MAD ammeter bypass question

I started looking at the headlight relays. I see people have used the Toyota headlight assembly kit - 2 headlights and a harness with relays....$31 Cdn! The parts guy at Toyota even told me what a steal of a deal it was. I ordered one so we'll see what it looks like:

Genuine Toyota headlight kit made in Japan that works with the FJ60 and BJ60 Toyota Land Cruisers. This kit allows you to replace your sealed beam headlights with halogen headlights with replaceable bulbs. Kit includes:

- Pair of Headlamp Glass Lens
- With Bulbs
- Wiring Harness
- Zip Ties
- Instructions

OEM; Made in Japan.
If those instructions tell you to connect the relay secondary power to the battery, disregard that and be sure to connect the relay secondary power feed to the alternator or somewhere on the alternator side of the ammeter.
