Wiring Problems on EVO custom
Has any one wired up the coils on a custom evo setup. Anyone that did could be of some help andwould be appreciated. It has a EVO engine with three wires coming out of the bottom right side of the engine. I am wiring up 2 Donnie Smith type coils in the v pattern on the left side of the engine. My wire harness is a Ultima Wire harness. The wire harness has the positive coil connection. Now my question I also have a factory computer box for the EVO engine with about 9 wires on it. Do I need to hook it up and go with the pink to the coil - and use the computer box positive or do i just wire one of the wires coming out of the engine directly to the - terminal of the coil. and let the ultima box do everything thanks this really has me stumped

Pink does come off the coil the terminal opposite the hot side or the white wire side Is this 9 wire box a stock harley ign mode? does it have a 7 or8 prong plug on the end? Do you want to single firenthe coils or std dual fire?

RE: Wiring Problems on EVO custom
Sorry to take so long to get back with you but the way i work i get on the wiring very little.
I have a wiring diagram but i am wiring an untima wire harness to stock harley module to a set of dyna coils twi single tower ones and i can't seem to find a diagram that shows these three parts.
the module is a stock harley with a 8 prong plug with one of the prongs capped of so only 7 wires exit the connector.
here's what i have done so far white with black stripe from ultima harness {12 volts ignition} to the + side of both of the coils
pink from module to - side of the coils
white with black stripe from module to the + side of the coil
the rest of the wires hooked from module to either timing module or the voes switch per factory colors.
I get spark with the plugs out of the bike laying on the engine. not blue spark but almost more of a yellow spark put the plugs back in the engine and prime with it a little starting fluidnot even a bang.
any ideas. thanks again rwwintx
