I just finished some more extensive reworking of the gauge panel.
+ Ground off the excess plastic from the gauge console bucket to make room for the new parts
+ Rewired the turn signal indicator LEDs
+ Replaced the turn signal relay with one made specifically for LED turn signals
+ Wired in a dc-dc converter for the led segment display voltmeter
+ Made a mounting plate for the voltmeter and original speedometer face
I'll take more pictures of the work I did inside tomorrow, because right now I'm really tired of opening and closing the center console.
I might still have space to put the original speedometer back in.
