fi your car is a small block you can get the wiring you need from a Dodge truck in the wreckers & the dist & ign box as well , or you can buy a Chrome box from Mopar , it is basically a 1 wire install , the bluew wire to the ign box needs to be tiedinto the blue wire to the ballast resistor , , the black wire needs to go to the - coil terminal & you need to replace the dist & plug it into ther new wiring
the curve in the dist is the advance curve , this advances the timing a certian # of degrees as the rpm rises , this curve can be altered to get the engine to mmake more power
