-the power wire for the ms should be cut into and replace the wire going out of the pcm on C1-11?
Correct.
-i think i might have to share the signal wire for the tps C2-21 and the crank pos signal C2-35
Yes, that will be spliced.
-C2-29 i think i have to cut and wire and wire to a 5v output from the ms (not sure where or what pin) and i believe it should be on the wire going away from the pcm maybe wrong though
You have an option here. Either leat the NGC computer provide the 5v or let the MS provide it. There's still a debate as to whether the NGC computer cuts voltages to certain devices. So, at this point nobody really knows. To be safe you could cut this wire and go directly to the MS 5v output.
-C3-3 and C3-37 both have to be cut and wired to ms pin 37 on the wire going away from the pcm
Correct.
-C2-14 and C2-11 both have to be cut and connected to ms pins 32&33 on the wire going away from the pcm
-C2-12 and C2-13 both have to be cut and connected to ms pins 34&35 on the wire going away from the pcm
That will work.
-C2-9 and C2-10 are for the ignition and i forgot which pin on the ms thsy go to but im assuming its cut those and wire in on the side away from the pcm.
Correct.

i think i might be set for wiring after that. if those questions made any sense please help lol. also, i know that ms can run fuel without spark fine without the ngc decoder, but how does it know when to inject fuel if it can't read the trigger wheel?
Fuel injection is not timed with the crankshaft at all. It doesn't need to be unless you're doing sequential injection. Since the MS does batch, it's not required to know where the crankshaft is.

also, how do i know that i have the ngc code loaded in megatune, is there something i have to click for ngc? or do i have to set up trigger points or something, im really confused on that part
When you have the proper firmware loaded into the MS and connect with megatune it will say "029v NGC3" on the megatune title bar. There's no menu item for NGC. If the NGC stuff gets real popular I can push to have the decoder added to the final release. For now, it's a seperate code base.
Setup the megasquirt as a 36-2 wheel with the following trigger points:
Angle: 65
Trig A: 11
Return: 16
Trig B: 29
Return: 34
Confirm with a timing light! I still don't think anyone has done this....
