If the crank has not been turned from when it was dot to dot when built, clock the inter gear/shaft whereever it needs to be so it locates the rotor rearward and slightly to the DR side and place the #6 plug wire there & route them on around CW. This maintains the OE plug wire diagram & lets the wires nestle neatly & be as short as possible. turn the crank slightly back so the timing marks are at 10BTDC (mild cam) and 15 (wild cam) and the vac can is located on the pass side and has room to be turned and the magnet is dead even w the reluctor tooth that locates the rotor under #6 & lightly snug the housing & you're set. If the timing marks are at TDC #1 compression (firing) (6 & 12 o'clock on the dots), then clock the rotor forward and slightly to the pass side & locate #1 plug wire there and same as before back up the crank slightly to 10 or 15 BTDC. and route the wires on around clockwise 1-8-4-3-6-5-7-2. Keep in mind you want to turn the eng by hand as little as possible to keep from wiping the lube off of the lobes. initially locating the intergear slot parallel or the front edge slightly to the dr side will get you close then go from there
