Didnt get a chance today, something came up. Only thing you use from the 3g setup in there is the green red tracer wire. The rest have to be split out of the harness, and dis guarded. I'll take care of it first thing in the am. I got busy got a chance to get parts for a truck of mine, fresh into the yard, got to get there and grab what I need before everyone else does.

dLooks like a great write-up there, PrimeTime.

Except that all the photos disappeared? It looks like it would make a lot of sense with those pictures!

PS: You're in Onaway, Michigan? I grew up in Cheboygan, MI and went to MSU. We always had jokes about "Chicks from Onaway!" I've got a piece of property out there at Long Lake between Cheboygan and Onaway now.

All good. He has some things I can incorporate
I also intend to add generator to 3g, 1g to 3g.
I talked to Dunkin about making it a sticky when it's done

That'll be good, Dusty!

Do you want me to find some "youtube videos" that might be good for a link at the end of your write-up? I've watched a few. I think one or two might be useful, but want to see the write-up first so I'm not handing garbage work in to the Instructor.

No, I think I have it covered. I have several trucks here, 1 is still 2 g, some are 3 g converts, and I have wiring harness parts to show, plus diagrams saved in the laptop.
Shame Smokey is down, I already wrote the article on another site, he could have just copy pasted it.
All good tho, last time, the pictures from there were huge, and made it hard to navigate

Didnt have time to put it together today, but this should help tell if you have 2g or 3g
The 2g has a fan, 3g dont

I'll get to the write up in a bit, had some things to take care of.
The conversion looks like this

There is a fuse for electric fans too. The 175 amp buss fuse is the alternator

your truck wont require such a large wire, this is a plow truck

Ok, have new alternator but have not gone to see my truck's alternator. Mechanic says he believes he HAS SEEN a fan on it, therefore I am sitting with a 2G!

Question: Where in the world could I get those wiring connectors? I didn't order from rock auto, thought it was just splicing and the ground point, but after looking at the back of the new alternator I see it has a comm line similar to a (if not exactly like) the ODB1 small plug for testing and then of course there is the larger plug that is not the same as the current larger plug on a 2G.

And do I need to buy a relay? I have a 130 amp alternator, so should I get something like a 150-160 amp (20% bump) for any surges it blows or go for something tighter like a 135 or 140 amp relay? I feel like a 5% variance is too narrow and will be blowing the relay too often, but I could be wrong. Unsure about the performance of a 130 amp, but most engineers normally have a 10% or better buffer in guidelines and ratings, so I'm expecting the variance to be at least 143 amps so a 150 relay fuse is probably the minimum.

Stream of consciousness -- tips and guidelines appreciated! :)

1. Relay size minimums based on 130 amp alternator?

2. Where to get new pigtails for wiring harness adaption (splices) to mate up proper in the 3G alternator.

I will give you everything on ebay you need to buy, give me a minute, I had to run an emergency.
I also have to tell you what to cut out, and what to save on the 2g.

Not able to post pictures from my laptop, for whatever reason, so I'll try to be as discrpiptive as possable

1. Unhook battery
2. remove the fusable link from the solenoid for the alternator.
best way to find this, start at the aalternator, and untape, un harness the wires back to the fender. becauctious of the red/green wire, we are going to reuse this

3.at this time remove the alternator and plugs. keep the red/green. othes can be discarded

Build your wires from the 2ag. 1 from hot side solenoid to top of buss fuse, 1 from bottom of buss fuse to alternator. leave some slack, make sure to not pinch or bind them. solder the ends, and heat shrink. I didn't put heat shrink on your list, you can get that local

I can take some pictures of the trucks and connections if you need them tomorrow.

Funny thing, I went back and looked at my 92 flareside project truck, it's 3g.
the 93 flareside sitting next to it that was my son's is 3g.
My 94, the 94 Cantorian, and my 95 Eddie Bauer are all 3g.
You must have ended up with a "parts leftover " truck.
post the build date off the door please, this one has me stumped1
