Gauge wiring

[putnam00]

Ok so i have a problem. I did an lt1 engine swap on my 1971 Chevy c10. and at the time I had the non gauge cluster and now I have a gauge cluster from a 72 gmc. I have changed all the pins around for the blinkers, fuel gauge temp (but I need to find a sending unit that will work for the temp), but I can get the battery to work on the cluster. I have the fuse able link still but its not on the block its strait to the battery, and I don't have the external regulator anymore I am running the lt1 alternator. How do I make it to run the battery gauge?

Thank you

I still haven't had any luck getting the battery gauge to work I played with it and can get it to charge and decharge with the key off and turn the key on and do nothing. I have an adapter that connects 2 brown and a blue to the alternator on my lt1 and an aftermarket gauge shows a charge, but I would like to nix those gauges and use the factory gauge cluster

Ok, Found out I shouldn't run that high of an alternator on that gauge. I got an 80's gauge and with a little fab work I am going to put it where the factory gauge was suppose to be. just sticking it behind where its suppose to be and it looks like its suppose to be there
