They work great, no clips to loose, easy to get undone and made better. I've used them all over the engine bay. Here's a link with some more info: La-Z-Link
FYI -- The older style injector connector isn't the same as those other connectors (see pix in link above). The plastic guide detent for the injectors is not on-center, while the FICD and IAC is on-center. One option is to Dremmel off the plastic tab on the FICD and IAC (voltage polarity isn't an issue) and then the Nissan style injector connectors will fit. Probably more work than you want to go thru???
