Source for new ECU water temp sender connectors
Hey guys -
Currently helping a local guy rebuild his engine, and of course some of the connectors on the wiring harness aren't so hot. Big one that is VERY commonly broken and sad is the green 2-wire connector for the ECU's water temp sender, the sender is in the back of the water pump housing.
Did some digging on the internet and then hit the junkyard up today.
Late 90's/early 00's Toyota 4-cylinder cars use the EXACT same connector. Some were green, some were grey, but it's the exact connector. I literally had to stop myself after I got like the 5th connector, they are so common.
I just went to the pick and pull yard and went to work with some snips. The connector is near where the upper radiator hose comes into the block, it's high up and easy to get to. Like pop the hood, unplug connector, cut wires, done.
You can either patch the wires into your harness or pull the pins out of the bad connector and pop them into the new one. I usually prefer the latter.
Also, if you look around, you'll find fuel injector connectors, TPS connectors, and a number of other ones. Many 90s Mazdas use the same fuel injector connectors, and they are SUPER easy to get to. Again, pull the pins out and swap the shell onto your harness.

Here is the end all be all thread as far as finding new compatible electrical connectors for the FD goes. I replaced my worn water temp sensor connector using the part number from this tread a few years ago along with quite a few others.
I have no idea why this thread is not a sticky.

PM me for any questions with this. I've built my own harness and have nearly all the part numbers for the engine harness and some of the others in a spreadsheet. Most of the engine harness connectors can be found here if your looking to buy low quantities. Motorcycle Terminals, Connectors, and Wiring Accessories If you're clever you can find terminals for all the connectors on this car including the IAC.
