If theres only one plug on the back of your radio thats it...

"you wired the radio to the adapter" Is the adapter not just a plug on plug or what ...?

It also depends on what brand the radio is (Kenwood, JVC, Sony etc). You may need an adapter for that too, to fit the adapter you've already fitted.



p.s. does that make any sense? It's almost 1 am over here.

You should have this harness right here. The bigger plug has your front speaker wire and power and ground wires. The smaller plugg has your rear speaker wires. If you dont have any rear speakers (as some pickups did not) then there will only be the bigger plug that you need to hook up. In this case you will leave the purple and green wires of the radio harness un hooked along with the amp turn on and illumination wires you have already left off. Hope this makes sense.

Sounds like maybe a fuse problem? I would hook the factory radio back in and see if it works, if it doesnt start checking fuses. If the factory radio works then double check your wiring. Good luck.

Do you have a multimeter to check and verify that you have power to the radio? Also, does the radio have a fuse on the back that could have blown?

sounds to me like whoever took the stock radio out cut the factory connector off...thus making your harness/adapter that you bought pretty much useless. You will probably have to wire the radios harness directly to your factory wiring

Most radios need 3 wires.
Main power-this needs to be a keyed 12v source (on/off with the key)
Ground- Duh.
Memory- this is a constant 12v source that stores your radio presets/clock.

I got my truck in the same condition you did, just a bunch of hacked wires. I believe I made my own ground and just attatched it to the floor under the dash instead of tracking the real one down, but they're usually green or black. I found two constant hot wires under there, I think one was the cig lighter and it isn't enough to keep my radio presets once I start the truck (power is cut during starting), been meaning to try the other one for a couple months now but I never get around to it. Best way to go is just grab your test light and start finding what wire does what.
