so I have a 01 ram 2500. when I bought the truck the obd 2 is broke off an just the the wires are hangin.. I stop at the local junk yard an picked up another one the lady gave me. only problem is the color are not the same as what I have, would the obd ports be different from a gas to a diesel? or does somebody have the wire pin locations or a diagram for it?

 

Plug is the same.

Color code should be as follows.

 

I don't really understand the number part. can u kinda please explain. im not quit sure like what pins go where.. thanks

 

Ok, the number should be on your ALDL connector, should be molded in, can't remember if they just identify 1 or they identify both rows..

Anyway, the small number shown at the ALDL connector is what pin location it goes in. The number and lettering shown on the wire is standard Chrysler nomenclature, for example, loot at the wire that goes to pin 16, it is from circuit M1, and is a 20 gauge pink wire, thus the designation M1/20/PK.

Make sense?

 

yes I do now thank u and did get my obd fixed so now I can finally put my programmer on

 

what the heck is that... that is Calculus right.......

where is my 10 year old son. he can likely read this....

I should have learned more on electricity and wiring besides dont touch or pee on that wire.

 

LOL, C'mon man, I hate wiring as much as the next guy, but I love my Cummins more...........

If you ever get yourself in that mess, PM me and I can walk ya thru it.
