Crate Motor Wiring Questions

[mikester]

I need some help guys. Ive been trying to get this figured out but Im at a standstill.
The crate motor I bought has the serpentine setup with the new CS alternator. Pretty sure its 105 amps. This is where things get confusing for me. The wagon has the same harness as the coupe. The photo is the same one I posted back when I was trying to figure out the starter/alternator wiring in the coupe.
The alternator output wire AND the hot wire coming out of the 2 wire plug went into the factory splice and then one to the starter and the other to the bulkhead connector. The AC feed was also in that splice but I removed it when I got rid of the AC. Odd that they werent seperate wires and both went to the same splice. Maybe someone can explain why its like that ? I have no clue.

The CS alternator has a weatherpac 4 post connector. I looked online and American Auto Wire has an adaptor wire for this. The wire only uses 2 of the 4 posts. The instructions that came with the crate motor say you need to put the hot wire from the weatherpac connection to the output post on the alternator. Im confused. Why ? More than that, what about the wire going to the bulkhead connector like the original plug ? And what about the hot feed to the AC plug that comes out of the factory splice ?? If I run the wire from the plug to the output post thats gone.
A couple of the people I asked about this said to use 8GA wire from the output to the starter. The original alternator only had 12GA from the factory. I know. 105 amps compared to 60 amps.
If I use 8GA to the starter how does that effect the 12GA going to the bulkhead from the starter ?
Im sure theres going to be more questions as the answers start to appear. Alll you folks have been a wealth of info over the years but please be patient if I have a hard time grasping this. LOL
Im trying to do this without adding fuse blocks, relays etc, Can this be done ???

I saw that video. Its on a truck and not a g body. I dont know if a truck harness has the splice that a g body has. Just that video isnt enough. What about the instructions that come with the motor that say the wire from the plug goes on the same post as the output wire ? Also if the output wire has to be heavier gauge what do you do with the splice ? Using an 8 or 10GA wire to feed a splice that has 12GA wires in it doesnt sound right.

They dont know what the engine is going into

Maybe a car maybe a homemade car

Anyone else ??

Thanks but thats only answering one part of my question though. What about the 8 or 10GA wire from the output post to the starter ?

The whole red Circuit 2 is 12 AWG on our cars. From the fusible links (16 AWG) to the main harness with the one wire, then from the links to the alternator screw post, to the main splice which leads to the alternator plug & A/C blower fan (if an A/C car), then to the main harness. If still quiestioning, check the size wire on a '91-'96 B-body or a '93-'02 F-body to compare what the used. From what I've seen on those adaptor plugs they use a 12 AWG wire for the Circuit 2 wire. If it was me I'd stick with the 12 AWG wire.

If you want juice: 1/0 wire from the alternator to battery, battery to starter, ground from battery to engine/chassis, chassis to body, etc...

Remember that the electrons flow negative to positive, so grounds should be bigger than the hot leads.

So, the 12 AWG is good for the 105 amp alternator output wire ? I used 12 AWG when I remade the splice on my 81 but thats only a 60 amp alternator. I ran it like the original but I took the AC feed out since I switched to heat only. I know I have to redo most of the wiring from the bulkhead to the motor and I know its not a big deal but the whole wire size/alternator/splice thing has really held me up. I only want to do this job one time.
I'll order one of the adaptors on Monday along with a new compressor pigtail.

Thanks for the info !!!
