One more 2wd 98 coil spring 5.0 swap.

As long as you use the cooresponding shroud with the radiator, you'll be good. Figured I'd save you some time since I've been through this a few times already....

Thanks again. I always like to be sure before I get to far ahead. After comparing notes with you I think everything will be good.

I just noticed post #327. Post up pics of the plugs you're having problems identifying. Also, right now on the trac I'm doing the V8 swap on, I have a code I'm working on (1309), the CMP & CKT timing is off. Make absolutely sure your CMP is dead on for timing, yours looks a little off. If you have the cam syncronizer alignment tool, make sure to use it...

Give me a bit and I will dig up a photo or two of the plugs. I have not yet set my cam timing but planned to get the tool and set it prior to initial start up. That is still a little while down the road.

One is going to be the 12 pin plug that goes to alternator/ac pressure switch, the other 12 pin plug goes on the fenderwell behind the battery...

I have both EVTM's and can look it up but thought I might hit you up for a photo if you got one showing the two connections.

I dont have one in my library, but can post it tomorrow by noon...

Thank you. I don't want to sound lazy. I can look it up and just pulled the books a few minutes ago. But it would be nice to have a second opinion as I am a bit new to the wiring and I am always second guessing myself.

 

[Lil-Pony]

Its good to second guess your self. Make sure you understand how the ecm controls relays. Weather its by grounding the relay or supplying power to a already grounded relay. Made that mistake on my 2.8 chevy tbi ignition swap on my b2

Near as I can tell they are both 12 pin connectors as you describe, circuit 179F and 184F. At least that is what I think. The problem is I don't seem to have the two plugs for these two connectors. Is it possible I am missing a small part of the harness? Also I can not seem to identify from the EVTM what these two circuits control. From what you posted we know one is the Alternator/AC pressure switch. What about the other one?

The 98 Ranger C184 is similar to 99~01 Explorer C125. Each of these connect to a small engine harness that goes to the A/C compressor clutch, A/C high pressure switch, starter, etc. This harness is different for Ranger or 5.0 Explorer.

The Explorer connector may have 2 additional wires for sensors related to the Message Center (trip computer that was not available on the Ranger).

Also, the 99~01 5.0 Explorer oil pressure switch wire goes through this connector but the 98 Ranger's is routed through the 42-pin into the main engine harness.

The Ranger C179 is for 4WABS (if equipped), similar to Explorer C140.

I was hoping you might drop in and lend a hand. I think I may be missing the small harness for the A/C compressor clutch and the A/C high pressure switch, or at least part of that harness to include those connections. I used the 2001 5.0L Mountaineer Engine Harness and Battery/Starter Harness.

Here is a photo of a cropped pigtail that runs off the alternator portion of the harness near the AC compressor location. I am not sure what this would have included other than ac connections. This is from the salvage harness that came with the salvage 2001 Mountaineer 5.0L I purchased.



Here is a photo of the 1999 Ranger 3.0L Starter/Alternator harness I saved from disassembly. It includes one of the male 12 pin connectors discussed in your previous post. I installed the 2001 5.0L Mountaineer harness to replace the one pictured here.



Here are two better photos of the 12 pin connectors in question located on the truck.





The first runs directly off the positive side of the battery cable/harness (2001 Mountaineer 5.0L harness).



The second one runs directly off the harness that includes the 42 pin connector on the chassis side (1999 Ranger 3.0L Harness).



Thoughts?

Questions:

The Battery Harness I removed from the 3.0L Ranger had a male 12 pin connector. The Battery Harness I installed from the 5.0L Mountaineer has a female 12 pin connector. Is it possible these connectors are for the same circuit? I am wondering if the two female 12 pin connectors remaining on the truck should be “connected”. I am going to pull the EVTM’s for both and start reading but once again I would feel better with a second opinion.

Are you sure about c125? I show it as c139 in the Explorer EVTM, same as Ranger c184. However, I am new to this and I am not 100% sure of my findings.

The heavy gauge Y/LTB wire is your starter solenoid wire. The R/Y and BK/W are the AC high pressure switch wires (vehicle side) and will need to be removed from the engine harness and installed in the fenderwell harness, along side the driverside of the radiator, to the new location of the high pressure switch. The remaining grey (GY/BK or GY/W, cant remember off the top of my head) and black wires are for the AC compressor clutch, which go to the 12 pin plug....

Here are two better photos of the 12 pin connectors in question located on the truck.

The one on the right is the Ranger C184 and should have all you need except the DG/WH to the oil pressure sending switch. Easy enough to add or route through the main engine harness.

The one on the left looks like the 5.0 Explorer C125 except I don't see a RD/YE. Somewhere in my foggy memory, I seem to remember that the 01 5.0's had a couple of wire differences compared to the 99~00 but I don't have a 01 Wiring Manual to confirm that.

The Battery Harness I removed from the 3.0L Ranger had a male 12 pin connector. The Battery Harness I installed from the 5.0L Mountaineer has a female 12 pin connector. Is it possible these connectors are for the same circuit? I am wondering if the two female 12 pin connectors remaining on the truck should be “connected”. I am going to pull the EVTM’s for both and start reading but once again I would feel better with a second opinion.

I have seen this before and I believe that I had to change connector shells on mine (99 Ex in 2003 Ranger). So, yes, possible.

Are you sure about c125? I show it as c139 in the Explorer EVTM, same as Ranger c184. However, I am new to this and I am not 100% sure of my findings.

99~01 5.0 Ex are ALMOST entirely identical. Both my 99 and 2000 Ex Wiring Manuals show it as C125. It is possible that it got a different ID in 2001 but again I don't have that manual so I can't confirm or deny. I do remember that they redid a wire here and there to accommodate an OBDII change.
