Appreciate your kind offer to donate. There is a sticky at the top of the board (right now it is just above your thread) from Tim that delineates donations.
Oops, Tim is ahead of me he just posted a paypal link

Shy of a phantom MVAC technician dropping in, I am not sure how much more help I can be, at least. Would seem if you cannot find what you want on the FSM wiring diagram that you might be SOL.

I would again suggest a one month subscription to AllData.
You may also end up replacing the control module

Keep us posted

Thank you very much for the schematic. I appreciate all the help. I am beginning to think that the grey/red power wire make be broken somewhere in the harness so I might try making a new connection wire frrom the high pressure sensor since both would be receive a 5 volt charge when AC switch is activated.

Well my attempt to run a bridge wire to the evaporator temp sensor to the high pressure sensor wire didn't work. I had the engine running and merely connected the end of the wire to a mutimeter to read the voltage (5v) and the engine stopped dead and the starter would not engage. I disconnected the battery (-) trminal for 15 minutes and the engine, thankfully, started and runs fine. Not sure what happened but obviously the ECM didn't like it ! I found another '03 ECM and will replace the one in the car and see what happens.
The link to make a donation worked but Paypal gives the message that they cannot send money because they don't send money to that country?

It's set for the US only as the Paypal account is also linked to an online store. We do nto ship internationally.
