Please help with wiring confusion!

I have nearly finished my wiring but I am confused by a few things.

1. Dash Harness - The dark blue wire labelled 'water temp' clearly goes to the gauge. I trace the wire down and it goes through the 'Sending Unit Harness' and I am unsure where to connect this. Does it connect to a sensor? The only sensor not yet installed is a fan sensing switch. My fuel injection system had a sensor that needed to be installed, and this went in the thermo housing. So, no room to add a sensor for the gauge.

2. Main Harness - Where does the dark green 'fan thermo ' wire connect to. My kit includes a 'fan sensing switch'.

3. Oil pressure - in the 'sending unit harness' it looks like the grey 'oil press' wire goes to one of the sender terminals. Does the second terminal just get grounded?


My engine is a 351W.

Thanks!

Your gauges ( if you ordered them) come with the appropriate senders for these wires. Find another spot on the intake for the water temp. Install the sensor from the gauge pack and attach the dark blue wire to it. Same with the oil pressure.
Oil pressure ports is on the driver side of the engine near the timing cover. I believe its a 1/4 Pipe tap hole.

The fan thermostat also needs to be in the intake manifold. FFR should have shipped the sensor with the kit. The green wire will attach to it and trigger the fan.

Thanks Mike. I think I am missing the water temp sensor as I can only find a fan sensing switch.
I have already mounted the oil pressure sender to the engine - i was unsure if the second terminal is just grounded.

Yes. Grounded
