Replacing turn signal switch?

I just ordered a new switch from DC for my 67. Was curious who has changed one out. Is it easier to pull one wire through the column at a time or could you tape all the wires together at several spots and pull all of them through at once? Thanks for any tips you guys have!

I pulled wires through from steering wheel side.I wouldn't tape them in several places. In fact I think it needs to be flat to pull through. I tried all bundled tight the first time and the got stuck. Then I laid it flat and taped in one spot and used a pull string, worked much better.

Snip the wires off about an inch or so above the connector, so the colors of the individual wires are visible.

Tape the wires together, than tie a long piece of heavy string to them.

Pull the switch from the column, tape the wires of the new switch, then tie the string to them.

Pull the string from the bottom of the column, the wires will feed down without binding up.

Plus...with the snipped off wires remaining in the connector, you'll know which colored wire goes where.

Using the method, Ford techs could R&R T/S switches in 15 minutes or less...and this included removing the steering wheel.

You don't have to cut the wires. They can be removed from the plug. If you look on the plug side you will see a tang that can be depressed with a small screw driver. I'm pretty sure I did what Brian did, tape them flattish. I even taped a coat hanger wire to the bundle to get it thru the lower end of the column, untapped the coat hanger to finish the job.

That's exactly what I did, but I had the luxury of having the column out of the truck at the time. A little flat tip screwdriver to push the retainers and pull the wires out of the connector. Draw yourself up a diagram before you do it so that you can put them back in the same order that they were in the connector.

Numberdumy has the best method. I also have the right tool to disengaged the wires from the plug, which I'm sure the Ford tecks did.

3x. I've always clipped the wires just above the plug also. You can tell which wire goes where that way. And I've always used some of the old wires to pull the new wires down the column.

Great idea.

Once I had a new switch for a 72 and decided it would work in a 68. Everything looks the same, some wire colors are different. Did not function but after some head scratching and a test light, I got the wires shuffled around to make it all work right. Was darn glad I had the tool that time,lol.

As much as I respect Bill and his wealth of information, it sounds like he worked with some of the mechanics I knew years ago. I cringed when I saw them clip those wires on a brand new switch/harness and splice them back leaving an ugly mess. I was too young back then to know about the pin removal tool, but knew there had to be a better way. A good self made diagram of the wire colors and plug positions makes for easy reassembly and a nice factory look when complete. I've done a few and it's not that hard to do correctly. As one service manager used to say, "If you don't have time to do it right, when will you have time to do it over?"

Neither the old or the new T/S wires were spliced.

The method was to cut the old wires off just above the connector, leaving enough that the individual colored wires were visible.

When the new switch was installed, it was EZ to determine which colored wire went where in the connector.

Pull out the old wires, insert the new wires. No splicing of any kind necessary or required.
