Manual steering column into auto truck

[1971ford]

WHen i put the highboy chassis under the '69 i swapepd the column with it of course. The old column was automatic so it had the neutral safety swich wires/plug. The manaual column (truck is now a 4speed opposed to the c6 it was) has some other wires. I haven't looked at it much but how do i go about hooking my manual column wires up to my '69 cab's wiring harness?

You will have to do some wiring tracing. The color coding should be the same from one column to another, although there may be more or less. Also, you will most likely have to remove the plugs on your installed column. This is easy to do by depressing the little metal tab on each pin, then pulling the metal pin / wires from the back of the plug. Once you do this, install the proper column plug into your wiring harness, then connect each color coded wire into the column plug that corrosponds with the wiring harness plug.

Sounds confusion but it really isn't. I've done this several times with good results. The turn signal portion of your switch should be the same but there will most likely be wires from the switch that will not be used - such as column mount flasher, etc.

wasnt the frame a 71 or 72? if so the column tss wirign will have different plugs than your 69 column will have. the 69 uses two plugs vs the 70-72 uses a single plug. checking with the wiring diagrams can give you the colors needed to figure out what goes to what.

Ryan,
Are we talking about he NSS wires or the TSS wires. I got the feeling your talking about the NSS wires and looks like others are thinking TSS wires...

[1971ford]

YEp the chassis is a '71, body is a '69... looks like i'll need to grab a new harness?

I'm going to have to investigate this matter this weekend so i can answer your questions without guessing, I'll be back!

Same number of wires doing the same things for the TSS... all you have to do is swap out the connectors like "Mach428" stated above...

I looked at the the plug coming off the manual column (7 wires/pins, square plug) and the plug from the truck's harness (for automatic NSS, 4 wires, 3 male 1 female in a line) and they are nothing alike. The plug coming from the manual column has 7 wires and the truck's plug has 4. I figured I'd splice the wires together for now but none of them are colored the same. The truck's harness plug's 4 wires are red and black varients and the one coming from the manual column are all different colors. Now what the heck do i do?

[fordman]

the 67-69 tss plugs are different than the 70-72 plugs. the 67-69 uses two plugs coming out of the column. the 70-72 uses one plug for the tss. the nss wiring is only present on a automatic column. the dash wiring is the same for the nss plug or the nss bypass plug. here is a picture of the nss bypass plug for a manual transmission. that is the shape of the plug you will want to look for under the dash.

The manual column doesn't have a NSS those 7 colored wires are for the TSS (Turn Signal Switch)! The manual uses a jumper like Fordman posted a pic of.

So here's the dealio... After my last reply i went and looked at it some more, and grabbed my automatic column that was in the truck before. I noticed it has the two plugs, one square with 5 pints and one 2 pin plug. I found those plugs under the dash. I figured those wires that were in those plugs needed to go to the wires coming from the manual column. 90% of the wires color coding matched right up so i cut the plugs off and sliced them. SO was that the right thing to do? those 2 plugs are for turn signalers that i spliced together? Or did i screw up.
I'm way too confused on this.
Do i need that jumper to be able to start the truck? Can i make one for now? (just run pieces of wire to each wire end in the plug?)

[fordman]

yes you can make your own jumper that looks like the jumper i posted. you just need wire and some electrical ends to do it. on your turn signal wiring using the plugs that match the truck wirign was the right thing to do. except i would have just depinned both sets of connectors and swapped connector instead of cutign iwres. but what you did does work.

[1971ford]

THanks... got two little pieces of wire and stuck them in the plug like that jumper and now i can fire the beast up inside the cab! with a screwdriver, but that's another story.

Still no turn signals though, i must of spliced the plugs together wrong somehow...

[1971ford]

Ok so I grabbed NSS jumper plug from the junkyard and got it on there so the NSS part is done.
Now for the TSS, I forget which but either the harness or the column has 7 wires and the other has 10. Most of the colors are the same so i just spliced those together (once i get it to work ill put plugs in) but hwat i am not sure about is for example there are two red/black wires on the side that has more wirse than the other. Do i splice these two red/black wires into the one red/black wire? or does one not get used?

[fordman]

that doesnt sound like the thing to do. i would look at the wiring diagrams fo reach tss and that should tell you which wires go to what.

Yes, there should be 2 Red/Black wires on the truck harness that will both hook together on/to the 1 wire on the TSS. One wire is from the brake switch and the other is from the hazard switch for the rear brake lights.
