If you have the engine number you can go to http://quickserve.cummins.com and sign up for a login where you can obtain engine repair manuals and wiring diagrams and much more but it will cost you usually around 50 bucks but very worth it if you plan to be the one to work on the engine.

what would I need for a fuse size to put in between the on and off switch and power point?

Technician: CumminsApart, Cummins Technician replied 8 years ago
Hi There,

You can use an inline 3AG type fuse holder and 25 amp fuse should be ok. Be sure to use a good non plastic cover for your harness to protect it from the exhaust and engine heat.

good luck
Pete
