    360 magnum O2 sensor install help

    Ok, checking to see how close I am. There are 2 green with white tracer wires that are spliced together. They are hot with the car running and the color matches the wire coming out of the 15 amp O 2 sensor spot in the PDC. This hooks to pin 1 from sensor? there are a couple black with white...

    360 magnum O2 sensor install help

    The O2 sensor I got has 2 black wires, a white, and a blue. If the diagram I found online is correct, the black wires are pins 1 & 2, the white is 3, and the blue is 4. Does that sound right? I would think the two black wires would be the grounds, but earlier it was stated that 2 & 3 were the...

    360 magnum O2 sensor install help

    I found the wires. They were cut off about 6” after they split from the main harness. I don’t remember cutting them off, but I guess I did. Hopefully everything is there for me to connect to. I do have another question. About a foot or so from the computer there are two wires taped together...

    360 magnum O2 sensor install help

    I need to check the harness again but I don’t remember any unused plugs. I cut all the wiring off from the power distribution block to the firewall. I was wondering if maybe the O2 sensor wiring was in that part of the harness and not in the part from the computer to the PDB

    360 magnum O2 sensor install help

    Thanks for the information. Can you send me a picture of or a link to the diagram you got the wiring info from? If it was in your head, I guess a pic of your brain will do. Everything you said made sense, I’m just not sure what wire S118 is. Also sense you seem to know wiring and you do a...

    360 magnum O2 sensor install help

    Thanks for the info. I haven’t bought an O2 sensor for it yet, but I’m thinking they are a 4 wire sensor. If I remember correctly 2 white, 1 black, 1 gray. Also I have come across this info (see pics) I’m thinking a 99 Dakota would have same pin out, maybe not. So if I’m understanding...

    360 magnum O2 sensor install help

    Here’s the scenario: 1999 360 magnum swapped into a 67 dart. Running stock efi, computer, and harness from computer to the fuse box. Summit headers with dual exhausts. Right now I don’t have any O2 sensors installed. I believe the donor truck only had on pre-cat O2 that was located just before...

    Help with stock EFI

    The car was ready for graduation, so my promise was kept. Of course he had to rattle the windows as he drove by the school afterward and he did a pretty nice burn out leaving. I was afraid his principal may have been upset by it, but we ran into her later and she laughed about it. Thanks to...

    360 Magnum with stock EFI engine codes

    Car seems to be running fine. He’s put about 50 miles on it since I cleared codes and the only codes it has now are transmission related. No o2 codes yet.

    360 Magnum with stock EFI engine codes

    My issue is I don’t recall a plug on the harness for the o2 sensor and I don’t know what wires to splice into to make it work.

    360 Magnum with stock EFI engine codes

    I’ve been doing a bunch of searching online and it seems like pre 2000’s possibly only have 1 pre and one post. The 2000’s have 4. I just don’t think I have a plug for it in the wiring harness. If I can’t find the plug I’ll hard wire it into the harness, if I can figure out what wires I need to...

    360 Magnum with stock EFI engine codes

    If I remember correctly the donor truck only had one pre cat O2 and it was just past where the two exhaust pipes came together. Maybe I’m wrong

    360 Magnum with stock EFI engine codes

    There are several reason. Many deal with lazy, lack of time, and lack of knowledge. I’m a long way away from calling it done. I’m going to work on putting an H pipe in and plan to put the first O2 sensor in it. My lack of knowledge kicks in by not knowing whether to us an o2 sensor from an...

    1993 42rh adjustment specs?

    I’m looking at adjusting the bands on my 42rh that is out of a 1993 dodge truck. I have looked several places online for the proper specs and the only constant number I am finding is to first torque them to 72 inch pounds before backing them off. From there the numbers are all over the place...

    Help with stock EFI

    Haven’t quite figured it out yet. They were off when he headed to school but were on when he got home. I don’t have the front 3 wire plug hooked up, just the one for OD and TC lock up. His slant six tranny only had a wire for neutral safety, nothing else.

    There are still a few little things to finish up, but he drove it to senior awards night. About a 25 mile round trip of highway driving and all went well.

    360 Magnum with stock EFI engine codes

    My post said I was asking for possible fixes. I’m well aware of why the codes are there. I’m also aware there are plenty of smart people on here that have done similar swaps and have probably come up with clever solutions. What I’m looking for is people to say “this is how I took care of this code”.

    360 Magnum with stock EFI engine codes

    I’ll double check connections, but pretty sure battery is good. I’m pretty sure the reason for the codes is the fact none of those things are hooked up. I don’t have O2 sensors, the transmission isn’t connected to the computer harness, I have the sensor that goes in the bottom of the battery...

    360 Magnum with stock EFI engine codes

    I’ve been able to do a few trips into town and around to shake down any issues with the car. I just hooked up the scanner and I have 8 codes. I expected to have some, and I’m not overly. Concerned about it, but if anyone has fixes for any of these, I’m all ears. First background for those who...

    Help with stock EFI

    Thanks for the info. Took the car for a couple shake down runs up and down our road. Doesn’t run too bad, shifts a little fun for 2nd to drive when shifting manually. Got a few noises to figure out, but thinking most are exhaust related. One thing that has popped up that I find odd is that the...

    Help with stock EFI

    I wish I was smarter at all the wiring. The way I have it set up I’m still using the old starter relay on the inner fender. It works fine that way, but I’m not finding any wires in the new fuse box that are hot with the key. They are either hot all the time or nothing. I would much rather be...

    Help with stock EFI

    Very close. I got the driveshaft from the shop last night. I still need to finish the transmission lines, straighten up some wiring, finish the exhaust, and redo the fuel tank. Old one developed a leak after putting it back in. Should be able to test drive Saturday. I’m anxious to see how good I...

    Magnum swap oil and water gauges with stock EFI.

    Curious what anyone running a magnum with stock Efi is using for aftermarket gauges. I’m thinking of putting a T on the oil pressure sending unit so I can hook up a pressure gauge. I’m afraid if I eliminate the electric one the computer might not like it. What’s my best and easiest option for...

    Air cleaner for magnum swap with factory EFI

    Curious what anyone else doing a swap like this has used for an air cleaner and not had to cut the hood. I working with a 67 dart and although I haven’t set the hood on yet, I think it the air cleaner is going to be too tall. I have a metal air cleaner from a 93 magnum and the recto plastic one...
