Anyone with a factory e-locker, could you please take a look at the connector that plugs into your 4WD ECU? Since we're not prewired, I want to order that female connector for when I wire up our donor e-locker. Basically, I need the part number off the female connector that plugs into this (4WD ECU 89533-35070) It should be stamped on the connector:

I wouldn't waste my time trying to integrate the factory module. IMO that sounds like an unnecessary headache and it will still require modification if you want to engage in 4 hi. On both my Tacoma and 4Runner I used the factory switch and a DPDT relay. The diagram is linked below. The only thing different about my installs is I provided power to the factory DIFF LOCK bulb in the dash via a small gauge wire sandwiched on the contacts.

BTW I am from Ames...small world!

Believe me, I've studied nearly every thread regarding e-locker wiring, but I want to stay as close to stock as possible. Just my preference. I think I found what I'm looking for at newunitedracetech.com. Thanks for your input!

Nice find on the connector website. I have it saved for future reference should I need it.

Don't get me wrong I really appreciate your attention to detail but you make me feel like my OCD condition is almost non-existent in comparison. As long as you are enjoying yourself more power to ya. I have 3 of those modules in my garage right now and 2 out of the 3 have the plug with about a 6" pigtail of wires. I also have 2 switches. I would offer to sell them but I am not sure they would be good enough for you. In all seriousness and curiosity how far are you going to go in replicating the factory look?
-Same color scheme for all of the wires?
-Removing the tape on the factory harness to include the additional wires then tape it back up?
Also, you will need some additional connectors,bulb and bulb base for behind the dash to use the factory diff lock light.

Seeing a write-up on this would be impressive!

How about giving me the part number on the plug, like my OP asks?
