89 Comanche No Running Lights/fuel Gauge ?

[Cabrarra]

Hello I'm stumped on my running lights and my fuel gauge and also battery is getting drained? when i pull the headlight switch it keeps blowing the 10 amp prkng fuse ? ive followed the wire from fuse block which is a red/blk tracer that runs into the harnes under dash where i do not know I'm told maybe the  ICM ? which ive already had to replace, I have posted his same problem in my jrwhite3230 account which i can't access so i created this one as for the  fuel gauge it is a tan wire  does anyone know where that goes to and what is the voltage on that? thanks for any reply ill try to post  pics of everything  too.
