digital to analog help.

[TougeRacing]

ahhhh I need help with this installation. well i got a sohc cluster off a fastback and the subharness for it to swap out the broken digital hud. However, after plugging the analog cluster with the new subharness, 2 fuses blew and its not working...anyone know what to do now? :bite: this isn't as easy i thought it would be.

btw its a 89' s13 coupe.
