The heavy gauge pink wire at about 9:12 is 12 volt switched for ignition. You can run it directly to your HEI distributor. You'll probably need to splice on the HEI connector to this wire.
This is a huge help for me. My 2.2 2nd gen threw a rod and I gave a 305 I’ll be putting in her. I’ve never done anything more than a clutch replacement so can’t wait to learn a thing or two :)
I had found some wiring diagrams for the truck online (forums, Facebook groups) and found those very useful when I started messing with the wires. Would recommend trying to find one for references also.
Fifteen years ago I got over enthusiastic removing "extra" wires from under the hood of my 90 1500 4x4, what a party that turned into, for my Sonoma I went chicken shit with a Painless harness. lol
Yeah I don't like messing with the electrical stuff. I had a detailed wiring diagram for it before I cut so I felt ok about snipping the wires lol. The painless stuff is nice, I would've used that on this if I had too and will use their stuff on the next project I have waiting once get the s10 on the road.
Have a 94 with a ton of wires running a carb motor is like a 90 or so. What about ignition, lights, blinkers, I can't believe you can cut all those wires without having a problem.
Thanks! For the hei distributor as I am using there is a medium sized pink wire that would go to one side of the distributor and then a green wire will be run from the "aftermarket" tach to the other connection on the distributor.
Nice! I saw one set up like that this past weekend at a local car show. I spent alot of time studying it to say the least. I like the pro street look on hotrod builds myself. I think the S10's are great platforms for them too later down the road I may convert it to more of a pro street truck myself. As of right now it won't be set up to that extent but hopefully will run pretty good as a "street truck".
Yeah leaves it open for many possibilities lol I originally got this and intended it to be a simple "budget build" to cruise around in but it seems to just be getting further and further away from that the more I dive into the thing. I've even looked at different motor and trans options it could have in the future 🤷♂️
@@304customsgarage ; I got very lucky and bought my Sonoma project from a friend with almost every single part sitting mostly in the bed of the truck in an atmosphere controlled garage since Jan. 2019. I'm lucky he's one of those guys who tends to go overboard when he builds a toy with my Sonoma being no exception. The engine was dyno'd on 89 pump gas from the local Kwik Fill station so I don't see fuel as an issue. It didn't come with a trans so I ended up picking up an 4l80e freshly rebuilt 5000 miles ago from a friend. The friend who sold me the truck owns the tranny shop that rebuilt the trans (500.00). I know I won't be looking to change the driveline in this truck because I can't afford to match what is already there. When I say he go's overboard, he machined in oil squirters to spray the underside of the piston's to help keep them cool while using nitrous (if I chose to) and bushed the lifters, first time i've had a friend do that for a street engine.lol. This thing should be quite the street monster when it rolls out in the spring. It's got a 1st gen. 17* 399ci.stroker.
Question, are you going in with a carburetor or TBI fuel injected... IM PUTTING A 95 TBI FUEL INJECTED 5.7 iN MY 90 s10. Can i use everything from the 95 TBI & PUT IT IN USE FOR MY s10 ..
Yes I am using a carburetor. As for the things stuff I'm not 100 percent certain but I imagine you could use some of the stuff on the v8 swap. If going that route however I would label all the wires as you unhook them and set them aside vs cutting anything out. Sorry I can't be of much help for the Tbi stuff.
Do you have a wiring diagram that you could send me?I'm doing the same with my 89 s10 cameo.Im going to retain the stock original digital dash. Thanks in advance for any advice and help.
I have not actually started hooking up wiring to the motor and such yet but hope to get back on it soon. I've been pretty busy and haven't got to spend much time working on the truck lately.
For the power if using an Hei distributor you should be able to use the medium size pink wire coming off the fuse block on firewall. Needs "switched power" and the the other in my case would be a green wire for the tach. I bought a pig tail that clips onto the distributor connection
How would I go about getting the stock in tank fuel pump to work with my 350 sbc and still work when you click the key? Do I have to cut the computer stuff out to do that/is the wire from the oem pump going to that computer?
@@ROOSTERBOOSTERRACING I left the computer in, from what I can tell in the diagrams, once the oil pressure sensor sees oil pressure it will kick the fuel pump back on.
If I was near gladly help out! I saved the clipped wires just incase I need to run something from them, really don't need much from the "clipped off side" to run a sbc with carb.
OK thanks man! I'm working on a 96 s10 build with a carbureted sb 350. It doesn't have power windows or any of the other fancy sh!t 1996 h0ad to offer lol so I'm kinda wondering just how hard the wiring could be¿

