Started on putting the engine harness back together.
Lay it back on the engine and start plugging wires in.
Pull them together and tape every time a wire goes in or out of the loom.
Just keep going along
That's a lot of wires....
Looking better....
Took today to try and wrap it up....wiring is taking longer than I expected. But progress none the less.
I laid the harness back out on the engine....now off the engine and repinned to the connectors. Looking like the PCM will reach into the glovebox.
Rewrapping the harness
Laying it back out on the engine
Still more to clean up...wires can be tied into the e12 harness now..
The extra fuse/relay box.
Intake is coming together
Now I wasn't expecting that filter was going to be that big....
Both of these filters have a 3.5" inlet.... The one on the right really isn't that small either.
The filter I ordered is just about the same size as my head.
More wiring....engine side is done and all wrapped up for the most part. Still need to connect the grounds. Next up I can tie the LSx harness into the BMW harness. The e12 has some weird wiring so I am trying to track down where the fuel pump feeds from.
Some pictures....
Made the hole bigger going into the car
PCM connectors reach without extending wires!! very good
You can also see the wires separated coming from the extra fuse box.
You can't really see but where the wires turn towards the inside of the car I make some little marks with a marker so I can keep things lined up.
Then just like a cooking show...20 minutes in the oven and we are done
OBDII Port and other wires that will go into the cabin, CEL, VSS signal for speedo, power/ground for speedo, and one extra power line. (wideband for tuning if needed)
Wires over at the drivers side where they will tie into the fuse box. coolant temp, oil psi, tach, fuel pump, 12v switched, start signal
Just another angle showing the routing.
Little bit by little bit....
Wires going to the crank sensor, starter solenoid, and gauge temp sensor. Wraped in heat tape as they are all pretty close to the exhaust. That is how GM does it as well so...
New harness tied into the e12 fuse box. These wires will get wrapped.
AC pressure fitting that needs to be brazed together
A couple other things done but no pictures...or really pictures required. Negative cable to block/battery fuel line connected
Plugged the PCM in about 30 minutes ago and powered it all up. PCM primed the fuel pump and is working. Did a read entire with HP tuners so I can pull out VATS and other unneeded things. VATS is like EWS in the BMW world.
I did have one issue with how the unloader relay works...when I turned the key to on (not crank) the engine started cranking. I used a start relay because that is how GM does it and the fuse/relay panel I got came wired that way. I will just have to run a wire direct to the starter solenoid the way BMW wants it. Easy fix....
e12 with an OBDII Port connected to a laptop....... :)
Intake setup is made...the filter might need to change to something a little smaller...not sure if the hood will close. But it will work for now.
It's running!!
I can never remember how to flip the iphone to get the right orientation for youtube....
Either way here are a couple videos. I will get some better ones eventually. The little light in the engine bay is a oil pressure light. You can hear it quiet down once the light goes off.
This is the first start http://www.youtube.com/watch?v=39tCSraGwUE&feature=plcp
A little blip...you can hear a slightly choppy idle from the cam. http://www.youtube.com/watch?v=tv6A3z0JotU&feature=plcp
Congrats! That looks like an awesome project!
thanks guys, glad it is running! After a little research it looks like the pushrods are a little short. So I have a set of 7.450 on order. The ones in it now are 7.400. That should add a bit more preload on the lifters and quiet down the valve train some.
Worked on the AC lines today.
These are the crimped low side to compressor (short line) and high side from compressor to condenser.
In the tool and pre crimp
post crimp
Entire crimping tool/setup
Heater hoses also done...AC lines feeding up to the drier (not connected yet) and the low side to the evap.
Bad picture...but where it goes up front..
Other side before it goes to the condenser.
Hooking to the condenser
I recall making AC/Hydraulic hoses in my days at the auto parts store. Neat setup you have.
I have that same impact wrench... love it.
Where did you get that crimp tool and where do you get your supplies? Neat setup!
Yeah I dig my impact as well. I bought the 3/8 version when they were on clearance for around $30.
Crimp tool I got on ebay or amazon...it is made by mastercool. Goes from $150-200 depending where you buy it. I has used it on three different AC projects so far so it is slowly paying for itseld.
I get all my crimps from www.coldhose.com
Master cylinder is back on....getting those lines all hooked up was a BITCH. Mostly the ones on the bottom. Hard to push up and turn at the same time. Either way it is hooked up......#5 coil will have to be relocated a little to clear the reservoir.
Upper radiator hose and efan. I looked for a single hose but couldn't find anything to do what I wanted/needed. So two hoses with a coupler will work. efan is a 16" puller...high and low speed controlled by the GM PCM.
As luck would have it the lower hose worked out being the left over piece/bend from the upper hose hooked to the radiator.
alternator/belt/etc are all on
New sway bar mounts tacked on. Once I am happy with them it will get fully welded.
I was able to get the end link connected...it is at a slight angle. When I go to have it aligned I will look it over a bit better as the weight will be fully on the wheels and I can see how everything is sitting. End links are not fully tightened as well.
blurry pic but it is coming along....
Speedo is done...
I was going to mount the odometer/trip button in the under column panel but then I noticed how the odometer reset worked for the mechanical speedo.
Add a button..
All put together
In the car
How it all works..... I think it came out pretty stock looking. http://www.youtube.com/watch?v=g-d8tOvXeek
Very nice!
Congratulations on being largely responsible for me having an E12/E28 CL search set up in my RSS feeds...
hahaha, nice!
I really need to learn how to do CL RSS feeds...it would make things easier. Or maybe I would end up owning 50 cars.
You do fine work. 
thanks!
E12 came off the lift today and made a small loop around the block. The sway bar mounts are not fully welded so I didn't want to drive all that much.
Things are coming together....a couple small things that need to be tended too. Exhaust leak from one of the couplers, alternator not charging....
Back on the ground and in the day light...
Quick walk around video http://www.youtube.com/watch?v=BqNou_hcY3g
I have been fixing a couple small things the past couple weeks. Small exhaust leaks, oxygen sensor not giving a reading (bad connector not allowing the heater to work), etc
Here is the bad O2 sensor connector. It was pushing the mating connector out and not allowing them to plug together.
Because of the lack of room I wasn't able to use a flange to keep the pipes together so I had to use band clamps. They were not sealing...mostly because I wasn't cranking them down enough. 70-80ft lbs and now they are sealing.
Leaks are sealed up...got it aligned today. And now on to doing some adjustments to the tune. The PCM is from a 2002 camaro but then I blind adjusted it somewhat and it needs more fueling from what I have logged so far. The PCM will pull it back with the O2 sensors to stoich but it is much better to have the tune very close and not need the PCM to adjust so much.
A couple pictures of the just about finished engine bay. Still need to swap the AC drier, fill the AC, and put the strut tower brace back on.
Car is back to Blunt now...
A couple finished pictures to post.
Man I want one of those.
I dig E28s a lot, but there's something even cooler about E12s...
Awesome work! Is Blunt going to leave it ragged looking, or make it pretty with new paint?
