I have a Bluprint LS 3 and the FF cluster gauges. It calls fo the temp sensor and oil pressure sensor to install into the block. Can I wire off the LS sensors already installed. They look exactly the came. I don’t see any empty ports to screw in the FF cluster sensors.
If anyone knows where to add the additional sensors or wire off existing sensors. Please help. Thanks

You can't combine two sensor wires onto one sensor. For the oil pressure you could install a tee to accommodate both sensors. As far as temperature ports on an LS I can't help.

The LS sending units are digital and talk to the ECM. Standard sending units/gauges are analog. I used the Can-Bus gauges from Speedhut. They are daisy chained together and plug directly into the OBDII connector. No additional sending units and the wiring is greatly reduced.111914111915

I'm pretty sure the LS3 oil pressure gauge is an analog 0-5 v signal.
I don't know what Blueprint does, maybe they added sensors for the FF gauges?? Can you post a pic of the sensors on your engine?
My FF gauges are the American Platinum ones, they came with sensors. I drilled and tapped holes for the oil and temp sensors.

The LS ECU does not use oil pressure for anything. So you can eliminate that factory sender.

But the ECU does use the water temp, so you need to keep that in the stock location.
