this kit work.

[mssl72]

Congrats, nice job Rick!!

[Lee Stewart]

Way to go Rick!

Did you buy that Acc. Manual?

[CC Rider]

Thanks guys.

I will buy that manual.

edit - just ordered it from the provided link. Thanks Lee.
