I was working on my mj for the first time in awhile today. I gutted the interior to clean out mud from the last offroad trip n to fix the leaky sunroof. The truck has been parked nose down on a small incline for a few months. I had a small oilly mess in the bed when it was parked. As soon as i pulled the carpet up i found some small wet oily spots on the back cab wall! Apparently the oil mess in the bed was running out the drains in the front of the bed onto the top of the frame rail and up against the back of the cab. The factory seam sealer must not be applied all that well cuz that is where the leaks are coming from. And the truck has been covered because i knew the sunroof leaked and did not want my new floors to rust. Now i guess the bed needs to come off and all the lod sealer removed and replaced. Yay!!!! This is a warning to everyone that is getting a wet floor and cannot figure out where it is coming from... Check the seams on the back wall!!!!!!!!!!!!!!!!!!!

I'm currently running this tb. The tre is replacable with a stock jeep tre. I have not had any issues with it and ive been using it for two years now.

The only part of the xj rear harness you will need are the plugs that plug into the dash harness and about a foot of wire... The same for the mj dash harness. You said that you had the wiring diagrams so as long as they are accurate, it shohld be fairly simple to put together. and you are right, because mine is from a ho it will be a little different than yours. I'm off work tomorrow and need to work on it anyways, so i will pull the jumper out And post the details. I can't promise any pics but ill try. And typing all this on the fone isnt too bad... Touchscreen and a fullkeyboard help. :)

I went thru this when i put everything from the dash forward from a 94 xj in my 88 mj. I made a pigtail just how u decribed so i did not need to cut either harness. If u have wiring diagrams and the old harness' to rob the needed conne tors from your set. You will also need to run a wire from the brake light switch to the turn signal switch. Mj's have combined brake and turn lights where as xj's have separate lights. All you do is run a wire from the. Brake light wire in the plug going to the rear to the body side of the plug for the turn swich. I'm typing this on my i fone so i can't post pics. If you really need me to i can pull the jumper harness and tell you wire by wire but that is gonna be alot on the fone. That said, i will do what i can to help out a fellow jeeper and especially a fellow mj addict.

Like i said above... Search on naxja or gojeeps site

I would not have suggested the taurus fan if it would not fit. Many people have been using these in xj's for years. Granted, its not a drop in relplacement, but they can be used. Early to mid 90's taurus' with the v6 came with the 2-speed fans. Search on naxja or visit gojeeps site for write-ups. The 2-speeds get wired like any other fan. There sre just two circuits to wire instead of just one. And the high speed needs an 80 amp relay. There is not an aftermarket fan that pulls near the same cfm as these fans. If this is something you look for on ebay make sure it is a stock replacement fan. Some of the cheap replacements are not two speed.

I went through something like this when i had my xj with a sbc. I used a three core brass and copper radiator From a bronco ll with a v6. On the road or idling it never went over 180-200 depending on outside air temp. Offroad however it would overheat in 15 minutes. Make sure all the airflow from the grill is going through the rad. Block off unneccesary holes in the rad support. You will also definately need to find a way to let hot air out of the Engine bay. Space the back of the hood up, install vents, or a scoop of some kind. And as far as the electric fan debate? You can't beAt the two speed fans from a ford taurus!

I run mud king tires. They are made by bfg but are only about 150 a tire for 35s. They ride decent and last for about 35,000 miles. That includes heavy offroad use. I ran procomps mts before these and didnt like the ride or wear. They are very noisy on the Road though.

if your looking for wiring diagrams check out great lakes xj site. he has multiple fsm ready to download. 95 is one as well as 88 i beleive. if those links don't work anymore i do have them on my pc.

any time man. this problem drove me bat$#!& for 2 weeks bfore chico told me how to fix it. of course the wiring diagrams i have now would have been very handy then! letme know if it works out for ya

tying the brake lights into the turn switch is the only way to stop the brake lights from overriding the turn signals. if you look at the comanche harness and a similar xj one you will c that the mj uses all ten pins and the xj only uses 9. being as you have the chrysler column I'm not sure how it would work. that column was never used in a mj or waggy. take a look at the plugs and count wire on both sides. if there is one extra coming out of the column that stops at the plug that should be what you need to tie the brake light wire into.

is there an extra wire that is not used maybe?

tie the brake light wire into the white wire in the turn signal switch plug. my brake light wire is white with a tan stripe. if you look at the plug for the turn switch you will see that it has ten wires coming out of the column and only 9 leading away from the column. i used a wire tap to hook mine up or you could try to add the pin to the plug.

i just left the renix pump in the tank and hooked that up. been working like that for over 6 months.

sorry bout no pics yesterday... broke the camera. if you call me later this afternoon i can give you the wire colors, etc. if you have any other questions feel free to call as i won't be anywhere near a pc. chipped spider gears in my 8.8 means spending the day regearing it and reinstalling it. yay! 456s!
