I am replacing a 22RE (248k)with one that doesn't have the same style block. My 22RE is OME '86 truck. Replacing it with a used one from a car. So under the intake to the rear of the oil filter is a block plug sensor. Looks like no water to the sensor, no oil to the sensor, it just threads into the block. It has yellow plastic and a single wire lead. On the replacement block, there is no threads or pad up in the same area of the block. Is this just a heat sensor? Can I run without it? Would it work to fab a bkt and let it pick up heat thru a non-use motor mount? My camera isn't downloading now for some reason, but if I can get it to work, I'll add a picture.
