TR2/3/3A Control Head Rewire

A fan belt breakage destroyed my horn and turn signal wires just outside the steering box. I have a replacement harness.
I can find numerous posts and articles on how to attach the wiring harness to the control head.
I assume you feed the wires down the steering shaft and out through the steering box.
Do you use a stiff wire or something similar to pull them down?
Do you have to remove the bullet connectors to get the wires through the olive and nut.
Any gotchas other than exploding springs and screws so small they should be in watches.
I do have corn head grease for the steering box - thank you John Deere.
Thanks and keep on drivin!
 
With a new harness, the bullet connectors should be staggered so you only have one connector and one wire at a time occupying any given space in the tube. The wires are slightly twisted in the harness, so you spin the harness slightly in the direction of the spin as you go down so as to make the wires collapse against each other to minimize diameter. You can use heavy mono line or light wire to pull as well, but you will need to fix each connector to the line to avoid a traffic jam. At least so I recall, but it was 12 years ago. I do remember how surprised I was at the ease.

It gets real easy if you un-solder the nipples then slide it through. IMHO Other methods lead to heavy drinking
and swearing.

Lube helps. The big no-no is to not allow the wires to change positions as you stuff…they must stay aligned as they initially start. I have never needed to pull, twist, or remove the bullets…just line them up and push about an inch at a time.
 
Some of the aftermarket wiring harness are bigger than the original and are a challenge. If the new harness is a just little bigger, I would remove the bullets and pull the wires out with a small wirer attached to the end.
