Help! Oil Pressure & Wayer Temp. Sensors

Rjaaaaaa · Oct 29, 2016

So I have the motor back in and I want to get rid of the small gauges that the PO installed for the oil & water.
Bought original sending unit to connect the dash gauges but now I can't find the original wiring or plugs ??? PO may have chopped them and tucked them in the wiring harness ??
Can someone shed some light on where to look for these wires. Water temp. might be in harness that goes to dist. ??
Thanks

Hey thanks a lot that narrows down the search.
I bought a water temp. sensor but it has a 2 wire connector but I was looking around the interweb and found out that it's the wrong sensor. The correct sensor has only one wire and I think I found that wire, still looking for oil pressure.

BTW I did bookmark that site, good info.

Both wires are on the drivers side and are just push on connectors
