I'm posting a pic of the ID tag for my truck so all the info is available. In my effort to replace the water temp sensor ( Code 22) I've made a mess of things. The wiring and plugs are so brittle (33 year old truck) that they were just coming off the sensors in a way they shouldn't. Part of that is a 70 year old man trying to distort his body in ways he shouldn't just to get to the rear of the engine. Part is the age of the truck. So bottom line I need to replace everything I can back near that water temp sensor. I think one of the harnesses went to the cold start ignition but I'm not 100 % on that. I just want to redo the whole area back there. Any help, pics, diagrams, part numbers would be much appreciated. Another duh question. A 3/4 or 19mm socket goes on the new sensor like a glove. However I wasn't able to get a socket on the old one to remove it. What am I missing? My back will take a couple days to want to make another stab at it but I'm determined. And what's up with shops having a policy of "we don't work on anything before 2000"? I thought older vehicles were easier to work on, not harder. I digress........Thanks in advance if anyone has the time. Cheers..............
Use this link to look up part #s. When you find the diagram with a part you're looking up, click on the 5 digit # to get a pop up with the 10 digit Toyota part #. The 10 digit # is the one you'd use to order parts. If you order online at a Toyota dealer it's A LOT cheaper than calling in an order.

Thanks for taking the time here. I actually have the hard copy of that exact manual for the 1993 truck. It has very little information about that area. I'll look again. That second link is great if I ever figure out which breakdown. Cheers..........
89422-35010 Water Temp Sensor....... I have one
89462-20040 Switch, Start Injector Time ------- Prices all over the place. After filtering ones coming from China out they're listed for $55 to $215. That's a bit confusing. Getting closer though thanks to your help.
This sends a signal to the coolant temperature gauge inside the truck. I need a part number. As you can see the top has been broken off. The plug is wasted also. So I need both part numbers. Or tell me where it is in the service manual. Thanks,
