I have actually just done this on mine thanks to the help of a few on here and some pointing in the right direction, as either my alternator or voltage regulator had packed up altogether and the battery wasn't charging. Guess they're in different places on later cars as mine ('75) is, or rather was, in a completely different position. I used one of these to avoid the possibility of me messing up the wiring mods:

Very simple even for a spaz like me and worked a treat.
