Small update

Finally got back on it after addressing some priority stuff around here.

I was planning on moving onto the wiring after I buttoned up the Y-pipe. I had the Y-pipe and muffler fitted but did not fully tighten everything up. With the plan to fire it up after the wiring is far enough to get it running I had to tighten the exhaust. You can see how close the header collector flange is to the bell housing and firewall/floor, especially on the passenger side. I was only able to get one bolt in and fumbled with another and one not at all. It was so awkward that I pulled the header off and extended the down pipe to make the connection under the floor. It wasn't something I really wanted to redo, but I'm glad I did. The header still drops in just as easy, but now I just slip a band clamp over the joint and it's done.
Image

The last 3 days I've been shortening the engine harness and rerouting wires. So far over 100 splices! The harness is considerably bulkier than I had thought, but I don't care, it's not a show car.
I fired it up tonight. Started right up like a DD should. The cheapo muffler sounds good! Deep purr.

I'll post up some pics later this week, maybe a video.

Shift linkage & shifter reworked for the 4 speed auto

Objective: to use the stock shift lever inside the Jeep, 3 speed shifter for 4 speed transmission. Keep the interior looking as stock as possible, no custom shifter. Also I'm too cheap to spend the money on a custom shifter.

I used the lever off the Jeep transmission and cut it down and temporarily tacked it to the GM transmission shift lever so I could figure the geometry. (no pic)

I cut down the Jeep shift cable support bracket to attach to a custom bracket I made for the 4L80
Image

Drill mounting holes in it.
Image

Then I attached the Jeep shifter cable to it. The Jeep cable will now attach to the GM transmission because I attached the Jeep lever to the GM lever.
Image

I moved the shifter through the gears and made a few small corrections to the position of the Jeep lever to match the travel of the cable to the travel of the transmission shift lever. Once I had from Park to #1 gear over the span of the shifter travel I marked out the positions of the gears on the Jeep shifter detent so they would match the transmission detents.
Image

I removed the shifter detent and reworked it so the detents matched my markings.
Image

Reassembled the shifter detent.
Image

Now the real cool part. :mrgreen:

I took the console shift indicator apart, hot knife through the plastic assembly welds.
Image
Image

I put the shifter through the motions and marked where each gear position was.

I took the plastic piece that has the PRND31-2 and sanded off the paint so it was clear.

I have a family member who works in a sign/decal shop. I marked out the gear postions on the shift indicator in the console.
Image

I gave him the tape marked piece and he made a new decal that replaced the old markings, so now I have the correct markings for a 4 speed auto.
Image

Installed and backlit.

Update

I wanted to get this thing sitting on it's own wheels, sort of. I had the 8.8 chained up to the leaf springs so it would sit and roll around, but because the tires are so close to the leaf springs the rear end would shift and then it would not roll and it would also shift off center on my hoist if I let it rest on the wheels, so next time I lifted it I would need to remember to re-position my hoist arms, VERY important.

I got the spring perches removed, needs to be spring over now, not spring under.
Image

Picked up some new perches from the spring shop. I set the axle on jack stands to replicate the ride height of the axle with the wheels on. Need to do this to set the pinion angle. I gently set the Cherokee down with the perches loose so I could shift the diff to get the wheels positioned left & right.
Image

I measured from the caliper mount to the spring and adjusted so each side was equal.
Image

With that done I crawled under and read the inclinometer on the transmission rail and duplicated the pinion angle by tilting the diff up or down. Once that was done I tacked the perches in place.

Measured up for my drive shaft to be shortened. I had an aluminum drive shaft from an Aerostar. Turns out the 8.8 in the Aerostar uses a different pinion flange. The opening for the pinion nut wasn't big enough, I had to have the shop supply an Explorer one. Also the slip yoke in the 4l80 uses too large a U-joint to be compatible with the Areostar drive shaft.

But I got it done.
Image
Image

Mocked up my shock mounts.
Image
Image

A couple of coats of paint now that it's all welded up.
Image

So now to do the rear brakes and then back to wiring. Just need to wrap the loom up using Tesa tape. For those that do not know, Tesa tape is what the German auto manufacturers use. It's a fabric tape that is super super sticky, and the adhesive will not release with the under hood heat. It is super strong stuff. Very hard to find here. I had to order off eBay. 20 bucks for 4 rolls, 25 yards each.

Then need to integrate the LS harness into the Jeep's system, fuel pump, ignition, etc. Then it's drop the rad in, hoses and put the grill back on then then burn rubber!

8.8 rear end is installed. It went much quicker than I had thought.
Spring pads welded in place, shock mounts made and the whole works installed.

I got the engine harness cleaned up and wrapped with Tesa tape. What, you haven't heard of Tesa tape!
This is the best kept trade secret. Tesa brand tape is a cloth tape that is used by VW, BMW & MB on their engine harnesses. It forms itself very well as you wrap it. It sticks REALLY well and is very resistant to underhood temps. It does not relax with heat and release itself.
Image

I've just got to mount my little swap fuse boxes and wire the engine harness into the Jeep's system.

Rear brakes are done. Just a good clean up and new pads.
Image

The biggest relief was getting the rad & fan installed. I had fabbed something up but was not really feeling it was my best work. I didn't like how the rad was supported and the cooling fan didn't fit as nice as I had hoped.
I redid the lower rad support and used a piece of 1 x 2 tubing with some foam strips to support it.
Image

Image

The Taurus fan is a bit too long for the core so I cut it down.
Image

Reworked the shroud and fabbed a support of the lower rad support.
Image

Installed and looking purdy!
Image

I've just got the rad wired on low right now. It still moves a lot of air. If I find out I need more cooling I can wire the high speed.

I've got 3/4" between the fan & the water pump pulley.

Here is a Youtube video with a quick look around on the rad & fan.
https://www.youtube.com/watch?v=MU_OLe77lcI

Hoses look straight forward. Spent a few minutes looking at the rad hoses on the wall, picked out 6 that I thought I could make work. 4 will and I just need one pipe to complete the system.

I can already smell the burning rubber!

Just a quick teaser for you all.

I just got it running again after the VATS had locked up the PCM. This morning fired it up to bring it back into the shop, just couldn't resist a little play time.

Small update

Since disabling the VATS I've moved onto the cooling fan controls as I can now program the PCM to control them. I bought a couple of PICO relays and sockets. I used jumpers to temporarily make all the connections. I simulated the ground signals of the PCM and the relays operated the fans. I soldered and shrink tubed everything and started the engine. I was watching my scanner for the magic temp to arise but nothing happened. After it passed the required temp by several degrees I decided to investigate.

I've done many many relay installations, and so far on this I've not had one circuit that I've wired wrong.

I check the relays for and the PCM wires for ground, all was good. I pulled the low speed relay out and checked the socket connections for power & ground. The power in connection was dead. I checked the relay and it had fried itself. The 25 amp fuse was still good but the relay was toast, and it burned the socket connection.

I went and picked up some Hella relays and sockets, much better quality. Rewired the new relays and everything's a go. The fan on low cools the idling engine down from 93ºC to 89ºC in less than a minute. With the hood down the fan is hardly noticeable.

Now I've got just the speedo and tach left to wire up and I'm done under the hood.

I've got several little things to tidy up and it'll be ready for the road, maybe another couple of weeks.

That squealing sound is how my camera picks up the sound. No squeal in real life.
