Hi @marek4792,

Thanks for posting the TSB.

I went looking in QuickServe (Free subscription) for that TSB or the Installation Note 5414744 to see the part number for what I assume to be the upfit kit containing the cable to convert the existing cable to the connector on the new part. I was unable to find either one.

I also looked on parts.cummins.com and they still list 3770742 with no mention of the replacement part number or TSB.

Are the TSB's and Installation Notes only available with a paid subscription to Quickserve?

Can you please get a copy of Installation Note 5414744?

Do you know who makes the Cummins Part? I would expect if Cummins specified it, it would have a matching connector to the original one.

Thanks for your help. Without this I would have been unaware a better design was available.

Thanks!
