4.0 swap

I'm swapping in a 4.0 ohv out of a 1994 ranger into my 1997 2.3 ranger. I'm having trouble understanding what wires I need to hook up on the 4.0 harness to work with the '97's body harness. If someone has a diagram or something that's great, of not advice is good too. So far I have my engine...

Hey All- I'm hoping for a little guidance... My rig is a 1986 and I see plenty of articles on the 4.0 swap, I already have that in and have run fuel lines, new exhaust, etc. Now I'm working on wiring... I found the webpage on the dash swap (I thought that would be easier and look cleaner that...

Hey all, figured ive been here long enough, could be worth making a little build thread! Back in august 2015 i was perusing facebook marketplace (maybe it was Craigslist, i actually don't remember lol) and found this little clapped out ranger, said it runs and drives, just cant go past 45. and...

I am in the midst of swapping my 4.0 into my 85 bronco 2. Before pulling the engine, i had all lights and signals. After pulling the engine and engine harness there is no power to anything. Lights should be on an independent circuit, but nothing is working. Excuse my crude drawling but this is...

when i did the 4.0 swap i installed a 92 explorer engine harness and my truck is a 90 ranger so i left the dash harness in place. the connectors ended up being different and i tried a few things but nothing worked. as of the first time i ran my new motor, the tach did not work. i had oil...

Ok I’m new to the ranger station have read many write ups on the 4.0 swap but first time posting. Original Vehicle: 1992 Ford ranger STX 2.9 4x4 manual trans donor vehicle: 1994 Ford ranger XLT 4.0 4x4 manual trans I actually done a chassi swap left all harness intact with the motor and...

Here’s the engine and trans along with everything else that came with. I’m looking into a wiring harness but I’m having issues finding one, if anyone has access to one please let me know. Also dash and gauge cluster any recommendations on where I can get those?

Wiring Write Up for 2.9 to 4.0 Swap with Original First Gen Dash I also submitted this as a tech article Alright boys, a few months ago I finished wiring up my 4.0 swap and I promised myself that I would write the article that I wished I had at the time. There’s a lot of great articles on the...

Wiring Write Up for 2.9 to 4.0 Swap with Original First Gen Dash Alright boys, a few months ago I finished wiring up my 4.0 swap and I promised myself that I would write the article that I wished I had at the time. There’s a lot of great articles on the mechanical aspects of the swap, so this...

Howdy, I'm new on this forum, sorry if this has already been discussed on another thread. I have read up on the engine swaps other guys are doing but I haven't seen where anyone has done the exact swap I am thinking of doing so I wanted to reach out and see if anybody can tell me if this will...

89 B2 with 92 Exploder engine. When key is turned, the starter does not engage, and the check oil pressure light comes on. Could it be that the truck is completely miswired, or that the oil sensor is trashed? Help?

I have done some research and I have found that some 4.0 engines can blot straight up to a 1992 ranger 2.9. I am wondering if a 1999 explorer 4.0 will blot right on the tranny, and motor mounts?

I am in the midst of doing a 4.0 conversion from my 1992 ranger stx 4.0 4x4 5speed into my 1990 ranger xlt 2.9 2wd 5speed. No problems getting the engine in and hooked up and got it running but my instrument cluster doesn't work, the turn signal indicators and high beam indicator are alway...

Just curious if any one has done a swap on a 2002 or newer ranger with an existing 4.0 to a 5.0? I have a 2002 4.0 4x4 4:10 gearing 5 speed auto with torsion bars that has 240,000 miles. the timing chains are needing replaced and I can swap a remanned 4.0 with a 3year unlimited mile warranty for...

Alright, so I have an '89 Bronco II 2.9l with 235/75r15 tires, which really bog it down, and I'd like some more power. My friend recently rolled his 2000 explorer and is willing to sell it for me $300. The roof is trashed, but everything under is fine. I've heard of people putting 4.0s in BII's...

i need help.. i want to swap my 3.slow out for the 4.go. i have a 97 ranger. i need to know if a 4.0 from a 2005 explorer will just bold right in. motor mounts the same location? transmission mounts in the same location? drive shaft differences? i have looked all over the net and cant find any...

My 2000 Ranger XLT 4x4 currently has the 3.0L-V6 in it but I'm going to need to replace it soon (rings and compression issues and 200k+ miles), my question is this: should I just replace it with another 3.0 or upgrade to the 4.0? This is my daily driver and needs to be reliable. What do you guys...
