Pull off the cable attached to the negative battery terminal, grab all vacuum hoses from the distributor's vacuum advance diaphragm (if it has one), and remove any clamps and wire connection bits from the distributor, writing down where everything went before you get started again. Keep the original wires connecting the coil, but remove all others, except the 1988 and 1989 Integra models. Find the number one spark plug wire terminal that stands out from the others on top of the cap when the distributor is in place; if nothing's noted, follow the wire from spark plug one to the cap. Turn the engine until the rotor tube points toward where you'll plug in number one spark plug wire. To align the distributor properly, put marks directly under the rotor tip, both on the base and the cylinder head, in direct line with its top. Take out the distributor by disconnecting the spark igniter wires, then undo the attach bolts with care: don't rotate the crank while doing this. Use compression pressure at the number one plug hole to return the crankshaft to its original TDC position if it started moving while you removed the distributor. Twist the distributor back into the cylinder head after putting on a fresh O-ring, place it in the same position it had before, and make sure the distributor lugs match the grooves in the camshaft to stop you from installing it incorrectly. Check twice that the distributor and cylinder head match up correctly where the base mates to the head, and make sure the rotor points to the same spot as your previous mark. Re-install the hold-down bolt loosed, and put everything back in place by doing the reverse of your earlier steps, making sure timing is right before tightening these hold-down bolts well.
