Howdy, I bought this tilt column from Tri-C engineering forever ago, and I'm finally getting my '34. back to the point where I can use it. Anyway, I'm in the middle of wiring the car with a Ron Francis harness and discovered that there are only 3 wires for the turn signal switch? I think the black wire is for the horn, and there are two brown wires that must be for the left and right. There also is a really thin white wire. The problem I see is there is no power wire to hook to from the flasher. I tried to get some info from Tri-C, but apparently the fellow that designed and built these columns passed away in 2014 with all the info in his head. Can anyone shed some light on how to hook the turn signals up?
Where is the turn signal switch? A quick look at that will tell you what goes where. However, you will have to figure out how to separate front and rear bulbs, as well as brake lights. Otherwise your front turn signals will light up when you hit the brakes. Unless you use 3 filaments (3) bulbs in each housing. The way I see it, one wire goes to flasher , one to left bulb, one to right bulb and one to horn relay.
Thanks for the response! The turn signal switch appears to be inside the tube and not easy to get to. I'm guessing that it is probably just a double throw single pole switch so I think you are probably right about the separate bulbs.
You can get around the seperate light problem with a converter piece for hooking up trailer lights. Sent from my SM-T350 using The H.A.M.B. mobile app
Colors look like what GM used on the 60's and 70's steering columns. If so the colors are: Black-Horn relay Lt. Blue-L. front turn signal Dk. Blue-R. front turn signal Brown-Em. flasher Purple-Turn signal feed White-Brake light feed Green-R. rear signal yellow-L. rear signal
I've got one. Ordered it new from Tri-C some time ago and just about to put it in my car. It came with an additional relay box with four relays (I believe), along with the other side of the GM connector and instructions on how to integrate it into and existing harness. Tomorrow, I will take pics of the set up and instructions and post here (unless someone beats me to it).
Hey Flambe that would be fantastic! When I bought mine I only got the column, no instructions or anything else...... THANKS
I was going to reply to your thread but haven't had time until now, but I'm glad you're getting help. I'm not particularly a fan of adding relays but this is a case where they're needed for a reliable system. How you integrate it into your wiring and how many relays you need will depend how many/what kind of exterior lights you have. There's also a way to add a 4-way flasher function to this if you want one by adding a 2PST switch. If you are still confused after getting this info, PM me and I'll help you sort it out.
Ah, but that's not what he has. It's left front, right front, left rear brake/turn, right rear brake/turn. You use the switch to drive the relays.
The GM van column is the only GM column with the shift quadrant on the column (P,R,D,N etc) and it is illuminated. There will be a brown wire for this lamp that you wire to your dash gauge lamps.
Wow, 20 lbs of **** in a 5 lbs bag. Why didn't they adapt/use GM's cable operated turn signal switch?
My mistake letting that GM column show in the photo... I did not think about it confusing the issue/ Its for another car...
Well, the 'directions' are a bit less than useful.... Plug in the magic box this way and it all works. No mention of the 'magic'.... LOL Give me a few days and I'll generate a diagram explaining the 'magic' and options. Meanwhile, you can identify the four wires coming out of the column by checking for continuity. One should be the horn, the wire sticking out of the end of the shaft. The other three will be left, right, and power/common. Turn the switch to left and check for continuity; two wires should read. Turn it to right and check again, the one wire that's used for both sides is incoming power/common.
