The 8045-20 & 8145 are 240V timers.
My maintenance buddy at McDonalds says the defrost timers are interchangeable, BUT I have not wired these particular timers.
You may want to post your question to a paid answerer who specializes in refrigeration:

This being said:
The 8045 is for 'Electric Heat Defrosting'
The 8145 is for 'Hot Gas Defrosting'

I posted the manual:

I also posted the 8145 and 8045 wiring side by side:

The wiring changeover looks like the following:
Hot1 on 8045 is connected to terminal N => move this wire to terminal 1 on 8145
There is a jumper plate on 8045 that connects terminals 1 N 2
Jumper plate on 8145 connects terminals 1 and 2
If jumper plate is missing on 8145, use jumper wire to connects terminals 1 and 2
Hot2 on 8045 is connected to terminal X => move this wire to terminal N on 8145
Other wires on 8045 that are connected to terminal X => move to terminal N on 8145
Thermostat on 8045 is connected to NC terminal 4 => move this wire to NC terminal 4 on 8145
Heater on 8045 is connected to NO terminal 3 => move this wire to NO terminal 3 on 8145
Terminal X on 8145 is bare since this goes to cycling limit switch which is not used on 8045

The wiring diagrams appears below:

Tim, Could not find your model, look at attached video and see which wire you are not locating. maybe it fell off or is stuck in the body some were.

I am trying to wire a double toggle switch one would work an outside light and the other the garage light. help!!!!

I can probably help you, but I need more info. Are you replacing a single switch that operated both of these lights together? Do you have 3 black wires and three white wires in the box now? Are the 3 white wires all connected together? Were 2 of the black wires connected to one terminal of the old switch, and 1 black wire connected to another terminal of the switch? ----- I'm doing lots of guessing here so that you understand the kind of info I need.

Can't Remember where wires go.

probably these wire nowhere connected if you have no wireless lan adapter. Usually these two wires join to built-in antenna in screen.
