LS1 connector pigtails
I came across these on eficonnection website and kind surprised me!!!!!
His website lists 3 different connectors for Oil preasure sender/switch.
1. Oil Pressure Sender.
I have this one.

But.....Maybe i am ignorant but where does these 2 plug into ?
2. Oil Low Sensor LT1/LS1

3. Oil Pressure Sensor LSx

Re: LS1 connector pigtails
You don't need the low oil level sensor (big sensor on oil pan) cause you don't even have a light for it in your dash. Number 3 is useless as well if you are using your 3rd gen oil pressure sensor.
Re: LS1 connector pigtails
I havent seen anything close to connector number 3 on the LS1 harness.

Re: LS1 connector pigtails
3rd Gens didn't have an oil level sensor so there was no light
.
No number one is the one you will use. Number one is for the 3rd gen, number 3 is the same thing for the 4th gen (I think lol).

Re: LS1 connector pigtails
We're talking about the oil sensor on the top of the block towards the back of the valley cover right, and not down on the oil pan?
Re: LS1 connector pigtails
#1 is used
You should have this in your stock harness in 3 wire form. The function is the same
#2 is the big tan thing in your pan. Leave it unplugged, you have no provision for it
I have never seen #3 in any of the harnesses I have disassembled or modified

Re: LS1 connector pigtails
None that I saw, and Ive stripped quite a few
Oil level light requires a sensor mounted in the oil pan. No third gen that Ive ever seen had one

Re: LS1 connector pigtails
Oil Pressure Sensor. This is used to bring the oil pressure into the data stream. The early LS use of this sensor is common among Corvette applications. Just about all LS engines today use an oil pressure sensor.
The 3rd gen cluster will only accept a one-wire sender.

any way to add them to fbody harness ?
Re: LS1 connector pigtails
Why add it to the F-Body? The gauge can't read from the sensor.
