It's definitely allowed, I've done the swap both ways, actually.

•p-pump sollenoid shutoff? On my first gen its a small wire plug to the ve-pump
•wiring? With my old harness, alternator/voltage regulator and sensors. Can I use just these?
Yes, you can use all of the OEM harness and sensors (be sure you swap the temp senders), but you'll need to re-do the wiring for the fuel heater and add a "start" circuit for the P-7100 solenoid.
There are 3 wires on the P-7100 solenoid plug, and the color codes equate to:
Black= Ground.
Red= Run (hold).
White =Start.
You'll need the following:
3 separate lengths of 14 gauge wire in Black, Red and White.
3 female spade connectors.
2 loop connectors.
1 male spade connector.
Since the FSS on these trucks are "hot" while running, as well as cranking, it needs to be routed to the
RED wire in the connector, with a female spade on the one end and a male spade on the other.
The
BLACK wire, obviously goes to ground, with one of the loop connectors on one end, and a female spade on the other, which goes to the BLACK wire in the connector.
The
WHITE wire gets the other loop on one end, WHICH GOES TO THE
STARTER SOLENOID POST and the remaining female spade on the other, which goes to the WHITE wire in the connector.
This will solve the Start/Run Circuit scenario and it's 100% doable with no wire splices, JUST CONNECTORS and
NO RELAY WIRING BS NECESSARY!!!JARR wrote:•radiator shroud? Apparently theres some clearance issues, someone mentioned swapping my "Idler assembly" over to the 2nd Gen and that will work. Idler assembly? Do they mean all pulleys or just the rad fan assembly?
Depending on whether the original engine in the 1stgen was intercooled or non-intercooled, this can get tricky, but I'll use the
1STGEN INTERCOOLED as the receiver in this case:
You need the fan hub, pulley and radiator & shroud from the 1stgen.
The A/C compressor from a 1st gen INTERCOOLED (different line outlet locations)

Absolutely. You'll need the 1stgen starter, too.
JARR wrote:•Engine Mounts. I don't have the mounts from the 2nd Gen Frame so I'll be using my original engine mounts. Is there any durability issues here? Theoretically its all the same... right?
The OEM 1stgen mounts will work fine, 55HP, If it's a 215HP engine, will hardly even bother the stock isolaters.
JARR wrote:I'll also mention that Im acquiring a 1st Gen I/C radiator support and grille assembly from a 93' . My truck is a Non I/C 89' w250 4wd so I also need a new radiator and intercooler setup. Any suggestions on a rad and cooler?
This part actually answers some of my concerns.
With what you have on the 2nd gen engine and the OEM one you should be good to go EXCEPT FOR THE
A/C COMPRESSOR AND
FAN SUPPORT HUB ASSEMBLY W/PULLEY.
