window module au93-4 on 99 camry

I am trying to install a window module " omega au93-4" on camry 99 2.2l
the manual is here https://a248.e.akamai.net/pix.crutchfield.com/manuals/514/514au934.pdf
I know where the window switch wires are but don't know where motor wires are. It looks like that the motor and switch wires are the same. can I put 2 wires on one cable?

Do I need to remove all the door panels to connect the motor wires?
or easier way to install?

My second question is my alarm is prestige aps-920a. it says that I need to use a relay. How do I hook up with a window module?

thank you

could you check this relay informaton correct?
85: (-) lock pulse
86:12v
87: no connection
87a: window module negative activation input
30: ground

From your 2 questions, I would question you trying this on your own and seek professional assistance.But let's answer your questions.
1) Yes of course you have to remove all door panels, especially if the Camry uses (like most other Japanese) data signalling from driver's to satellite switches. You have to go to the wires which control each motor directly.
2) Wire side. This refers to the motor wires. If you cut it, one side will go to the switch, the other is the motor side. Logical, yes?
3) From the relay list, you shouldn't need it.
Most alarms have a grounded when armed output, not familiar with yours but it's a good brand and there will be one. Either that or a spare timed aux output. Either will connect directly to the closer's negative activation input.
