Alright, so my headliner only has one dome light above the front seats. I'm always needing more cargo light and I see a lot of other XJs with a rear cargo light. So I picked up a rear light at a junk yard. I was wondering, when I take the headliner down, will their be a harness I can just plug this light into or do I got too wire it into the front harness myself. Thanks

Also,,I picked up an ash tray light from the junkyard as well, plugged it in To the existing harness but it doesn't work. Is their a fuse for the ash tray light that I need to install since it didn't come with one from the factory, or is it just a burnt out bulb? Thanks again

I made a junk yard run for a new door on my 96 4 door xj,got a great deal for 30 bucks a pop. The issue i have is i cant find much on swapping 97+ doors on previous xj's so was wondering if any one has a link or insite on such a swap.I do know the strikers are different and of coarse the wiring so I was wondering if i can swap our the old door latches into the new doors and if any one has wiring diagrams for the doors? Or should i just find a 96 door and if so can i swap the full windows into the 96 door panels? Any help would be great.
I've dug through a bunch of places and can't find the exact answer to this (I think mostly because there's not usually a need to ask it).
What are the distances between:
bottom and top left
bottom and top right
top left and top right
...mounting points on the front window regulator (left or right) on a 4-door XJ?
Also, what's the glass travel from top to bottom?
I'm trying to see if the mechanism is a viable option for my car- it's an AMC/Jeep parts-bin special but nobody lists what the exact dimensions of the regulator are, and I'd rather not spend $50 on something that just plain won't work.
If the rail has the correct curvature I might be able to drill the spot-welds on the current brackets and re-attach them to correct the mount points and geometry.
Thanks

I am not a believer in Seafoam's engine product except in the original Marine context. Here in 2015 there's nothing Seafoam will really get you insofar as adding to the engine oil that a high detergent oil won't do (more safely), unless you are dealing with real problems.
As far as feeding Seafoam down through the intake, nothing really to say here other than "it makes a good smoke show".
BG makes a fantastic fuel system cleaner called 44K, and is well known to be actually effective.
Water in the intake is a great way to remove carbon.

The water clearly makes a difference on the pistons, and Seafoam seems to be negligible if anything in this context.
One big question first: I assume that was a gas motor? I had to keep the volume down, and I'm unfamiliar with Nissans.
As someone who has supported the use of Seafoam, these videos are very interesting to me. My understanding was, with Seafoam, that the idea was to loosen and burn deposits in the passageways that may constrict flow; not to burn carbon off the piston heads.
Would one of you gentlemen care to comment on that?

lol, gentlemen.
Yes, that was a gasoline MPFI.
Seafoam may have a mild solvent action, so it could work on the varnishes inside the fuel system - BUT it's a trillion times heavier than gasoline, potentially leaving crap behind as shown in the video. Adding it to the intake via brake booster line like 4.0L owners do doesn't even result in an even distribution of the stuff.
Not much point in adding it to the fuel when there are better products available that do the job right without leaving crap behind.

I'd take some more info on that, from what I've read(not a whole lot but a few hours worth), seafoam is the safest, most effective, hard to screw up treatment for fuel systems in general.

It depends on what we're talking about. If I recall correctly, when added to fuel, it acts like a stabilizer. It can help with issues relating to ethanol and varnish formation, such as what it's used for in the marine industry. That's a very different thing from a fuel injector cleaner.
