Square nose headlight wiring question

Postby Bob McCarty » Sat Dec 15, 2018 12:38 pm

On the later Cubs, does the harness loom just butt up against the round male connector on the headlight, or would there have been heat shrink or something else covering the junction between the two? Or does the loom not extend out the hole in the hood?

They originally used connector body 899385R1, which can be seen here:

They are too big to fit through the wiring hole in the hood. So you can imagine what happened the first time the hood had to come off. I don't think I have ever seen an original on a tractor. I bought the remaining supply from one source, which wasn't very many. I have also found some by stripping them off old auto wiring harnesses.

the wiring was part of the harness and went through the hole in the hood right to the connector Jim linked you to, the spade connector had a locking tab on to keep the connector on the terminal, most chopped it off, all you need to do to remove it is to insert a small screw driver to release it

I have the connectors, just wondered where and how the loom ended. My wires were cut and spliced and I'll try and return them to original status.

I clearly didn't read the original question close enough. The 6-volt tractors had pigtails from the headlights that reached in through the holes in the hood and plugged into the main harness near the fan shroud. The loom comes pretty close to the connectors. On the 12-volt tractors, the main harness ends with connectors that plug directly into the back of the headlights. Neither of my 12-volt tractors have loom extending through the holes in the hood, just two individual wires. I didn't try looking/digging under the hoods to see how far the looms reach. Based on the 6-volt looms, they probably come fairly close to the hood holes. The drawings in the parts catalog show a short loop of individual wires under the hood.

Note that I am using 6-volt and 12-volt rather than round and square hood as the wiring change was with the voltage change not the hood change.
