Allison 5sp: NSBU Connectors

[WisconsinHick1]

So my great beat to heck 2wd truck has a couple of connectors cut out that I am in need of both of them. Anyone know a place to get them? Rock auto has them with pig tails but I would be worried about splicing them in. Or would I be better off if someone has one replacing the whole harness? Would a 4wd harness work?

Why are you worried about splicing them in? I had my old ones literally seized into the NSBU, so they had to be replaced. I spliced in some fresh pigtails and it worked perfectly.

I was worried about something not communicating properly. Where did you get your connectors from? Anyone have a wiring diagram so I know what wires to splice together?

You shouldn't need a diagram, it's going to be color for color crimp connectors with heat shrink..

Hopefully but on rockauto they showed the pigtails all the same color.

Merchant sells one that looks color coded.

Rock auto pigtails are all grey

Just grab a wiring diagram, this isn't rocket science. You can do it.

Nothing is ever as simple as it ought to be. I'd do the MA one and call it good.

Well I have my connections and have a diagram but there are multiple yellows and multiple greens and black/white. I'm a little lost now.

Too bad they didn't make one that was color coded! :hug:

 

[WisconsinHick1]

Well the colored one wouldn't work any better as it is the wiring harness itself that is a pain and the connector with pig tails has nothing to do with it.

I am in need multiple wiring diagrams to get the wires correct.

Label each as you cut each wire...

I didn't cut any wires they where already cut.
