unilite ? electronic breakerless conversion kit for mallory point distributors note: this product is legal in california only for racing vehicles which may never be operated upon a highway. installation instructions form 1466 (rev. d) 10/03 applications part no. 558 mallory 8 cylinder point distributors (automotive and marine) which use a standard stack cap (part no. 209 or 209d) part no. 559 mallory 8 cylinder point distributors (automotive and marine) which use a flat cap (part no. 221 or 221b) part no. 560 mallory 6 cylinder point distributors (automotive and marine) which use a standard stack cap (part no. 270 or 270b) part no. 561 mallory 6 cylinder point distributors (automotive and marine) which use a mini bowl cap (part no. 226 or 226b) part no. 562 mallory 4 cylinder point distributors (automotive and marine) which use a standard stack cap (part no. 271 or 271b) part no. 563 mallory 4 cylinder point distributors (automotive and marine) which use a mini bowl cap (part no. 225 or 225b) parts include in this kit: 1 unilite ? plate assembly 1 wire harness 1 rotor/shutter wheel assembly (pn 559 contains 2 rotor/shutter wheel assemblies) 1 wire connector 1 grommet, 3-hole (marine approved) 2 pins, aluminum 1 thrust button warning you must install the unilite ? conversion kit exactly as shown in these instructions. after the kit is installed and before you start the engine check all wiring again. mis-wiring will cause the unilite ? ignition to fail immediately. installation step 1 remove the cap and rotor, then remove the con- denser. remove the plastic insulators (see figure 1). step 2 loosen the 2 nuts that hold the cap clips/brackets in place (see figure 1). note: to loosen the nuts on a marine distributor, the aluminum pins in the brackets may need to be cut in two and removed. replacement pins are provided. step 3 remove the point plate assembly by lifting it out of the housing (see figure 1). mallory ignition www.mrgasket.com 1 important all kits listed below must be used with an ignition ballast resistor (or loom resistance wire) to prevent module failure. if your vehicle is not equipped with a ballast resistor or loom resistance wire, mallory ballast resistor (part no. 700) may be used. these kits do not work with vacuum advance distributors. figure 1 condenser insulators point plate cap clip nuts
step 4 use a 2-arm or 3-arm puller and the thrust button (provided) to remove the cam from the rotor sleeve (see figure 2). warning: do not try to remove the cam by prying on it with a screwdriver(s). this will damage the advance assembly. step 5 install the unilite ? plate assembly into the housing. make sure that the cut-out in the plate is directly below the hole in the housing where the wires will exit (see figure 3). step 6 tighten the two nuts that hold the cap clips/brackets in place. this also secures the unilite ? plate. step 7 marine distributors only replace the cap clips using the new aluminum pins provided. step 8 install the wire grommet. lubricate the wires with light oil. run the wires through the grommet and out of the distributor housing (see figure 3). step 9 install the connector onto the wires. be sure the wires are in the correct positions (see figure 4). step 10 install the rotor/shutter wheel assembly. make sure that the rotor is fully seated and that it does not rub the module wires. replace the cap. step 11 if you removed the distributor to install the unilite ? conversion kit, reinstall the distributor in the engine. step 12 connect the wire harness to the connector. connect the 3 wires to the correct locations, as shown in figures 5 and 6. step 13 set the ignition timing. start the engine and recheck timing. mallory technical support (216)688-8300 www.mrgasket.com 2 figure 2 figure 3 figure 4 puller thrust button remove button after cam has been removed cam grommet unilite? plate assembly connector red brown green female connector index rib distributor wire harness red brown green t
