84 f150 stero problems

does anyone kno of a website that will show me a complete diagram of the stero wiring harness for my 84 f150 i got a wiring adapter kit from some fruit cake auto store down the street from me n the wiring harness was all messed up kept shorting the stero so i spent the 20 mins like i should have done in the first place and hardwired everything n saved 20 bucks, everything works right except when i turn on my head lights i lose my power to the stero n i blew a fuse the other day for the dash lights so i must have somthing backwards.
if someone could get a full diagram that would be great


THANKS,
Sean
