Hi, I bought a 99 TL recently and need some help finding correct diagrams for the wires. They were cut by mistake when putting in an aftermarket receiver and I can't find any wire color diagrams that match up with my car. Different websites are giving me completely different answers, and some of the websites Have colors that my car doesn't even have. I just hope I won't have to use a Bluetooth speaker until I get a new ride. Anything helps. Thank you!

 

It should be something like this. You'll be mainly looking at the 20-pin connector.

You should grab a new proper 99 TL plug from the junkyard, solder that on properly, and then use an adapter to solder to your aftermarket stereo next time that way when it's time to swap out for an upgrade you can just unplug it instead of dealing with this mess again.