Hack job garage. Probably should have labeled the wires before you pulled the 4.3L. So you know what the wires connected to like the water temp, nox sensor, external coil, etc.

I’m building a 1991 ext cab, short bed. The harness was already cut up. I’m trying to follow your steps.

Because from diagrams it looks like tan and white could be a ground but I didn’t test yet..
Holy cow. I know I’m a little late but I’m already loving this channel My only question is that I didn’t see the distributor wires
Thanks! For the hei distributor as I am using there is a medium sized pink wire that would go to one side of the distributor and then a green wire will be run from the "aftermarket" tach to the other connection on the distributor.
@@304customsgarage thank u very much. I really appreciate it cuz an electrician I’m not. Lol.
I'm definitely not either but I found a wiring diagram for the trucks on a Facebook group or forum somewhere that's been helpful
Lol. That’s cool. Well ty very much for helping me out
Sure helped me out
Thanks for the information
just found your channel and subbed im building a prostreet s10 on my channel

I don't I'm sorry but I do have info on what pins and corresponding wires are for what on the fuse block if that may be of some help?
Did ya figure out if that black was a ground up top?
I have not actually started hooking up wiring to the motor and such yet but hope to get back on it soon. I've been pretty busy and haven't got to spend much time working on the truck lately.
What about distributor and fule pump
do you know which wire goes to your distributor?
For the power if using an Hei distributor you should be able to use the medium size pink wire coming off the fuse block on firewall. Needs "switched power" and the the other in my case would be a green wire for the tach. I bought a pig tail that clips onto the distributor connection

I am at this point myself, I found if I take the computer out it does not prime the pump.
@@cheapskatenation what was your solution to the problem I'm dealing with a wire mess that someone else has done
@@ROOSTERBOOSTERRACING I left the computer in, from what I can tell in the diagrams, once the oil pressure sensor sees oil pressure it will kick the fuel pump back on.
How did you get the speedo to work
Will all your lights and stuff work
Yes they should all work still the wires cut were all for stuff under the hood not needed since I will be running a carb
Yes sir, Thanks
www.s10forum.com/threads/first-gen-electrical-info-thread.515438/
Here is the website I used if you scroll down through the posts theres some good information posted about what wires and pins go to what
Good job 👍 would you be interested in doin my s10
If I was near gladly help out! I saved the clipped wires just incase I need to run something from them, really don't need much from the "clipped off side" to run a sbc with carb.
What about the relay on the firewall? Does any of that get cut or no?
The relay on the wall is the fuel pump relay. I stuck with my original fuel pump. Only problem I’m having is getting my fuel pump to turn on.
Where about you in 304 are u jw I am Huntington are my self building s10 myself
Eastern panhandle
What year is your truck?
My s10 is a 93
Would this be the same for the 4 banger?
I followed a diagram I found online for the wiring. I imagine some of the stuff would be similar but I can't confirm that.
OK thanks man! I'm working on a 96 s10 build with a carbureted sb 350. It doesn't have power windows or any of the other fancy sh!t 1996 h0ad to offer lol so I'm kinda wondering just how hard the wiring could be¿
What about for gauges and dashlights
I'm going to be running mechanical gauges in mine. If you wanted to use the dash ones you wouldn't want to just clip them off. I saved the ecm and left the wires long enough to be able to fix and reuse anything down the road should I need it.

My experience is 90% of people are "Hacks" when it comes to wiring myself included, if I figured it out i'm sure he will to.
