hi, if you have the chrysler auto, it will have the same electronic solenoid as in the wg with the v8. I use a wk /wh in my wjs. The white solenoid . The reversing light switch is part of the solenoid and it goes out regularly. Got one of my wj'
s through roadworthy as the tester could not get the reversing lights to work after changing globes and felt guilty having charged me to replace globes.
If you buy, rockauto is not the place but ebay usa and only buy genuine.
I update all my wjs with the later white solenoid but you wont need the detent plate as it is for converting the earlier black solenoids to the later white.
Can be done if you are servicing the auto, just drop the valve body and it sits on top of it and pushes through the case.
hope this helps,
Peter
