Hard to find information for 454 swaps online.
I swapped a 454 from a 1996 (obd2) gmc C2500 suburban,
I was able to swap the whole harness from the suburban and get the engine to run perfectly in-my truck
Only problem is that only certain gauges are not working
Fuel gauge pinging to the left when in park but pings to right when in neutral or drive
Oil pressure gauge pinged to the right no matter what
Tachometer not working at all
blower motor, wipers and windows everything else works, was able to plug harness in from my transfer case to the 454 transmission harness, so even 4x4 works.
at first I thought it was a ground so I finished putting all fenders on and hooking up body grounds,
I do not want to swap dash from the suburban as it does not have an airbag and mine does
Do I need to re pin at the bulkhead connector? Or is it something else?
I do have the cluster from the 454 in my truck and also have the whole donor vehicle still
