I have a 1970 f100 originally manual steering and manual brakes. I converted to disk brakes and power steering parts out of a 1970 f100 as well. I put a 1979 460 c6 automatic trans. Curious on if I could use shift linkage out of a 1978 f150 with a c6. As well as the steering column out it. Any suggestions on aftermarket shift linkage if donor truck doesn't work.
Sorry for the Confusing way I put that. Haha. I have a 1978 f150 with a c6 it's a "donor" truck looking to take the tilt column out of that truck and put it in my 70 f100. I also want to use the shift linkage.
The tilt column will be designed to couple to a Saginaw PS gear box. The column will require the shorter stamped steel bracket on the engine side of the firewall.
Shorter power steering bracket on the right. "POWER STNG" will be stamped on the bracket. My '69 manual steering column bracket on the left.
You will also have to change out the smaller manual steering column-to-firewall seal in the interior of the truck to the larger seal.
You will also need the splined and bolted flange that goes on the steering shaft side of the rag joint. Without that flange, you will not be able to couple the tilt column to the rag joint. (My '78 tilt column didn't have this flange when I got it. I had to install a Borgeson stainless steel steering joint instead).
Your '70 will have the NSS (Neutral Safety Switch) on top of the steering column, near the firewall, on the interior side of the cab. This was the location of the NSS on the Ford trucks through 1977. In 1978, the NSS was removed from the column and installed on the side of the C-4 and C-6 transmissions. You will have to either jumper the NSS out or, you'll have to run (4) wires from the transmission-mounted NSS and run them back to the main wiring harness connector inside the truck, behind the instrument cluster.
Jumpering out the NSS is somewhat risky since the truck will be able to start in ANY gear. The second thing is you'll lose your backup lights, since they are also activated off the NSS.
The Dentside column connector (fixed or tilt column) will have a single wiring connector. Your Bumpside column will have (2) separate connectors going to it and the Bumpside connectors won't plug into the Dentside column connector.
I don't like cutting and splicing the factory harness wires on my '69 F100 Ranger. When I put the '78 tilt column in my truck, I got around this by making up a short 'patch cable.' I took the turn signal from my '69 fixed steering column and cut the wires off several inches back from the (2) connectors. I got a column connector off the main wiring harness side of a Dentside donor truck --also cut the wires off several inches above the donor connector.
I spliced the Bumpside turn signal wires/connectors to the Dentside column donor connector wires. I took the completed patch cable and plugged one end into the main '69 wiring harness and the other end into the connector on the '78 tilt column.
Bumpside turn signal wires/connectors clipped from my old '69 turn signal switch on the left. Dentside column connector clipped from the main wiring harness of a Dentside donor truck, on the right.
Splicing/soldering the connector wires together and then covered the joints with heat shrink.
Patch cable installed between the '69 main wiring harness connectors and the turn signal connector on the '78 tilt column. I tucked the cable up behind the dash, where it's out of sight.
I was able to use my existing '69 F100 linkage, between the C-4 and the tilt steering column.
I cheated in the blinker switch assy. I bought a new one foe the 69 and put it in the 78 tilt so I didn't have to mess with figuring out the wiring.
I got a new '78 tilt column turn signal switch because I will need the second horn wire/contact for future use in running the cruise control signals through it. '77 and earlier truck turn signal switches just have one horn wire/contact.
I went that route also, because I was unable to figure out the hazard switch wiring.
(by dablack00) http://fordification.com/forum/viewtopic.php?t=21570 I finally finished wiring up my 79 tilt column in my 71 F100. The only reason I'm finished is because the inspection is up and my horn hasn't worked since I did the switch. Now all is working.
I saw the post on the 67 wiring, well the 71 wiring is even easier. My column doesn't have cruise. Just tilt.
79 white red is hazard switch. I didn't use this one. I kept the hazard switch on my dash. You could easily wire the 79 column switch in if you like.
79 Blue/red is the indicator light. I didn't hook it up. If you want to hook it up, just splice in to your dash lights. No big deal.
79 yellow = ground for the horn. The 78/79 horn has two wires. The yellow is the ground, so ground it out.
79 dark Blue to 71 Blue yellow
79 light green to 71 light green
79 orange blue to 71 orange blue
79 light blue to 71 light blue
79 green white to 71 green white
79 green orange to 71 green orange
79 white blue to 71 white blue
Thats it. No big deal. Just took me a while to figure out the horn thing. All the other wires match up color wise. 78/79 Tilt Column Wiring (taken from a forum thread) LBell101: I'm putting a '79 tilt into my '67. I have the '67 wiring all figured out but I'm not sure of the original wiring placement on the '79 column. The column has cruise control that I plan on using at some point and I think that is what is throwing me off some. It has the curved connector with wires as follows:

Does anyone know where each of these wires goes or what it operates? Also, I did do a search and found some info but nothing for a cruise tilt column. Thanks! ------------------------------------------------------------------ The major change between the two era's of columns is the hazard light switch, which is on the column of the '78-79 column and on the dash or in the glovebox on the earlier trucks. The '78-'79 non-tilt column's wiring and harness is the same as the tilt version, except for the horn circuit. When you plug the column harness into the main harness, what was the horn circuit would now control the cruise control. The main control box for the cruise control is located inside the cab on the firewall. The horn would then (still going through the cruise control circuits) be operated through a relay which is attached to a dash brace behind the instrument panel. In addition to the cruise control's control box, there is one for the brakes. To add cruise control to your truck, and utilize the cruise features built into the column, there are several parts required:
the switch on the brake pedal which disconnects the cruise control (non-cruise trucks have the brake light switch mounted onto the side of the brake pedal, but will be substituted for the style that mounts on the vacuum booster pushrod. The cruise shutoff switch will then mount in it's place on the brake pedal)
