Snap-On VH45DE Wiring Diagram

[tmorgan4]

I just received this in an email from my uncle who's trying to help me with a couple wiring issues. My brain always hurts after looking at the giant one in the FSM, so I thought I'd share this one. It's all color-coded with numbers between pages.

Maybe someone could host it on NICO so it doesn't go away in a few months.

Thanks Tyler. Got it saved.

Where can one get a copy like this for other engines - say a 4.1?

[tmorgan4]

The guy he got the diagram from runs a Mercedes repair shop and has a subscription to the Snap-On literature. Not really available to the general public. I'd try and see if you can bribe a local mechanic and see if he'll give you one for a few bucks. Maybe Snap-On would sell you the material for a single vehicle...no idea. I'm curious what they publish besides the diagram.

are you using a US VH41? If so, it might be better to go with an aftermarket ECM IMO. The OBDII ECU is very limited.

Thanks Tyler. Got it saved.

Wes, is it hosted on the forum, or have you got it hidden away?

Good question as the link is DEAD.

I can re-upload it there is interest and I can find the file. My computer just crashed and I lost a lot of stuff but I should still have it on my email server. It would be a nice thing to have hosted here on NICO as it's much easier to read than the FSM diagram.

I'm interested. Wes, can you post it?

Any info needed I can get from school. From alldata. Going to try to make a copy if possible...Give me year and model and what info you need. I should be able to upload pics on my photobucket.

I have it all, and hosted all of it for you on my site.

Good post...all the wiring diagrams all in one.

The 5th and 6th links Steve posted are the Snap-On diagrams I uploaded. All the lines are color coded so it doesn't give you quite the headache the FSM does when trying to trace lines.

thanks tyler.
what do you think the best way ?easiest way is going to be for me to wire up everything?
which computers do i HAVE to use from the q45 cause there are like ten of em.
i have BOTH my 89 pathfinder harness and the the entire q45 harnesses both out of each vehicle, laying out across my entire living room floor, next to each other,. i have both fsms.
i swapped the fuel pumps as they are identical in shape, do i still need the q45 fuel pump computer?
thanks for the help.
i was also thinking about this idea.
what if i plug the engine harness into the q45 computer, and the original harness into the original computer to run everything else? idk
i honestly dont know anything techinical about wiring so any help with help alot.
