So I pulled the interior out of an 04(ish) qx4 to give my 97 qx4 an update. so far things are bolting into place but there are some hiccups when it comes to wiring. im stuck on the master window controller, which has a second plug. I can't dig up the harness pinouts anywhere to see what has to happen to use the newer controller. does anyone have pinouts for a 97 qx4 and a.... 2002 (give or take) qx4?

Hooboy, I'm pretty sure the '04 switch is completely incompatible with your setup. The '04 switch will be set up to communicate with the BCM and passenger side switch on a bit-bang serial line, the '97 switch is "old school" with direct switching from the master switch to the slaves. When you say "pulled", I presume you didn't change the window motors or anything like that. The switch wiring is drastically different, so unless you want to fabricate an entire cross-vehicle harness, your best bet is to try to modify the '04 bezels to accept the '97 switches, modify the '97 bezels to fit in the '04 holes, or just fabricate new hybrid bezels.

Yep. '02 and '03 QX4 have a totally different schematic than the '97. Infiniti didn't make a '04 QX4. Here are the power window schematics. '97 starting on page EL-171 >>> https://www.nicoclub.com/service-manual ... 7%2Fel.pdf '03 starting on page EL-380 >>> https://www.nicoclub.com/service-manual ... 3%2FEL.pdf

Notice the line on the '03 labeled "Communication I/F" going between the switches and to the SEC. The SEC was the BCM's prehistoric ancestor. That line is a serial bit-bang, much like the old K-line predating CAN.

So I did modify the housings to fit the old switch... Way easier than sorting out the electrics... Same with heater, cluster, and some other stuff. - huge improvement on the interior so far. I'm picking away at it slowly, but it's turning out nice so far... I'll try to post a few pics.

Is there any chance I can wire the analog clock in by tapping into some existing wires? Would it need much more than constant power like the "security" stuff or stereo memory or something?

Then opened the window And door lock ones up a bit. Worked out fine- Way easier than sorting out the electrics which sounds impossible or at least way over my head:-P ... Same with heater, dash cluster, and some other stuff. - huge improvement on the interior so far. I'm picking away at it slowly, but it's turning out nice so far... I'll try to post a few pics.

Check out the '03 clock schematic on page EL-186. https://www.nicoclub.com/service-manual ... 3%2FEL.pdf It looks very straight forward. Constant power, as you said, on one leg and power to the clock's light, on the second leg, only when your dashboard lights are on.

If that is too much of a hassle, cover up the clock with a cell phone holder. That's what I did on mine because it is an ideal position for a cell phone, I already have a clock displayed on my audio head unit, and I think those OEM clocks look a bit janky. ;)
