I'm just now about to attempt the bypass. Hopefully it works...and yes, I'm using that kit.

Still have to do the bypass with that kit. I'll try it in a few minutes here.
Can I just use standard relays instead of the 451? My stepdad has some car relays and doesn't want my wasting more money on parts

The 451M is a nice module but not mandatory. You can use relays.
Does the car have EKE? The relay diagrams are on this site.
Soldering is fun!

Alright, Soo it looks like I'm using standard automotive relays for this.
What else do I need for them for lock/unlock/trunk? Fuse? What exactly?

RKE makes your job easier with Type A locks.
Three relays wired with this (-) to (+) polarity conversion diagram at top of page :
https://www.the12volt.com/relays/page1.asp
One will use R/S (-)Lock input and connect to the cars (+) Lock wire.
One will use R/S (-)Unlock input and connect to the cars (+) Unlock wire.
One will use R/S (-)Trunk Release input and connect to the cars (+) Trunk release wire.
All can be supplied with one +12 Volt constant connection fused at 10 Amps.
If you have three 1N4004 or 1N4007 diodes, you can add them to the relays to protect the DEI R/S (-) 200m
a outputs from the relays coil collapse pulse. Add the diode across Relay Pins 85 to 86 with the band towards Pin 86.

Do they need their own separate constant and fuse?? What if I don't use a fuse? None of mine have popped yet....
And I don't know which wire is my trunk release

You only need a fuse if you smell smoke and the car stalls. Of course it's too late then to add a fuse.   2001 Sunfire Passlock 2 Bypass - Page 2 -- posted image.
It's always best to add a fuse to protect things. One fuse and then a 3 way split going to each relay. You will only be energize one relay at a time so 10 Amps is adequate. It's a lot of wires with many connections, so take your time and keep it neat.
The (+) Trunk release wire is noted in the Bulldog Security wire listing. Use your meter to verify all wires. With the Trunk wire you will see a 1 second (+) pulse when the trunk is popped.

It doesn't say which plug (purple, brown or blue) the trunk release is in

You can use your Digital Multi Meter to probe the Black/White wires at the BCM until you find the correct one or
you could just run the Trunk Relays' output to the Trunk Release Switch in the car and make the connection there.
Trunk Release    BLACK/WHITE (+)     AT BCM OR TRUNK RELEASE SWITCH
