I teed off of the oil port and used two pressure sensors one for the computer to run the other was the old style pressure sensor. For the water I added the water temp sensor at the side of the block where a threaded plug to the water jacket is. Haven't done the tach yet but there is a way. And I don't recall the procedure for it other  than a signal converter is required.

Here ya go. I did this instead of T'ing off of the port where the factory water temp sensor is because I have the truck front cover and intake and there was just no room for a T.

Thx for the pic,
Any special sensor, or just the same used in a 70-74 car?
Directly threads in, or is an adapter needed?

Happy to help, I had to figure it out on my own it would have been nice to have someone point me in the right direction. The sensors are both  stock for the era of the car. For the water temp sensor there  is a pipe adapter that steps down to the size you need for the sensor. You should be able to get one from the brass plumbing section of your local hardware or home store.

Good info, thx!
I guess I need to remove that plug and find an adapter to match to the sensor.
I'm in the middle of the swap, and it never seems to end.
The old saying really is true.......

The last 10% is 90% of the effort
