hi I'm fairly new to the truck game but have been helping a mate out with some of his trucks, i have the nexiq diagnostic stuff and have managed to plug into his kenworths running the detroit series 60 , but i remember trying to find the plug on the louisville that also runs the detriot series 60, but i couldn't find it ??, do they all have plugs or do you have to use a break out harness to hook up ? or are they just in different locations, it is old and looks like every farmer and his dog has had a go at it any help apprec'd ( i'm going to this job tomorrow ) thanks
I would think that a 93 model would still be mechanical? and wouldn't have a diagnostic plug
i didn't end up getting to it today , but i'm going off memory here that it appeared the same as the kenworths running the Electronic unit injectors . the complaint was engine shutting down and eventually de rated to run slow , and going off some of the other truck the coolant level sensor seems to be a common problem for this. anyhow when i get to it i will post if there is a diagnostic plug, after some research it should be a gm 12pin style not the normal round 6 pin plug cheers
You should be able to bypass the low coolant switch and see if it still shuts down without using a diagnostic tool
Yea for sure , its nice to go prepared tho
