Voltage Indicator difference from 88 to 91?
I swapped out my 88 TBI to a 91 TPI. The 88 uses the "L" terminal from the alternator to send a signal to the voltage indicator in the instrument panel. The 91 does not make use of the "L" terminal from the alternator. Instead the diagram shows a ground on one side and hot feed from the gages fuse on the other side. Do I just need to tap into a hot feed on one side and a ground on the other? Wasnt sure it was this simple if the 88 used a feed from the alernator. Sorry so lengthy. Just wanted to explain everything.
Thanks,

Pretty much. Doesn't really matter where it comes from.
