1998 fld120 freightliner semi truck 975074

Mechanic's Assistant: Are you fixing this yourself? What have you tried so far?

Ye sand no I am putting an engine form this truck in a tractor. I need a certain section of the wire diagram to figure out 4 wires

Mechanic's Assistant: Anything else you want the equipment mechanic to know before I connect you?

I am working on the section of the wiring that has to do with the engine fan switch. I need to know where all 4 wires go form that switch. I have never done this before ... how does it work and how long does it take? Cost?

Dan,
I have never done this before. I did not know that the answers took so much time to get. While I waited I read some info on the internet that lead me to the specific answer I needed. However I could still use some help. I am putting s series 60 Detroit 06r0427030 from a 1998 fld120 Freightliner semi tractor serial # 975074 into a Stiger farm tractor. I kept all the wiring from the truck and am installing that wiring into the tractor as it applies to the computer systems of the truck. I will end up with one wiring system from the farm tractor to run lights, ac, heater fan etc. The truck system will run computers, engin gages, control modual and display center. In the process I am illiminating some things like Cruse control, Jake brake and s number of switches that I don't need. There will be a number of those illiminations that might trip me up like clutch and brake switches perhaps needing to be jumpered or low air sensors etc. I have a book with the wiring diagrams for the farm tractor. I have a scematic from Detroit of their systems but I don't have a wiring diagram from Freightliner of the Detroit specific wiring in the cab ( with wire numbers) to help me double check my re-instalation and to help me solve mysteries like the fan clutch switch I originally wrote about.( I forgot that engin fans are on with an absence of power instead of a presence of power)�� also in the future I will need a diagram to solve breakdowns and other stuff that pops up. If you can get me a Freightliner (Detroit series60 specific) wiring diagram that would be great. Or perhaps a part number to order one or website to download one that doesn't require a perscription or some affordable way to get one. ( I do have an oversymplified diagram from the sleeper in the truck- covers basic important stuff but not all the wires) Thanks Chuck

Thanks for the update Chuck. I should be able to help with all of that. I need to know if the ECM is DDEC 2,3, or 4 ?

Thank you
I will note that there is a diagram that Freightliner calls a basic diagram. It is not enough to show all the wiring.

Click on this link for the Vehicle OEM connector and the engine side.

Basically everything on the engine side is the same and the ECM OEM connector will be the same as well weather it is in a Freightliner or another chassis. Please remember to take a moment and rate my answers as that is how the site credits my time helping on the site. Five-star ratings and bonuses are greatly appreciated. Click on the service info link above for the diagrams. I have a highly detailed manual for DDEC IV that will cover installation and setup that I will send over an offer any premium service if interested. Once accepted let me know what email you would like the information sent to. If all you need is the diagram that I've already posted then just take a moment to rate my answers and we can still follow up as needed on here.

I already have these diagrams from Detroit. I need Freightliner diagrams. I need to see wiring in the Freightliner cab that corresponds to 1998 fld 120 with a Detroit engin. The wiring is not the same in the Freightliner for each engin. For instance some of the Freightliner wire numbers that go to engine stuff have a D in front of them.

I have them and the full manual for FLD

I don't know if you will still be there but I have another question.......I was looking at the diagram carefully and noticed a few discrepancies' compared to mine. I looked a the date which was dec. 1996 mine is May 1998. It is still certainly still 95% usefull but happens to be missing some things I imagined they added later. One major difference is that he drawings I have do not have the DCM and display that indicates certain engine problems etc. that mine has ( unless I am somehow missing it on the drawings) Would you be able to get the later version closer to my year? Its still plenty helpful if you can't but would be even better if its available. I would be happy to pay more to too If I would be able to figure out how. Thanks Chuck

Hi Chuck, I believe that might be the closest and I did post an offer for the manual which cover mid 90's to early 2000 models if interested and I will throw in what else I come across in my archives. Just let me know what e mail to send to once accepted.
