I have a pop quiz for you guys. I have a 98 SR5 that came with 4.10's. I installed a TRD axle with the locker in it and now have the task of wiring everything. I got the ECU and engage switch with the axle and am now looking at my current wiring set up. The main wiring harness on mine is for ABS only.

I took the lower dash apart around the steering wheel and found two plugs, both with ten prongs and the black one fits the locker ECU but only has 4 wires attached and neither of them fit the RR DIFF LOCK switch. I will post pictures below and was hoping someone could identify the plugs and what they go to.

Do you guys think they are for some other option like a sunroof or something else? The location is directly to the left of the steering wheel behind the plastic where the RR DIFF LOCk switch should go...

I'm in the same boat as you. I just installed the elocker rear a few days ago and went to install the ECU and switch (knowing there was still more wiring to do, of course)

I looked at one writeup from someone that said they had the wires for the switch and ECU behind the dash (switch) and drivers kick panel (ecu) but did not have the wires going to the rear. I thought I would have the same amount of "prewiring" but like you, I only have the two connectors as you describe. Like you, the black one fits into the ECU, but neither fit the switch. I don't think they have anything to do with the elocker as the location for the elocker is supposed to be near the floor and the black connector wouldn't reach anyway. I'm not really sure what they are for. Maybe fog light switch? They are not for the sunroof because I have a sunroof and still have the 2 mystery connectors.

I am going to just use the wiring diagram that can be found here http://home.off-road.com/~kemanuel/elocker/locker_wiring.jpg (I know i've seen it other places too) The only probem I will have is trying to find a way to attach the wires to the terminals of the ECU and RR DIFF LOCK switch.

Hope this helps!

 

Install one of these and forget about it... simple set up.
