I am in the process of swapping a Cummins diesel into a 1996 E Super Duty that currently has a 460 engine. Doing some of the preliminary changes before I tear it down. One of the things I want is a factory style tach in the instrument cluster. I did find a nice cluster from a 1992 F-350 diesel truck.
I have read up on swapping the gas F-series cluster into the gas E-series van but have seen nothing on using a diesel cluster for the swap. The diesel cluster has a 4,000 rpm tach vs 6,000 rpm gas tach. Does anyone know if the gas and diesel wiring is the same or if there are any other differences? I have the 96 E-Series wiring diagram, but can't locate a 1992 F-Series wiring diagram to compare and see what all wires I need to swap out.
Did the swap. Everything seems to work OK except for the fuel gauge. It stays at one spot between 1/2 and 3/4 full. Even filled up today and it didn't move. I may even post this on the truck section.
I'm guessing you already read through this one, but if not, mine is near the end.
I too had trouble with the fuel gauge. The truck gauge panel doesn't have the "cut" in the anti slosh module wiring on the panel film like the van. When I put the anti slosh module into the truck panel, It didn't work right. Cut the trace on the panel then, it worked (with the module). Only then I found the wiring diagram I was using was different for my year. A little troubleshooting and quick wire relocation and presto, factory tach.
Silly, but I still get a kick out of having the factory style tach in a van. Trouble is nobody else around me is old enough to know it never came with one, they can't figure out why I'm so wound up over it...?
Thanks, but I tried everything that you talked about in your thread. Even the jumper from gray plug 13 to 14. Gauge read WAY past full.
Tonight I did get the gauge to read correctly when I removed the Anti-Slosh Module and re-connected the printed circuit loop that I had cut last week. I guess the 1992 diesel cluster is a little different. I guess I will have to live with some needle movement since I can't figure it out.
Wow, the fuel gauge needle moves a LOT! This may take some getting used to.
From "excessive" consumption?
If the needle movement is just fuel sloshing around in the tank and the dash gauge too quickly displaying it the "anti-slosh" module is perhaps not working properly or was bypassed completely?
