B4000 Stereo wiring.

Hey everybody,

I want to preface this with that I'm not a total novice and feel embarrassed to even be asking for help. I am intimately familiar with wiring harnesses, european wire codes, and installing stereos in all sorts of cars over many years.

But man, this 1994 B4000 extended cab is driving me nuts.

I cannot find even a relatively accurate wiring diagram for it, and no colors make sense for standard stereo wiring.

There's a large blue lined cluster that contains white with pink stripes, light purples, white with orange stripes, and a few thicker gauge wires like a blue (standard antenna usually), black with green stripe, black with yellow stripe, etc.

None of it makes sense. I've found the accessory and switched 12v wire because I can get the stereo to turn on (ungrounded even!). But can't figure out which are speaker wires, antenna, etc.

What is Mazda and Ford's deal and how the heck do I find a diagram for this?

Thanks for any guidance.

can't you take door panels off and trace/ping wires from speaker end to harness at the radio?
