Bike..1994 FXDWG, 35,500, purchased in Dec.

I had to replace the voltage regulator and decided to also replace the ignition module, coil, and plug wires. Some here suggested a Sportster module ( in older posts ) for better performance. I bought a NOS 1994 1200 module off ebay thinking the connectors would be the same ( same year )...wrong..!

The question is: If I buy a 7 pin to 8 pin adapter off ebay, will the Sportster module work even though the wire colors are different..? The wire harness is 7 pin and the new module is 8 pin....

Thanks for the help....GREAT forum..!

 

I'm researching modules right now, the sportster has a 40 degree advance, I think it's too much for the evo. There's a few evos can use D F and P curve. They also aren't easy to find with only P curves readily available.

 

Have you got a schematic for the 94 sporty or module? I'm surprised the pinout is different, but if we have the schematics for both, I bet we can figure it out. BTW, an 87 Sportster ignition has 7 wires.

 

im not saying they are wrong but I wouldn't believe that would work very well. sportsters have a more aggressive curve and maximum advance at 45* that ok for a sporty. but not good for an evo if you set it to 35* your startup timing will be off. evo startup is 5* sportys are 3* so your startup will be off 12*. if you set it to 45* its most definitely going to ping.

 

Here's the stock curve info

 

No wiring diagram for the sporty, service and parts manuel for the WG.

 

. I have a 1997-1998 fxd manual if you want to confirm of it's the same for your year I can help you with they part. I still think you need a different module though. I think they switched in 1996 so my manual will have a different diagram than you need

 

I based my decision to buy the sporty module on threads I read here stating that the sporty module would have a better throttle response and higher rev limit due to the advance curve, ( " just put a used sporty module in as long as the connectors are the same " ). That was in response to people asking about using a Screaming Eagle module which would be more money.

 

What model number and curve are marked on the sporty module? I'm looking at these now for mine, you got me thinking. 32466-95A is what I come up with for later style but that's 8 pin different from yours right?


Also here's a link for you

I run a SE module with no rev limiter myself. I've heard people suggest the sporty module. Seems like you didn't get the "as long as the connectors are the same" part.

It looks like the MoCo changed the ignition pickup in '96. While it may be possible to wire the new one up to the old system, I'm going to suggest finding one that just plugs in. I think it will give you less trouble in the long run.

If you want to experiment, it looks like the VOES goes to pins 6 and 7, pin 1 is power (switched +12V), pin 4 is the coil negative, pins 2,3 and 5 go to the pickup, although I can't find what goes to what there. The colors may or may not be the same as the 7 pin version. Pin 8 is not connected.
