Default difference between 99-00 si and ex engine wiring harnesses

Hi,
Is the only difference the dizzy plug? And how do I wire the si dizzy plug to the ex harness since the si dizzy plug has 9 wires and the ex dizzy plug only has 8?

Thanks for any input!

Distributor plug (you can get one from any '96 - '98 harness '96 - '01 integra harness or '97 - '01 CR-V) and the O2 sensor wiring is routed a little differently requiring that you extend the wires.

Thanks!

You will need to run the blue wire from the igniter in the distributor to the tach test lead on the driver's side rear of the engine bay (its a single blue wire with a rubber cap over the plug right in the corner of the engine bay.) If you don't do this you will not have a working tach.
