I'll be ordering a new knock sensor tomorrow. I do appreciate all the responses and help , thank you to all who have commented. I will respond more when I get a chance to work on my truck.

I'm not trolling bro. The weather here has been too wet for me to work on my truck. Sorry to leave anyone hanging.

Thank You for the ID. Again there is no sending unit at the oil filter. I will take some more pics after work and put them on here tomorrow. again thank you.

Try to attach pic but it tells me I have low memory and cannot.

And there is no sending unit where your pointing at. There is the block with a plug screwed in it.

No I do not have a light blue wire on that center connection. Only a yellow wire.

Tried to attach a pic but could not get it to add file. My Apology.

I believe I have found it. Two wires going to it and a completely bare wire. All three wrapped in a paper thin foil wrapping. It is on the driver's side. Screws in right above the seal of the oil pan. Plastic was dry cracked and the wires were dry and exposed.

I have not found anything unplugged or dangling wire harness ....

I will look for this pig tail this evening after work.

I could not find any thing around the filter or distributor. I know the book shows there to be one but mine does not. I have had the truck for 10 years. Never had the light come on before. Could it be on the other side of the motor? Truly has me stumped. have not been able to find any diagrams that might label what I'm looking for

I use 10w30 high mileage full synthetic Castrol. I let the truck run 3 or 4 min.

I did look for the sender. There is not one by the oil filter. There is a brass fitting there and a port that is plugged off where one , I believe, should be . But there is nothing there.

Recently I have been doing some fixing on my 87 Comanche. Inline 6. 4x4. Long bed. Automatic. I replaced passing gear cable , installed electric fans and removed manual fan. New plugs, wires , rotor, and distributor cap. New oil and filter. ( Not a fram) My oil light has come on . I went through my book it's a Haynes and there's nothing in there defining like where my sending unit or signal comes from I'm not very sure on how to check my oil pressure because it's just a dummy light on the dash so I know how to work on cars and I'm somewhat savvy with it but I'm not very electrical familiar any help would be appreciated where to start what to look at.

have a comanche 87 , in line 6cylinder 4.0 Battery light comes on when we turn the key on (didn't do that before). It will crank over but doesn't start. The fuel pump does not prime, no power to it. Changed the starter relay and fuel relay. I am stumped. Need help please.
