3.0 to 3.4 liter swap help...
Alright, the end is in sight for my 3.4 swap into a 93 T100, but I have a few questions I am hoping someone can help me with...
There is a grey colored plug attached with the positive battery cable that I assumes plugs into the 3.4 fuse box (the one under the hood near the battery) which has a wire within it that activates the starter. I am using the old 3.0 fuse box which is directly wired to the battery (as it was when the 3.0 was hooked up), so how do I connect this grey plug? Does the grey plug in fact connect with the 3.4 fuse box? Do I hard wire it to the 3.0 box, to the battery or something else?
Plus, on the truck itself there are two vacuum outlets/inlets (located near the bottom right of the radiator) that are connected to what I believe is a power steering line that runs to a control box on the passenger side of the engine bay. On the old 3.0 one tube connected to a vacuum hose comming from the top front of the motor and I think the other went to the air box. I cannot figure out what from the 3.4 would connect to these two vacuum tubes. Do I need these? What are they for?
Any advise is greatly appreciated.

The grey connector from your battery harness is for the starter (1 black wire) and your alternator(3 wires red yellow and white) On both my conversions I had to get the starter siginal from the body harness on the truck, your wiring diagram will show you where to get this. I just used an ORS harness so I just had to make a connection.
The alternator, I was able to use the stock wiring for the alternator. The 3.0l alternator connector is the same as the 98 alternator I used.

I appreciate the help....
I have the ORS harness adaptor on order, but I did not opt for the entire piece (not sure if this will solve my prob or not).
Anywho, is the wire I need to connect and find going into my fuse box (under hood)? Wouldn't the original one have travelled there? I do have a wiring diagram, but any help you can offer is greatly welcomed.
