Oil pressure switch vs gauge sender can both work correctly in either location (top of bellhousing, or above filter adapter). It's oil temp senders that don't work well in low-flow or blind-ended passage locations. Good pressure readings available in either place.

Left one coolant temp sensor to gauge. Right one coolant temp switch for overheat alarm. |

Well I ditched whatever was there for the MSD ready to run stuff. Just out of curiosity this is what was there. Did this use the knock sensor? Mercury is a big outfit and it could be that it's cheaper not to "think" about each engine separately and just wire them all the same. Shotgun affect. Can't go wrong with that.:D

So I stripped out the brass plug above the oil filter location at the block. The socket on the plug, not the block. Anyway, I would still like to have the alarm go off for low or no oil pressure and am wondering if I can install the sensor at the filter head? I would assume if this will work that I would NOT install it where the arrow is pointing in. If there's another location please let me know. Thanks for the help.

Is brass plug a allen head or hex head? If it's and allen put a punch in center of the plug and hit it a few times with a hammer. This will shock it loose, then drive a bigger allen in and remove the plug. If it's a hex head get a "turbo socket " and remove the plug.
