Tail Light Wiring on 26 Coupe

[dunoon]

I'm not exactly sure how the tail light wire goes. I'seen in vendors catalogs a wiring installation kit for the taillight. Not sure what the flat piece with the 3 holes and spring do and also the grommets with pigtails is for. Any help would be appreciated.

Richard, the taail light wire is a long single wire. The rubber grommets are used to protect the insulation at various points where it is attached as it heads rearwards. Typically, a loop of wire twitched around the grommet, and the tails on the wire are used to attach the grommet with wire included to various places under the car. Two places they are fitted to are the centre of the front running board support. There is a convenient hole drilled there to pass the twitching wire through. Another is often twitched around the battery box top irons. The flat fibre piece has the taillight wire threaded through two of the holes with the third, possobly smaller hole, to the rear. The spring hooks into the third hole and is used to keep tension on the wire so it cannot flap about. Typically the spring is hooked to the loop in one of the split pins used to retain the nuts on the rear spring mounting at the frame cross member.

That is how I have seen them positioned on our Canadian sourced cars.

Richard, the 26-27 tail light wire goes thru the woven sleeve with the starter cable from the starter to the starter switch. Then folllows along the frame with 2 or 3 small porcelain insulator rings that are twist wired to the frame. The vendor equalivent is rubber gromets twist wired to the frame. At the rear crossmember the flat strip and spring pull the wire to hold in slight tension. The wire passes through the 3 holes in the flat strip which binds it up enough to hold it. From the flat strip and spring it has a bit of slack, passes through a hole in the fender to the tail light. There are some older threads from past years with good pictures. If memory serves me one of the porcelain gromets attaches to rhe rear running board bracket just inside the frame, maybe borh running board brackets.

Ford Service manual has chassis wiring diagram, and Service Bulletin shows same enlarged.

The coupe and runabout have a small hole in the left rear fender flair to the lower body, pass the tail light wire into the hole to bring it to the tail lamp.

Thanks for the info

Some wire a small dash light in series with the tail light so if the dash light is out so is the tail light, like the old Christmas tree lights. It is a good small monitor.

Richard, my apologies for a bum steer in some of my response. our RHD cars have the starter switch on the opposite side, so the cables and looms have to switch sides under the car. Hence the different route for the wire. The insulators and the 3 hole fibre piece are likely the same, but will be in different locations.
