Hello,
Before proceeding, keep in mind that the 1FZ-F's engine block is different from the 1FZ-FE. Senders and other components may bolt in the former but not in the latter.
The temperature sender goes where the leftmost arrow is. The next port, marked with the other arrow in the picture, remains unused in the 1FZ-F.
The No. 2 temperature detect switch goes where the circle is.
The 1FZ-F block has no provision for knock sensors, of which there are 2. They require an SST to remove, but that is another story.
As for the connector for the water temperature sender, the manuals I have at hand refer to it as W12, gray, 1 terminal. Alas, no part number. I will try to post an image from the manual later -my computer is not helping with that now. I think it is possible to get it from an electric parts supplier.
Last but not least, I think it is worth trying to clean the old connector. Dirt may have built up inside, preventing proper contact.
Hope this helps.
Juan
