opti is fairly easy, i'll give a quick run down. the most complicated tool you will need is a harmonic balencer puller.

1. remove air intake, belt, radiator collant hoses from water pump and fold out of the way.

2. unplug anything thats in the way

3. remove icm and coil bracket. take note of how the ground straps are attached as they will need to go back the way they came off.

4. next remove the smog pump and bracket, you may need to pull the fans to have enough room.

5. next remove the water pump and take not of where the bolts go, a couple of them are different lengths.

6. remove the harmonic balencer bolts and use the puller to get it off.

7. remove the opti mounting bolts. there are 3

8. reinstall is reverse

the opti and the balancer only go on one way so you cant screw it up. it is wise to just replace the water pump since you have it off and inspect the opti harness, now is the time to replace that piece of harness if its bad.

if you need pictures go on shbox.com and go through the site.

i hope this helps
