SO for an E-body, you just add wires for each gauge fiorn the 5 volt side of the regulator??
Looks like and intersting upgrade!

No that's not the way I see it, the soldering of wires to the cluster is not how I would do it.
I would re-create the limiter plugs with wires with male spade ends to plug in like the original piece
soo there would be 1 power in 1 power out & I believe the 3rd terminal is a ground.
This would be easier with small piece of breadboard.
