This paragraph shall not be construed to prohibit -

I forgot that the early trailer ABS got power from brake light circuit. like you said doesn't apply to gumpers trailer. Funny what you forget over time.

 

In the mid 90s i had a big cam cummins for a short time. An n14 is basically a big cam with electronics. When i got this truck i want concerned about the n14 thinking of it will all come back to me. Almost a year later and i haven't remembered squat. Its like trying to learn Chinese. This engine is still completely foreign to me.

 

Chinese is hard to learn. lol

 

Very good, I appreciate it.
