I can't think of anything you might want off the firewall except for maybe the hydraboost but your K30 probably has that already. You could remove the grid heater solenoids from the LH inner fender. The PCM controls the Alt and AC on the dodge. You could go through the work to retain that, but is pretty pointless IMO. A Ford external regulator will get you set up on the charging. For the AC you'll use the GM controls any how. For grid heaters you can use a timer relay so another thing the dodge PCM won't really be a benefit for. Besides, the next owner will need all the wiring and PCM to make that dodge a runner again. They'll also need the TPS off your throttle bracket. But you might keep that if you ever want to do a newer electronic type of cruise control. The only part of the dodge harness you might want to keep would be the connector for the fuel shut off solenoid and maybe the battery cables to the starter and alternator if they are any good. I usually just build new. The used ones are nearly trashed up here. But if yours are usable, it might save you some coin.
