Graham, solder the wire, also there are actually four manuals for all Harleys. First is the owners manual, second is the repair manual, third is the parts manual, and lastly is the Wiring Diagrams and Electrical troubleshooting Guide. These usually cover more than one year and are for domestic and international. They are very usefull as not only do they have the wiring diagrams, but they also have some very useful troubleshooting matrix's. The part number for my 95 , perhaps you could use this number to chase one down is 99948-96. Harley likes to keep this manual "Super Secret", because it does make electrical problems pretty simple. Hope this helps.

Taking a close look at the connector to the neutral switch I gave up thoughts of trying to solder it, but took a punch to it and tightened up the rivet, then refitted it with some protective goo. It was a bit late to start the engine so I will check things over tomorrow.

For example we used the matrix to find the problem with a customers radio on a '91 FLHTCU even though the book was for a '95-''96. It had no volume, after going through the troubleshooting guide, we found out the push-to-talk button on the CB was stuck in.Hope this helps.

John,
I found a list of those and they were published as #99948-nn from 1990 onwards, entitled 'Wiring Diagrams & Electrical Troubleshooting Guide': 1988-90, 1992, 1994, 1996, 1997, 1998. Perhaps after that they published the separate electrical manual? I do wonder how they may differ from the electrical stuff in my 1987-1990 service manual! They cost $56 each, according to Chicago H-D.
I've rebuilt the bike to road-going condition now and my neutral light still winks, as before! Can't say I followed every suggestion, but I feel better for tinkering. I've done rudementary charging checks and at 1,000rpm-ish tick-over, the battery is getting over 14volts, with headlight and passing lamps, around 13volts with fogs turned on as well. That puts my mind at rest.
I would prefer to fix the darned thing, but I have to get the bike and so much other stuff ready, with just two weeks before we set off to Ljubljana.

GR, they go into a lot more detail, the diagrams are larger plus there is a very detailed decision making matrix for trouble shooting and cover all the bikes for those years. I think they are well worth the money for the average/above average Harley owner.

Lynn,
You will have to get the -90 version, it should have all the info you need for your '89.
