What are your intentions here? Are you thinking you want the locker lights to light with aftermarket lockers? If so it won't be easy since they're operated by the PCM. You'd have to cut the wiring and provide 5 volts to the correct cluster wire for each of the two locker lights. And trust me, you really don't want to try to duplicate what the factory's lawyers created with the whole senseless locker lock/unlocking sequence/logic.
No I don't want the lawyer-logic. What I want is for the "rear lock" indicator to light up when the Eaton elocker is engaged and go out when it is disengaged.
Someone posted in another thread that a jumper wire can be made to go from the switch to the back of the cluster which intrigued me, however upon some reasearch it appears it is not so simple.
The after market switch I have outputs 12V when engaged to control the relay but the sense signal into the cluster is floating when disengaged and pulled to ground when engaged according to the FSM wiring diagram. OK, no problem. I can build a tiny circuit board that converts the white wire 12V signal from the switch into the active low sense signal the cluster needs.
But then I found out about all of this logic, so my guess is that simply connecting the sense signal to ground will not turn on the indicator because it probably needs to interact with the factory axle lock switch first to even start looking for a sense signal.
Even if the sense signal is usable without having all of the logic I still have the following questions:
- do non-Rubicon clusters even have the rear lock lamp?
- the wiring is missing from my vehicle so I would need to add a pin to the cluster connector, but what pin? what connector part number? Are those even available? I don't want to spend $100 on this to buy a Rubicon dash harness
So I am thinking this is all not worth the hassle and uncertainty. While I would like it to work it probably won't work.
