These are for the factory ignition coil? The reason I'm asking is I can't seem to match them up to the wiring diagram in my haynes book.

They are the correct colours for the renix, yup.

Someone needs to turn the boostu up on their soldering iron!

lol, not my soldering , this was a previous owners attempt.
I don't really need these anymore, cos I've made a whole new engine loom.. just need to get the ignition lights hooked up and it should be fine
