Help I need a wiring diagram for a 2002 Toyota 4Runner Head unit.

I've searched through the forum and can't find what I need, I hoped it was close to some of the existing entries like other 2002 toyota's or close year 4 runners, but none of the wiring diagrams are correct for what I see in my truck.

The colors on the factory harness are as follows:

Grey w/Black stripe
Blue w/Black stripe
Black
Pink w/Blue stripe
(Light Green
Purple ) those two are bundled together
Brown
(White
Red
Green
Yellow
Black
Blue) those 6 are bundled together

and like an idiot I cut the stock harness off already so a wireing harness isn't going to help me

Also does anybody know why there is a standard antenna lead, and then another smaller lead that looks like an antenna lead? What do I need to do with that smaller lead on my new stereo?

THANKS IN ADVANCE

Here are the harnesses from Metra:
toyota 4runner - metra online. One of the wiring harnesses on that page will replace the one you cut off.

Thanks, but I guess my point was because I've already cut off the factory harness there is no point to me buying a harness and rewiring everything to that harness, I'm just going to wire directly to the new stereo's harness. Unfortunatly I need to know what all the wires are to do that. Does anybody know the wires?

Thanks

See if your wire harness colors are listed at www.installdr.com

No unfortunately I've been there already, everybody selling wiring harnesses or that has a wiring diagram thinks that all 1987 & forward Toyota's are the same, but they aren't. All the wiring diagrams have 2 plugs one 10 pin and one 6 pin. Well my 2002 4 Runner has one 20 pin plug. I thought I could just line up the colors but they don't match either. The closest thing I've been able to find that is correct for my truck is this link:

https://carstereohelp.net/wireharness_Toyota5.htm

which does indeed look correct for the back of the factory stereo and the 20 pin plug, but if that is correct, I don't understand it. Pin's 10 & 20 are not connected to any wire so I have no ground, I'm guessing 3&13 make up my power antenna, 2&12 make up my illumination. But where is the rest of the speaker connections? It only lists Front right +, front right -, rear right +, and rear left -, what about the missing 4 connections?

And I have no idea what beep or mute do (I'm assuming mute is for a cell phone).

Ahhhhh any help is greatly appreciated....

Thanks
