using the 4.3l V6

[chopit]

1952 chevy 5 window s10 swap

Ok, got my 95 s10 tore down, sold a couple of parts. Going to do this build on a major tight budget.
So the 95 4.3 and auto trans run great and I already own them for free..so I am thinking about using them?
Not looking a build a racer...just a nice dependable cruiser.

Unplugged all external harness from firewall etc. no cutting.

Now I am trying to find threads using this setup so I can figure out what I need out of the cab...full cab harness? or go simplified harness? And of course other info.

(already promised unmolested s10 cab to a friend but he has another wrecked cab I can scavenge.

Not having luck finding those threads in search if they exist. searched this forum for 4.3...V6 and other random searches

So if somebody that has done this is around please post up your thread here..or if you know of somebody's thread that would be helpful'

thanks in advance...a wiring newb.

Here you go. not a lot of detail but he got it done.

Thank iowa, I'll check it out

I did mine with a 99 chassis and drivetrain and kept the whole wiring harness. in order to use the whole harness you need to keep things like the column (for the turn signals and hazard switch) and the brake switch. I would guess I used a whole bunch of the s10 that most guys throw away when swapping.

its in my 49 chevy thread in my sig, actually its the 47 gmc in that thread, but the chevy is getting an 03 swap of the same flavor.

If your like me you don't like the wiring nightmare. You could just throw a carb and intake on and keep it simple.

Thanks Joedoh,lots of good info.

I here ya Jeff, but if I go with early carb and intake, I'm afraid I'll lose the power I could live with using efi. Carb 4.3's are known to be a bit more gutless.

...and I think where my mind block is that 32 years ago I built one with a carbureted 350/turbo 350. All these years later I feel like I should at least attempt to take advantage of a little later technology.

I think this guy only does LS stand alones. Pricing is good. Might should call and see if he would tackle my harness.

Not committed to engine choice yet, plenty else to do, so I'll just keep at my research on it.

[joedoh]

yes, EFI makes it so sweet, and we kept a host of other goodies like dome light and key/lights on bonger.

we laid in the entire harness including all lights in two hours. plug plug plug. aside from doing a column relearn because I changed the column to a floor shift model, it was connected and ready to roll. I flat out dare anyone to compare that to an intake switchover to carb and installing even a pre cut aftermarket harness.

If you don't know much about wiring you can still do a good job if you are detail oriented, able to take good notes, and patient. But if you slap it together and don't know much about electrical you're going to have a heckuva time if you have to troubleshoot. And you will probably have to troubleshoot.

How much wiring do you want to try yourself? Is it throttle body injection or the "CSFI" engine? Are you keeping the transmission? How many of the conviences and accessories are you looking to keep? And really, are you comfortable taking on a larger project?

[chopit]

Its a 95 throttle body will keep tranny if I go this route. ...and good questions. Same ones I keep asking myself

[chopit]

Maybe I'll just hunt down an old 40's Cadillac 346 flathead

i just dont understand the fear of using the factory harness, it is light years easier than buying even a premade "painless" harness and laying it in.

the motor harness and frame harnesses will unplug, all of it will stay wired while you work on changing the body. when you are done, put the engine compartment electrical components in the same rough position they were in the donor, and plug it all together. the factory harnesses use unique connectors, or if there are duplicate connectors they are used in different areas that couldnt be plugged together in a million years.

I work in systems engineering. once you get used to looking at a vehicle as a combination of systems, you can easily see the best way to mix and match different systems on the same vehicle. the harness doesnt care what the body looks like, it does its job when the right components are plugged in. inputs and outputs, as long as they are appropriate, stuff works. keep the column for the key harness, or even find a way to make it work with a different column, if you need to.

[1project2many]

Chopit...

That system is a good one to use. If you don't have the black underhood computer then there is support in the tuning world so you can tune out or turn off some of the systems you don't need. The wiring harness isn't too complex, either. The instrument cluster is mostly separate from the computer harness, cvruise control is a separate part with its own built in controls, and the interior accessories are not controlled by the engine computer.

Overall I have found EFI retrofits to be better than carb installs. I put EFI in my truck in '92. I have had to do very little maintenance since then. That's 23 years. No carb overhauls, no fuel pump leaks, nothing. Each spring I connect the battery, turn the key, and start the truck. It's that easy. This year I noticed that the original damper from '65 needs replacing so I'll probably do some other work during the process. But still... 23 years. If you decide to go this route there are plenty of people here that can provide advice. IMO a frame swap or front clip is a heckuva lot more work and a heckuva lot more detailed that swapping a harness with 20-25 circuits.

my build uses almost Everything from a 1996 S10 Blazer.... 4.3L, 4L60 OD tranny. I kept the steering column, pedal assembly, full gauges, cat, charcoal canister, full computer hookup. runs fantastic and still gets 22 mpg. Factory cruise control is very nice to have also. the only things I did not use was the anti-lock brake unit (it was as big as a battery) and the air bags (wanted a nicer looking steering wheel)

the only things I needed to strip from the factory harness was the power windows, locks, and mirror wiring.

I did redo all of the factory connectors because it looks better, but not because I had to.

[joedoh]

really nice build msaint! the 95-7 column/pedal setup looks a lot easier than the 98-03 setup. I did the same with my build in fact had some deja vu looking through your thread. I used the s10 stepper motors in the factory 47 gauges

[tmoble]

>>> I used the s10 stepper motors in the factory 47 gauges

Wow. Would you be willing to post up detail on that? I think there's lots of guys who would be interested in that. stepper motor gauges behind stock appearing faces? Oh yeah.

[67chevemall]

You guys are brave. I won't put a 4.3 in anything, unless it was going to be blown up.

[joedoh]

the gauge how to is in my build pictures, but here is what it looks like

[tmoble]

that is a killer deal.. I went and looked at your build thread but got sidetracked by some od the other stuff you did. I'll try again.

[BlueJeep]

v1.0 of my build used a 95 s10 4.3 and the stock harness. See the early pages of my build in the signature.
