Ammeter to Voltmeter...who does it?
(Edit: yes like in the post above. You got it! No need to lengthen or cut anything, just add one wire with link. You can keep or the ammeter or not, it just won't read the battery charging. It probably will read the battery discharging at start. That's what mopartim observed. Probably 'cause its the shortest route to the main splice from the battery.)

Not quite. Now its back stock. Which IMO may be fine - everything you show looks pretty heavy duty and clean (except the crunchy fusible liunk)
