I decided it was time to start a build thread. I have been hanging around here for years. I'm not one to be able to contribute but have learned a lot from the group. This is my third s10 I've had a 83 Jimmy and a 89 Jimmy prior to the 2002 Blazer. Lots of little changes made over the years.
  • ZQ8 wheels salvaged from a yard completely redone.
  • Android head unit with blue tooth and backup camera.
  • Envoy door panels and handels.
  • Envoy console
  • Gauge cluster change.
  • LED light total replacement.
  • 4 door leather seats with heat.
  • SS mirrors with turn indicator and heat.
  • Replace rag joint with Flaming River joint
  • Hood struts
Now the next part a LS swap. I looked for a LM4 so I could keep the weight down and found one about an hour away. The salvage yard was to busy to pull it so they sold me what you see. A 2003 Envoy XL. The wire harness was cut when the pulled the transmission and it was missing the alternator. Truck was rolled but they assured me that still ran.

Now this.I want to move the C101 plug over to the drivers side and I will also clean/tuck the drooping firewall OEM wiring.

I thought about it. Have fun. Just stay clear of the exhaust manifolds and pipes and any pinch point. On the later full size, like my 04 2500HD, GM moved the PCM to the same side as the fuse box. Eliminated a lot of that back and forth wiring.

Finally got the harness buttoned up. I do hope I didn't get the cart before the horse with looming and all before installing harness. My approach wrong or right was to lay out the harness where it needed to be. I used romex wire to get wire length from the engine compartment and transmission. I used LS1swap for help and pcm tune. One thing to remember when using LS1swap is he is getting you to a stand alone harness so remove wires only when checking with what you need. I also approached this at working on one system at a time. I probably have 30 plus hrs in doing this. I do want to shout out to @oldeerslayer and of course @Harley . @oldeerslayer put me straight on the A/C wiring with the R4 compressor and the PCM tuning. @Harley was there for every question I had and I had lots. Most of the wires were extended by using matching wires with open barrel crimps. I then used 3:1 marine heat shrink wrap. I have heat shield that will be put on also.

Rad support rework to except 1989 1 3/8" radiator. I used the stock upper mounts in the top of the support after removing the second layer of material. The drivers side was cut for width and then a new patch panel pop riveted back in. The hood bracket is made from two brackets welded together. The condenser is a Ebay and Vintage air U-Ben_Em lines. The wiring harness is actually a harness sold on Ebay that I had to rework. The fans are 2005 Malibu fans that fit great just like @Tranzman said.. I used the top radiator shroud to hold the fans in against the radiator and on the bottom a bracket to hold the fans tight against the radiator. The trans cooler is from a 3500 truck that I flushed I used the stock mounting bracket rework and a bracket from a Cadillac for the bottom portion.

The radiator fan wiring looks nice. One suggestion you don't to to mount the relays upside down. They are
be prone to having water getting into them, you want them facing down so the water will drain.

Looks great! might I suggest flipping the relay pack, just thing from the standpoint of moisture accumulating.

@gimmefuel @tcmgb So right you are. Problem is not as simple as flipping the relays. They are not sealed so I would probably still have an issue. I decided to save the relays and put them in a water tight 4" electrical box. I has a gasket lid. I removed the inside posts and added studs so I could make it easy to remove the lid. I also used liquid tight pushin gourmets.

Why didn't you use weather proof relays? Here's the link to the weather sealed relays I used.

I bought the relays from Ebay as a made up set with fan connectors and wires.I didn't realize the relays were not sealed.So yes I could of scrap the relays and bought new and repined but since I already had the setup I decided to just put them in a sealed box.

Okay I see. The company that makes them over in China I'm sure their cost is only a few cents more to use weather proof but they're too much of a penny pincher to do that. But that's just me. being in the car audio and video & security field for the last 35 + years I would spend the extra few pennies then make sure the customer didn't come back. Especially if they live in the snow that salt will eat those relays terminals up in a quickness.
I made my own relay harness and I put the weather proof relays right behind the under hood fuse box. And grab power right off the extra stud in the fuse box which is already fused.

In hind sight I wish I would have bought and made my own. At the time it looked to be a complete nice package for a low cost. It is well made but with bad cheap relays.

While my block is getting cleaned up and new cam bearings installed I am still loading the cannon. Found a 1991 camaro A/C hose line to go with my 92 camaro R4 compressor.. This should work better than the 92 S10 hose setup. will tuck nicely .

I used a 94 4.3 S10 hose. Looks pretty much the same.
Yes the 92 s10 will look like the 94. I wanted hoses not to run over the top of the compressor and then back. The camaro has it tucked over to the side and down. Just my anal retentive.

Had some time on my hands waiting for the engine work so I work over the valve covers and coils brackets. I shaved the two unused lower studs off of the valve covers and removed a lot of metal from the coil brackets.

Looking good. I've thought about button head allen bolts to attach the coils and brackets. Stainless if you like shiny.

I would take those freshly painted valve covers and coil brackets and bake them in the oven at 250° for about 2 hours that will harden the paint and make it last longer. Do not go over 250° or it will give the paint a brown tent to it.
