Hi I'm Gavin and I have an OBSession
So I started this dash swap in my 94. Removing the old dash without hacking up the wiring was pretty difficult but I managed to do it. I would have preferred a 95 diesel harness but I could not find one so I'll be using the stock 94 harness with some rewiring and splicing. So far the cluster was a matter of repinning, I had to splice and dice wires for the headlight switch and I'll be doing the same for the fuse box.
I'm doing this in a 6.5 diesel truck, so I have a 97 diesel cluster and a 98 dash from a truck that had a Vortec 5.7, and this far I've successfully wired up the gauge cluster (a matter of repinning the connector) and wired up the headlight switch. I still have 3 or 4 pins left over from the cluster swap that I need to figure out since they must be diesel specific but I'll be sure to document what they are to possibly help others with a diesel. RPM for some reason only works if the headlights/parking lamps are turned off. E-Brake, Fuel, Voltage, Temp, Oil Pressure all work, check engine light works, "wait to start/glow plugs" light works but is completely opposite (where it's only off if the glow plug relay is actually working). I haven't driven the truck with the new cluster so I have no clue if the speedo works.
The headlight switch was also super easy, just a matter of matching colored wires. I had three wires left over, two purple and I think a pink which I suppose are for the Dome Override switch.
I am going to swap the mini-fuse block in next, and hopefully test fit the dash. Next time I go to pick n pull I'll be getting a steering column and the metal brackets required to hold the new column up and the bracket to support the passenger side of the dash.
As far as the HVAC controls go, I'll be using the 94 controls until I decide to pull all the stuff I need for wiring up the 95+ controls.
