Lmm injector harness

[JDPlowboy]

I have 2 lmm's at the shop with injector harness problems. Haven't dug into them yet but are the connectors still giving problems on the newer trucks or is it more than likely a chaffed wire? I'm sure I'll find out shortly. But was just wondering if this is a common problem still.

I haven't heard too much about the harnesses on the LMM.

I've seen a LBZ with harness/connector issues... It had gotten head gaskets and 2 sets of injectors in a 2 year period, so they were plugged in and unplugged multiple times...

First truck had a ratty harness combined with coolant leaking right on it... Second truck had a broken bale connector lock on the lower connector.
