Need help perfecting the budget build hemi swap

So here we go again. I swear that the first time I started this car, it had no instrument clucter lighting, but somebody told me, " That mopar lite the cluster so poorly that in the daylight it's not all that percievable." and the speedometer was stuck at 25 mph, I had one gauge that worked - the fuel level. Well, the speedometer fix itself, the dash lighting is now working, and today the tempeture gauge decided to join the band. I think I own Christine. Wacky !
