Question Honeywell zone valve wiring

I have a gas boiler with Honeywell aquastat 8148J and 2 White Rogers zone valves, which needed replacement, and 2 standard 2 wire thermostats. I have purchased, and soldered in 2 new Honeywell 8043E zone valves. 2 red leads and 2 yellow leads extend from zone valves and 8148J has terminals TV, T, W (which is strapped to both Z and TP). I have read the documentation but am not completely certain of wiring. No example shows my exact situation. I have a wiring scheme worked out but would like to be absolutly sure before I proceed. I called Honeywell for support but they do not want to assist a do-it-yourselfer, which kind of defeats the retail plumbing supply, Home Depot, Lowe's aspect of life. Please let me know if you can help.
Thank you,
Lew

Of course we can help. As should the Home Depot sales people. They want to sell things that aren't easily installed, but they may take the money and run.

All I can tell you without pulling up the docs on the auqastat is that the 2 yellow wires of the zone valves go to the motor to open the valve and the 2 red wires are from the end switch. Those termonals close when the valve is open to start the pump. The red wires should go to the T terminals on the aquastat.

The rest should be fairly straight forward. The power supply in your aquastat will power the valves. You just need to get the right terminals.
