Remote Start AUX Sunroof/Power Windows

I did a search before posting this and found some similar situations/questions but no specific answers. I have a RS with a trunk release (aux) wire (that I can't use for my trunk) that puts out a negative split second pulse (but it says the trunk release botton can be held down for a continuous charge). So it says I can hook it up to a sunroof or PWs. Would it be too much to tap into all three (2 windows and sunroof)? My sunroof's motor shuts down once the roof's closed. - I should also mention it's the type that tilt's and slides. Can I simply hook this aux wire to all these things? Or I'll definitly need a relay for the juice it will require? Thanks for any input on this matter. Mike P.S. My car's a 1989 Toyota Celica GTS. My RS unit is the CT-3360 (ProStart) - Yeah, yeah I know. ;)

is the sunroof a neg. trigger and the PW also a neg. trigger i have found that most are a pos. trigger you might want to find that out.
