so finally got around to doing some more stuff this weekend. woke up early saturday morning and hit the junkyard... found a tilt column out of an 89 xj wagoneer and electric fan out of a 94 xj sport.
decided i was going to take the dash all the way out clean it, paint it, and fix my wiper motor so the wipers would park on the right side...
the column fit perfectly with two exceptions... the xj column has a collar on it to mount the base to the firewall, the yj has a 2 piece mount that hugs the column... a few minutes with a chisel and hammer and the collar was off... the other modification was the mount plate that supports the column... i had to drill 2 holes because the stock holes would not line up and were off a 1/2inch... other than that i reused the xj ignition switch, the reason for this is in an xj when you turn the key the rod pulls towards you, in a yj it pushes away from you... i didn't have to change any wiring, it all was the exact same... and since i snagged a tilt wheel coulmn that had a delay wiper switch, i also snagged the module on the xj dash... so now i have tilt wheel, and delay wipers and my wipers park on the right side now...
Built Not Bought #447, 1992 Jeep XJ Supercharged 4.7, 1988 Jeep YJ Auto 4.2L, 2008 Commander Limited HEMI, 1990 Jeep YJ 4.7L Fuel Injected AW4, 1981 Scrambler 304 Auto
so i got a wild hair up my a$$ and decided recently to do a lot of junkyard upgrades... such as rear view mirror with map lights which is awsome... also since i have a cherokee wiring harness on my stroker, i decided to grab a electric cherokee fan and install it as a puller since i already have a pusher... works awsomely... and plugs right in... another cool thing i found was a retractable underhood work light from a chevy pickup... works like a champ...
now a few days ago we went home to see some family and virginia... me being the true jeeper i am... decided i would pack a bag with a few tools and hit the junkyard saturday morning to see if i could find some goodies...
and I did !!!!
i found a lifted JK that had been wrecked...
i snagged the electric swaybar disconnect, the aftermarket wheel spacers, the subwoofer, the front seats, and the AEV snorkle... and i know your thinking wow this dude hit the mother load... well after the parts were off i was on my way... came across a grand cherokee with the 5.9L, went to snag the alternator, and guess what... it was still there but it didn't look stock... it was a 250amp Powermate by Wrangler... I walked out and only spent $25 all together!!!!!!
So i got home and decided I would go ahead and put the *direct* swap alternator in... ummmmm not so fast.... what i failed to realize is that since my motor originally started life in a 1996 cherokee, it would in fact not bolt right up and i needed to grind some metal off the block and alternator mount.... after a few hours, she's is in and I'm happy to say she works ! i can cut everything on in the truck and never see the needle fall once... here are some pictures for those of you who want the bigger alternator...
the stock alternator on the 4.0L is a teeny 90 amp... for those of us who don't have tons of cash... you can go to the junkyard and snatch a alternator out of
Great write-up. Tons of info. Im getting the parts and pieces needed to do a swap. old engine 88 YJ 4.2 new engine is a 4.0 HO. I have a 4.0 and AX-15 lined up just waiting to write the check. I have a questions tho?
How much re-wiring is involved?
Awesome information!!! I have been using this info almost exclusively for my conversion, and it has helped so much! I am a little confused with the wiring tho; i have most of the sensors hooked up and thats it. I don't know how to hook up the bulk head connectors. I guess my problem is that i have the harness in the engine bay, hooked up to sensors and what not, but i don't know how to get it tapped into my 1984 cj7 harness. the donor vehicle is a 94 cherokee HO.
Also, i have installed a VSS from a 91 cherokee and made an adaptor for the spedo cable, but the plug on the vss has 2 pins and the plug from the harness has 3. do you know anyway that i can work around this without buying hescos connector?
so i tried to get some of the wiring done today with little luck; does the red 4 gauge (i think) from the PDC go to the battery or does that get cut and then i run a wire to the battery from one of the bolts on the very end of the PDC? Also i read somewhere that the dark blue wire needs to be spliced into the cj harness, but my pdc doesnt have a dark blue wire. I am trying to get the jeep running before thursday so i can get to work, so im kinda rushing.
do you by any chance have a list of wires (color(s) ) and were the come from and where they go (i am awful at wiring :/)
what computer did you use?
I have ben using a 56027811 with on luck. I am tring to find a computer that will work. all the ones that ive sean are 56027--- but not the -----811 for a 94. So maby the last tree numbers do make a difernts
