2015 Sprinter 2500, 4 Cylinder, Cargo Van
Hi all, I'm new and I've really learned a lot from all the great content on here, but I'm having trouble sorting out this MB diagram on fuses/relays
There are two things that I would like to do, ultimately:
1.) I'd like to locate my fuel pump relay so that I can build in a custom security switch to disable the fuel pump
2.) I'd like to locate my (?) starter relay (?) or other appropriate relay so that I can link my Blue Sea ACR 7622 to the ignition wire so that my auxillary battery and starter battery are isolated during cranking/starting.
Using the MB diagrams/maps I can locate all the relays, but it seems that there are multiple relays sometimes of the same function. For example, there appears to be a fuel pump relay under the drivers seat at R5, but there is also a fuel pump relay listed in the main panel to the left/under the steering wheel at R3. I've run into the same issue with trying to locate my starter relay.
Also, another source of cofusion is that sometimes it will list the relay's function, and then say that it is a terminal of some sort (e.g. R5 ; K40/9 ; Starter Relay, Terminal 50). What does terminal 50 refer to??? sometimes it will say terminal 15 or 87 or 30 and I have no clue what to make of this.
Any help will be sooooo appreciated!
Thanks in advance.
