Piaggio Xevo 125 CDI install

[newboy]

Hi

Blew CDI on Piaggio Xevo 125. (SAE J590B) charging bike battery from car (pos, neg mixed up)
Purchased a new molassi by-pass CDI Part No (5512341) suitable for Piaggio Xevo 125 model above
to by-pass the immobiliser.

Turns out the blown CDI unit on the scoot is indeed an original piaggo (SAE J590B) but suitalble for the models below because
the connections on the CDI were different to the replacement Malossi I bought.
GILERA RUNNER VX 125 4T
PIAGGIO VESPA LX 125 4T
MALAGUTI MADISON 3 125 4T
PIAGGIO FLY 150 4T
PIAGGIO LIBERTY 150 4T
DERBI BOULEVARD 150 4T
DERBI SONAR 150 4T

Bought the scoot in 2012, it was a 2010 model. It came with everything and paperwok but no mention of work carried
out for a new CDI, but I can only guess that it may have been changed. Maybe the last owner had a problem and bought
the part on the nunbers off his origial CDI unit ((SAE J590B) which by the way isn't a specific part number for bike model!
Also it was situated behind the windshield, a mechanic said it'd be by the right foot.
Maybe factory fitted wrong! as the loom looks pro done?


Options
Install my newly purchased Molassi by-pass CDI suitable for Xevo 125 & buy new wiring/connectors loom to suit.(if possible?)
Depending on the connection at the other end of the loom. If indeed it's plugged into a same port when I find out where it is?
or
Sell my newly purchased Malossi by-pass CDI at a loss & buy a Malossi CDI compatble for piaggio fly 125 or other 125 model
with the same connections ports to fit my connector blocks?
or
change just the connector block to the right sized 8 pin, rewire and isolate 4 remaing unused cables...(If indeed are unused)

If anyone could help us out with advice or knows any auto sparks to ask I'd very much appreciate it.


Thanks for reading.

I got a good response stated here below...

"CM078311 is the correct part number for an Xevo125 ignition module which is the number on the label on your photo. This is the correct and original item for the bike and has not been modified.
This part has no cross reference to any other bike on either Suttons or Fowlers websites, so is probably unique to the Xevo.
If this is correct then my guess is the Malossi device is not suitable for your particular bike. You cannot simply assume just because the motor is the same that all the bikes electricals will be especially considering yours is fuel injected and the ones you list have carburettors.
Even if this is incorrect there is no way to determine which wires are not required without knowing the internal circuit on the Malossi and the original box, neither of which are available.
If it is able to be made compatible, then it really should be supplied with a conversion cable.

Are you sure you have blown the unit, as cross polarity charging has been done before and only blown the master fuse?"

I completely ignored that code he stated as I was blindly looking for a 14 pin Piaggio CDI with part number SAE J...

Anyhow I know need to find out how to test the CDI and other parts before I bite the bullet and have a pro repair if I can fix it easily!
