Only swap work today was weed out the scan tool port on the S10 wired from behind the dash, Its nice using a crow bar to pull the dash instead of inbolting it
Today was the day to change pads,rotors,oil and filter and air filter.
Have to get ready for this weeks vacation to have some Maine Lobster

Starter and belt are on. I started to cut off the motor mounts but still have to clean the frame up.
Ordered the oil filter relocater nipple from Chevy today and should be here on Tuesday


Also ordered these and they should be here on Thursday


My plan is to get the mounts in and the motor in by next saturday. Now the motor is on the floor blocking the Jeep from being able to be moved.
Things are progressing nicely

Those are the best motor mounts on the market. I like them better than the Novak mounts. However, you may run into one problem... headers. [I originally went with the Advanced Adapters system to mount up my engine to a AX15 transmission. However, their hydraulic slave cylinder was a joke. It was a Toyota one and the push rod sat at damn near a 45 degree angle to the throwout arm. I even had problems with their bellhousing. I got tired of it and switched to NOVAK. Their hydraulic slave cylinder was awesome and they used a Chevy bellhousing and an adapter plate to mount the AX15 to it. (IF I WAS TO DO IT ALL OVER AGAIN, I WOULD HAVE KEPT THE ENTIRE DRIVE TRAIN CHEVY AND THEN MOUNTED IT TO THE FRAME. IT WOULD HAVE BEEN EASIER ALL AROUND. BUT LIVE AND LEARN...) ]

Anyway, I originally ordered Advanced Adapter headers but had problems with where they dumped out at. I ordered Novak headers, the block hugging type, and they interfered with my motor mounts from Advanced. I found a pair of stainless headers on eBay for a S10 for under $200 BUT I have to modify one end because it empties right into the top of the Novak slave cylinder. Anyway, any muffler shop can cut it and weld it like it has to be. When I am finished everything, I will post photos. I hope this helps you.

Take care...

Cool swap James!

The wiring is the easy part

Step 1 is finding the bulkhead diagram for your year and engine.

Next unbolt bulkhead connector from the firewall on the engine bay side (actually you remove it from the back of the fuse block under the dash). Pull back the loom and crap from the engine bay side of the bulkhead connector. You will see that it is two halves. One half (right side) goes to the lights. Remove this and set it aside with the grill. Nothing here changes.

Next is the left side. This goes to the battery, engine, pcm, and underhood fuse block. It's easier to remove this and set it up on a table than it is to try and thin it out on the firewall. Start by pushing the pcm connector through the firewall (none of this will get re-used obviously) then unplug it all and lay it out on the table.

Refer to your bulkhead diagram and remove what is unnecessary. Basically you keep all the bus circuits (powering the alternator and under-dash fuse block) gauge sending unit wires (for your dash), alternator wires, coil power, PCM power wires, and the starter solenoid wire. There's some others but it's been a while and I can't remember. If you get me your bulkhead pinout diagram I can tell you exactly what to keep and what to remove.

Also, keep the water temp and oil pressure sending units from your 4 cyl engine so you can put them in the 4.3 and keep your factory gauges.

Once all the factory engine wiring is removed, you can start on the S10 engine harness. That's pretty easy too.

^^^^^
THanks for that info!
Another day and more progress.
I split the YJ 231 that had the SYE in preperation for the other half of the NP of the 231C
Looks like a mess but its under control

Getting the motor out from under the Jeep was a bigger job that you can imagine. Even though it was on the floor tucked under the front axle. Bad idea as I had to pull it out to remove the transfer case
Now it sits waiting for the TC and the oil filter nipple. Tomorrow?

My plans are still to burn in the AA motor mounts and have the motor in the Jeep by Sunday. Moving fast. I have twins that will be 16 next month and want to drive.

231C & 231J are now combined with the SYE installed. Hardest part was keeping the pick up line in place when reassembleing.
I kept the YJ chain in but am also keeping the chevy parts as a spare.
THe job took around an hour as I had both TCs out



Tomorrow I cleaning up the engine bay of unneeded stuff
Whats funny about this picture? I had to keep the sun out of my eyes


I also picked up this today

Trying to figure out how am I going to hoist the motor in and also check for hood clearance?
Still aiming for this Saturday to get the motor in

Any other modification needed for the block besides taking off the old setup and screwing on the new nipple? I may have to do this...
