1993 j30 radio wiring problems

[starion1991]

I have a 93 j30, I bought it without a radio installed in it, I recentley tried to install and aftermarket Cd player using a factory harness connector I got from walmart. But the factory harness is hacked up where it is supposed to plug in to the aftermarked one, I tried to match up the colors as best as I could but it dident work. No power to the radio and It is a bit confusing trying to figure out all the power wires. The speaker wires were not connected.

Just wondering if anyone has a wiring diagram for the stock j30 radio so I can just hook up the power ground and acc wire to the factory harness instead of going through the adaptor.

thanks guys

also, Dose the antana need to be connected for the radio to work in the j30's?
