Will do. The factory tweeters are wired in parallel with the front door speakers, unless I missed a recent factory system. I think the four wires are for a connector that "continues" the wiring to the door speakers.

I already posted the audio system wiring diagrams for the '01-'04 models. Although the systems on the '05-'07 models have more features, some of the wiring (including the tweeters) is the same. viewtopic.php?f=25&t=903

I'll get the '05-'07 diagrams up today or tomorrow.

Thanks for the heads-up!

I'm looking at the diagrams now. The factory tweeters for '05-'07 models do have a four-pin connector that appears to contain a crossover and connections to the door speaker.

Ford sells the 4-pin factory connector that plugs into the tweeter. WPT-293 is the part number.

I'll have the connector pinout in a minute.

No problem. Here's the pinout for the C513 (left door) and C613 (right door) tweeter connectors. The WPT-293 Ford accessory connector (the same connector included in the factory wiring) is around $30 per connector, with around a foot of wire on each pin. You could just solder the wires if you don't want to shell out that much cash for two connectors.

The wiring diagrams and connectors for 2005-2007 audio systems are here: viewtopic.php?f=26&t=910

These are the connector faces, so the terminals on the tweeters are backwards. If you could post a picture of one of the tweeters, I could identify each terminal for you.

You're welcome... and thanks!

Glad to help!
