ivanuke Posted May 6, 2019 Share Posted May 6, 2019 Hello, Ive contacted my local mack dealer (Vanguard) and they were not very helpful in determining the correct item to purchase to obtain an electrical schematic for my truck. I also contacted mack directly with no response. Hopefully someone here can chime in. I purchased this from the mack eMedia center 8-217-2007 Electrical System Troubleshooting, GU, CHU, CXU, Pinnacle Chassis Wiring Diagrams Is the CHU the same as my 2001 CH613? I'm trying to look at the reverse switch wiring from the transmission to the dash as I am no longer able to hear my rear siren and rear back up lights dont come on and having many connectors unplugged that I need to check continuity for. Thank you. Quote Link to comment Share on other sites More sharing options...
Mack Technician Posted May 9, 2019 Share Posted May 9, 2019 You have the wrong diagram ordered. You should have posted for assistance first and then ordered your diagram instead of the reverse order. Quote Link to comment Share on other sites More sharing options...

Thank you. This is the diagram for your truck reverse circuit. Go to Fuse (FU42) 42 in the right upper corner and follow flow.

Mack Technician Posted May 12, 2019 Share Posted May 12, 2019 Go to your dealership at 8PM with a flat of white printer paper. Ask the night foreman/service writer to print off the wiring diagrams or allow you access to print them off. If your a customer they should oblige. If they do it, come back with a large flat of bakery. Tips and food make you an “A list” customer. Night shifters at a dealership are the most under appreciated creatures on earth.

I see your 2001 schematics for sale on Mack E-Media for $54. Oddly, they are $22 for a 2000. Must be because of chassis mating. They group CL with CH on pre-2001 then the conversion occurs and chassis-groups CH with CX in 2001. 01’ is a 6 pc set.

I'll place an order for that. I also have a 2005 CHN613 but do not see an option to select CHN, only CHU. Hopefully the schematic I purchased originally is the right schematic for my other truck. Thanks again for the help. 1 Quote Link to comment Share on other sites More sharing options...
