not sure about the reverse switch but the oil pressure unit is right above your oil filter

Reverse light switch is in the NSS assy. There are many write ups on this online, HTH!!

ok well the nss still works because my jeep will only start in N and park so what else could it be causing my back up lights to not work

there are two copper contacts on a arm that moves inside the switch, they have small springs behind them to keep them pressed into the circuit part of the switch. One my jeep The lower one was gummed up and Stuck (reverse lights). The upper is part of the safety start circuit. Just because your jeep still starts doesnt mean that isnt your problem. 99% of the time it is. It is on the pass. side of the tranny drop it down enough to take it apart clean and repack with dielect grease. Be gently with the switch i broke mine the first time.

This is not entirely true, mine will only start in Park or Neutral.. but for the reverse lights sometimes they go on, other times if I want/need them on I have to move the shifter slightly to get them to go on.

That is what 98jeepjeep just told you, the switch either tends to get gummed up or worn out. I had the same problem and the neutral switch IS A SEPERATE CIRCUIT which means that it can still start and be a problem with the reverse contacts. It is a fairly common problem but the switch can usually be cleaned out and fresh grease put back in it to fix the problem in most cases. Also, the oil pressure switch is screwed into the block near the oil filter. Usually very easy to spot.

ok thanks guys ill try to get to checking that out some time today..

now with my oil pressure switch how can i check it to see if it is still good or if my gauge is bad

It's usually a bad sending unit. I've not heard of many gauges going out. The sending unit is about $20.00, so it's pretty cheap to replace. Here is the write up I used to R/R my NSS:

take the wire off the sender...Ground it out...if the guage goes up smooth and pegs out and holds...the guage is good. then you either have a bad sender or crappy oil pressure.

but my gauge is already maxed out

then your sender is probally junk

Excellent article, thanks! I think this is why I lost my back up lights. This sounds like an easy procedure. Do you have anything to add? I'm a little confused when they talk about the contacts, but don't show them in the pics. Is it pretty apparent? And I've got my concerns with the alignment/adjustment they talk about. Again, is it pretty obvious once you take it apart? Thanks!
