My engine is installed and running, but I have four questions, and I can't find this info antwhere

1) How do I specifically wire the V-tec? (I had a s model w/a f22 motor, and I converted from an A.T. to a 5 speed, if that matters)

2) How do I wire up the knock sensor (spelling?)? I'm geting a check engine light and my computer (also JDM) is throwing codes.

3) How do i wire the relay/selenoid for the vacume lines of the fuel pressure regulator? I assume this is needed for the V-tec engagement but I can't find any info on it.

4) Not as important as the other questions.
I had to permanently set up my old wireing for the A.T. in the park circuit so I can start the car and it will release the key. This works fine, however the indicator lights on the dash (the ones by the speedometer that tell what gear the transmission is in park, neutral ect) are now blinking. Not a big problem, but annoying none the less. Can I unplug the bulbs? will the circuit remain intact or will it short if I do that?

I know this is a lot to ask but I'm desperate. My mechanic friend is helping me with this for me at a great discount, but the more time it spends at his shop, the more it costs, so I need anwsers fast. Thank you to all who can help in advance.

Don't know any answers first hand; maybe check out: http://h22hybrid.20m.com/photo3.html About half way down shows some diagrams that may help.

1. the vtec pressure switch has two wires (red & green) the red one needs to be ground and the green goes to the ecu swich a4 i want to say (not positive)

2. the knock sensor needs shielded wire or else it'll always throw a code. You can find some at radio shack. Ground the shield somewhere and the other wire goes to pin D4.

3. You dont have to use the FPR, but if u want to here's how to hook it up. One vacuum tube comes out of the intake manifold and goes to the top plug of the FPR, the bottom plug connects a vacuum tube to the fuel return line. As for wiring, there are 2 wires (black/yel & wht/yel). Black goes to a 12v source and white goes to pin A10 on the ecu. But like i said you dont need it. I took mine off. If you choose not to use it, just run a vacuum tube from the intake manifold to the fuel return line.

4. Is the D4 light blinking, or all of them? If its just the D4 light that is blinking, that is indicating a problem with your tranny.

The entire swap is detailed in the FAQ section under writeups in the Prelude forum.

I'm not sure what light is blinking, the car is at the shop. I know its a drive light because its green, and only one is blinking, but not sure which light it is, i'll find out tomorrow. I swaped out the A.T. for a 5 speed, and in order to get the car to run we had to permanently wire the old A.T. wiring to park permanently (it wouldn't run, and I couldn't get the key out .) If it is the d4 light, do you think it actually is receiving a problem signal from the new transmission, or is the old A.T. wiring to blame? (I know you can't tell me for sure, obviously you can't see what I've done, but an experienced opinion would be great)
