Hi,
I was going crazy trying to find the wire the hooks up to the temp. sensor on the rear iron, just under and to the left of the oil pressure sensor.
I went through the service manual and found out this is connector EM-33 with a yellow wire with a white stripe.
Some pictures on the forum showed a yellow wire with red rings!
Also found out that EM-33 is the only round connector on the passenger side wire harness.
Here's what I found:
Dash temp gauge wire
When I removed the harness from the engine, I saw a long single wire hanging out.
To protect this flimsy wire I tucked it into the split wire loom.
Then promptly forgot about it!
After studying the wire diagram I decided to untape the harness where I did see a round connector.
There it was, I forgotten that I "protected" it!
I am now waiting on a couple of rolls of harness tape.
The color of the wire near the connector was covered in grime and looked black, after cleaning it looked whitish without any stripe or rings.
Only as I removed the tape and loom to follow the wire did it finally appeared yellow with a white strip!
This is my first time messing around with a engine harness. Live & learn.
Just wish the learning part was easier!

Reason: replace stripes with rings
Hi,
I have been wrapping harness tape to make things look a bit more professional. In all this unwrapping and re-wrapping it appears that I have shorten the harness slightly.
I went to connect the wire to the sensor and it almost reached, just a sixteenth of an inch more! POP, I now have the connector in my hand.
It broke right at the connector, no wire to splice. I spent the evening trying to find a suitable 4mm female bullet connector with a pigtail. It should not be that hard, I ordered a couple of items that might do the trick.
They were not quite the right fit. I came up with this:
Carefully cut the plastic on the original connector, top and bottom to remove the terminal. I have had no luck trying to de-pin these 37 year old connectors!
Open up the area that crimps to the insulation and remove what you can of the original 18 gauge wire. I left the inner crimp as is. I didn't think it would survive trying to pry it open.
I soldered a length of 18 gauge wire onto the old crimped area and folded the end crimp over the new wire insulation.
Now to super glue the cut plastic parts back on, leave it all in a small vise overnight.
Add some heat shrink over the mess and I have a usable connector with a pigtail!
Does your connector look like the one pictured? If so this is available, I might even have an extra. Trying to recrimp would be awfully hard. It would be more likely the terminal would simply break as soon as you begin to pry.
