System Sentry Sensor Location Dilemma

[eaglescout526]

I know this is XJ but honestly, I can barely trust facebook groups to not give me 30 likes and zero advice. And I dont want to join an XJ forum when I know all of you guys are the best and can give a good answer or an opinion on stuff.

 

So on the D30 AMC located its oil sensor on the left side of the pumpkin if you are looking at the pumpkin from behind. This one surprises me, rather AMC just make one axle and issue a plug kit for each on that doesnt have the system sentry, they made two. One with the sensor hole and one without. Same goes with the D35. 

 

My 30 does not have the plug nor hole, I want to add it to the 30, but drilling on the side where it goes will be tough as I would either have to cut the LCA bracket, I see that as a BIG no no. Or I drill a hole through both LCA brackets and get to the spot where the sensor goes but I would need to get the right size drill bit in an extreme length.

 

Course another option I have is to drill a hole in the front of the D30 cover and put it there, but from the looks of everything, it looks rather small and compact to where that also could be a challenge.

 

What would you guys do?

I'd go an aftermarket cover and drill the cover. They are easier to replace and find

Also what exactly does it do, is it looking for level or temp?

That’s an idea! Maybe an armored thicker one would allow for the original cover to get trashed with the sensor in place.

It looks for level based on the continuity used by the fluid. The oil completes the circuit and let’s the module know it’s full. Once there’s no fluid to complete the circuit, it shows it as empty.

Need for precise and accurate drilling here for the exact location of the sensor. I think engine oil level was 1qt low, light ON. Don't know what rear axle level SPEC is.

It’s probably half a quart for both axles given the locations as where they should be.

I didn't know these sensors were a thing. Are they still available? Part number?

Theyre for a very old set up I’m putting in my XJ. 84-85 only were the model years it was available. I know they can be adapted to use on an MJ if you found the whole thing. 
 

So this isn’t something that will plug n play in an MJ. 
 

What I have is the last NOS in the world. There’s some number on it but it’s not the AMC number which I don’t have at the moment.
