1999 freightliner fld120 CAT TO N14 CUMMINS

SO I need some info on my fld120 vin 992067 I threw a rod on my c12 cat and pulled it out and took a n14 out of a day cab and put in in my fld120 the day cab was a fld120 but did not have jakes cruse on the shifter or a switch for the fan. when I got the n14 installed it ran but wouldn't shut down so I put in a kill switch to the fuel solenoid so I can shut it down now. went out for a test run and it only get up to 1600 rpm and goes a whopping 53mph took it to cummings and when they tried to hook to the ecm ports they couldn't get anything from the ecm in or out of the cab. o I changed out the throttle pedal the one from the cat did not work.so my buddy has a 1998 fld120 with a n14 out of the factory and he thought that the wiring harness from the fire wall to the ecm is what I need to replace but I need to see if his is the same as mine and I cant get anyone to send me the wiring diagrams from both trucks I need to make sure the pins are in the same position coming out of the fire wall. his vin is 971116 the part number is A06-2321-000 any help?

 

thanks for the spelling lesson good buddy!! Mawk industries will take a week to do the work on the harness.

 

the engine is running and I drove it to get the ecm flashed but the ecm didn't have any power to the outlets that's why it only runs down the road 53 mph
