So, I have a 1994 Chevy Silverado 1500 2wd with a 350 cu in TBI with a bad coolent temp sensor. The old one kept reading 160, so my gas mileage sucked. For the life of me I can not find a replacement one that is an exact replacement. They keep giving me these 2 pin coolant temp sensors. Well, the one on my truck is a 1 pin design, but has the weather proof connector. No where that I look can I find the right part. So, I buy one of these two pin sensors, yank one pin and file down the weather proof connector so it would fit in there, and nothing. Idk if anyone has ever run into this problem before, but I'm extremely frustrated. My question is, I have a new 2 pin coolant sensor, I need to go and get a connector for it, but when I do, can I just run the original wire into it, and then run the second wire to ground, cause I imagine that's what the second pin is for, ground. I would like to know beforehand before I go and buy a $14 connector, the outrageous prices for these connectors is going to bankrupt me. Any help is much appreciated.
