I was running both senders in the water cross over right on either side of the thermostat. The AFR heads I use on one of the cars (Chevrolet) doesn't have provisions for a sender.

On the Pontiac dad chose to have both senders at the water crossover so he could hide everything under the intake. He didn't want a sender in the head.

Eventually, after we got the EFI reading correct temps on both cars that matched both mechanical gauges, the extra gauges were removed. Ended up adding sensors to monitor fuel pressure and oil pressure too so those mechanical gauges could also be removed. Now the Snipers monitor everything on the handheld and it cleaned up the clutter of extra gauges.

On a side note, those 0-100psi pressure sensors tend to read a little lower than the mechanical gauges, opposite of what I found on the coolant temp sensor.
I had fuel pressure set at 60 psi on the Chevelle with a very nice (expensive) autometer mechanical gauge. When I added the holley 0-100 psi pressure sensor, which ironically costs $100 by itself, it would show 57 psi. Since I had the cars base fuel table dialed in really well at the 60 psi I had with the mechanical gauge, I left it be, removed it, and just monitor it with the Sniper, and realize it might be reading 3 psi low. Oil pressure was spot on (mechanical vs Sniper sensor)

Dad had a similar issue but with oil pressure. He felt the oil pressure on the Sniper was lower than usual the other day on our 300 mile cruise. I temporarily hooked up his Autometer mechanical gauge and it seemed to be maybe slightly higher. Problem with a mechanical oil pressure gauge is it's very slow to change, the Sniper changes constantly and reads down to the tenth. Regardless, I changed the scaling on that sensor in the tune to mimic more what the mechanical said.

So these pressure sensors seem to be hit or miss. Some seem okay to me, others read a little low.
