Gauges not working

Well, I ended up pulling the dash panel out. Several if the pins were loose. I soldered them and they are not lose now. I had mentioned that i put the solid state voltage limiter in. I i know when i had it hooked up i had 12 volts in and 5 out. I have the voltage limiter in the gas gauge. I just cut it out and bolted up the solid state voltage limiter. 'You seem to have had some experience with this. Do you have any tips?
Thanks
Steve
