Where is the oil pressure sending unit? Wanting to put manual oil gauges. Engine 4.3L V6. I can send pick
The oil pressure switch for the gage should be next to the distributor on the driver's side.
This switch also is in the fuel pump circuit. Find another spot to use for oil pressure or put a tee in the line to share the port.
Check by the oil filter or the oil filter adapter for a plug that you can use for a manual switch.
