Warning: long Post...

I have a few more outstanding questions before installing and using my kit

Installation:

1) Which fuse(s) should I connect the kit too?
Arming
Mallory
TPS
Remote Bottle Opener
Heating Blanket
Purge Button

2) Can they all go on the same fuse or should that be distributed?

3) can I use one switch to start
example: I open the bottle (switch one).
I arm (button two)
bottle heater on
Mallory on
TPS on

5) Calibrating the TPS switch:
The manual states the following:
After all wires are connected have an assitant open the throttle to maximum and hold it. If the LED is "ON" using a small blade screwdriver, turn the adjustment screw clockwise until the LED goes out, now rotate the screw one full turn into opposite direction. the switch is now ready for use. Close the throttle, the LED should go out.
Question:Should the engine be on for that and if so wouldn't that hit the limiter and potentially damage the engine while standing?
Or should the ignition key just be turned to allow electricity but in that case wouldn't the engine be flooded with gas and if so could this hurt the engine?

4) Drilling the hole for the blow down valve...
Do I need to be concerened about the fuel tank or any other obstacle? (planning on installing the bottle on the right side of trunk)

5) Where is the fuel line located and where should I slice in?

6) I got the mallory switch today (the new 646 digital one) and it's pretty big. What's the best location for that sucka.

Usage:
1) the manual states you can not spray longer than 20 seconds at a time. How long do I have to wait before I can spary again?

2) Can I arm and activate the system while driving?
since the system is usually activated via wot instead of the FnF push button.
Can I get this feature by just arming the system if I want to spary while already driving
(this is a more retorical question....)

Please no hating or flaming...some of these might be ignorant questions but I have not found any answers on those.

Thanks

the answers are there search a little harder. but i will answer a couple. i bought a distribution block and tied everything to one lead off the battery. they told me to check the tps with car running but i just did it with key on works fine.iff youre driving wot with the switch off and you flipp the arming switch you will spray so mount the switch where you can reach it will driving.and dont drill into anything with the blowdown tube hole. i possible remove on of the rubber gromment and poke a hole in it. most ikely youll never use the blowdwn tube anyway .the tps swicth is wired in series with the arming switch.the instructionswith the bottle opener and heater are way to complicated i guess the want it only on with the system armed. but all you really need in a hot to the switch switch to the device and ground.use lighted switches so you won forget they are on. its not specified anywhere but i just give it acouple of minutes to spray again.if you cant find the fuel line have a professional install the kit. is not hard but some of its a little tricky. there are plenty of post here on nitrous i know cause ive posted in them.SEARCH.

thanks you answered the majority of my questions, I'll search around some more for the rest. I'm planing on having a pro install the kit but I want to be part of it and learn, also most likely the "pro" who will install it won't have done it on a celica so the more I know in advance that's specific to my car the more I can help and the less money and headache it will be
