came across this on ebay. ordered one myself and it fits perfectly. Just what you need if you don't/can't/won't solder. keeps it nice and factory 
fits 91 and up. price is not that cheap, but its not that expensive either... it does both front speakers on my 2000 Micra S. all connectors are insulated too.
