Chris' '90 Toyota Celica All-Trac Turbo (aka "The Shuttle")
Electrical System Mods - Interior PDU
Updated: September 25, 2017

Here’s a look at the new power distribution unit (PDU) that will provide power to the various non-standard accessories, such as aftermarket Greddy and Autometer gauges, Autometer Tach and shift light, IC temp gauges, Autronic SMC, stereo, boost controller, etc. This PDU provides both constant and ignition-switched power, as necessary, through the two different fuse blocks seen in the photos.  +12 vdc power is supplied to each fuse block via the two individual 8 ga. cables, and a 70 amp relay controls ignition-switched power.

I have also developed various pigtails for things like grounds, tach signal, and illumination control to the gauges and other aftermarket accessories.  I think it's really looking good.
