3.9 vs. 4.2 Oil Pan - Low Oil Level Sensor

[rwhitmo04]

I'm in the process of wiring up the 4.2 that went into my '89 RRC. I've discovered that the 4.2 oil pan doesn't have a socket for the "Low Oil Level Sensor". If it makes a difference, the 4.2 was a serp, and the 3.9 was a v-belt.

First question: does the 3.9 oil pan work on the 4.2? If so, then I won't have to worry about omitting the sensor altogether.

Second question: did the trucks that came without the sensor sockets in the pan simply not have the feature, or is there another provision for the sensor somewhere else? From this link on rangerovers.net, it appears that it should be pretty straight forward to disable the feature should I have to stick with the 4.2 pan:

I know there's plenty of engine swap threads out there, but I wasn't able to find any info on the subject.

the pans swap with out issues but of you don't want to do the swap just ommit... later trucks just did away with the feature...
from experience, by the time the low oil light comes on you have heard the tapping of the engine way before.

Thanks for the info. I'll probably just omit the feature - I'd rather not have to drop the pan again.

I tore that thing off years ago, sometimes the light flashes sometimes it doesn't.
