Fuse Box and ECM Placement

In looking at building my 2nd AD truck (and thinking about what would I do different this time?) I have seen a few pictures of trucks that have the bulk of the electronics under the seat. This seems like an interesting idea to me and a great way to free up space under the dash. Other then needing a "flip up" seat bottom to access everything... what are the pros and cons? Anyone have any first hand experience in doing this?

Re: Fuse Box and ECM Placement

I did this on my 50 with a TPI motor.
The only thing to think about is since the fuse panel is not under the dash you will need to run wires to and from the fuse panel to everything in the cab.
I used a trunk mount wiring kit to get the extra length wires.
Also if your motor requires a computer harness make sure it will reach to where you want to mount it.
It was painful to remove all the pins from those computer connectors to be able to have a reasonable size hole for the harness through the floor.

Re: Fuse Box and ECM Placement

Good answer there. Fuse block where you can reach it and see it when you need to which may often as not be on the side of the road in the dark in a rain storm. If I had my drund thers I'd put both (if I had both) in a panel behind the drivers seat where I could lean the seat forward and pop off a panel and easily access everything. I've spent too many hours on my back under a dash in real nasty weather checking fuses.

Re: Fuse Box and ECM Placement

My fuse panel is under the dash. I put the TPI computer under the seat and the Dakota Digital boxes in the glovebox.

Re: Fuse Box and ECM Placement

while you are on electrical stuff also think about putting a master disconnect switch in the battery cable where you can reach it from the drivers seat, After a friends 40 Willys caught fire (electrical) on the I65 bridge into Louisville. and was saved because the passenger could reach the disconnect, I've made it a point to put it where I could reach it when alone. just a thought, do all this work to build something this could help you!
