Hey everybody, First time posting. First, I just wanna thank everyone. Ive learnt a great deal throughout the years thanks to this site just by browsing around most times. Ive got a question to ask. Im very concerned about aging wires and harness on an 01 Mack MR688S with an e7-350 E Tech engine. Awesome engine, never give much trouble except for the time to time wiring issues (oil pressure harness, range sensor harness..., the VECU that once went bad on me, etc. I wanna keep this truck going and wanna consider keeping an E7 Mechanical engine as a back up. I've read great things on the E7-Mechanical. My only issue is the mechanism for the mechanical throttle for this particular model. Would anyone happen to have a diagram with part numbers showing how this MR cab over model's mechanical throttle works and what parts are needed? Also, if anyone know of someone that sells an aftermarket wiring harness set up to run the etech engine as a stand alone from the rest of the trucks original harness, I would also consider that path.

Hey guys, new here. Ive developed an unusual problem. My mackś engine shut off light appears while going up or down hills. (I live in the Virgin Islands btw). This had never happened before. Ive researched and understood that engine shut offś are usually related to oil and coolant. Coolant level is pretty good so its not the low probe. Ive had the electronic malfunction light turn on with a 3-2 code for ages and has never affected the truckś performance. Any ideas what can cause this? Its an 01 MR688S Cabover with an etech 350.
